2020 Silverado HD Allison Transmission Isn’t Really An Allison70
The 2020 Chevrolet Silverado HD debuted this week to some, uh, strong reactions.
But while many folks on the internet may not be a fan of the Heavy Duty Silverado’s exterior looks, at least the powertrain seems rock solid: a new gas engine, an available Duramax turbo diesel V8 with 910 lb-ft of torque and a new Allison 10-speed automatic transmission. What’s not to like about that?
There’s one interesting tidbit of information about the 2020 Silverado HD’s hardware you may not have heard yet, though. That new Allison 10-speed isn’t actually made by the familiar Indianapolis-based engineering firm. It will be built in-house by General Motors and simply features Allison branding. The transmission isn’t closely related to the 10-speed automatic found in the 2019 Silverado 1500, as far as we can tell, with General Motors describing the Allison-branded unit as “all-new.”
The only way to get a true Allison-built transmission in your Silverado is to opt for the new Silverado 4500, 5500 and 6500 medium-duty trucks. These monsters will feature an Allison-designed and built six-speed automatic transmission. The new six-speed was developed in conjunction with GM and is designed specifically for use in the gargantuan medium duty Chevys.
It’s not surprising that GM wanted Allison branding on the side of the 2020 Silverado HD. The company is the world’s largest purveyor of automatic transmissions for heavy duty and commercial vehicle applications and has been a mainstay on GM trucks since the 1950s. Chevy’s hard working HD customers have come to know and trust the Allison name and seeing the branding on the side of the truck might give them some reassurance that this new truck isn’t such a departure from older versions of the Silverado HD.
The 2020 Silverado HD will be built at GM’s Flint Assembly plant in Flint, Michigan and will be available in the United States, Canada and Mexico. Pricing has yet to be announced, but stay tuned to GM Authority for more 2020 Silverado HD news and information as it becomes available.

Yep two things GM HD truck owners have come to trust over the years, Duramax and Allison. First GM switches plant people at Duramax plant, and now NO Allison transmission. Can we all say BEANCOUNTER together. When it comes to GM truck owners most remember transmission troubles from the past when it was left to GM. If it wasn’t for ISUZU and ALLISON, GM wouldn’t even have a HD truck. In fact GM quit the diesel truck do to terrible diesel engine and terrible transmission for a couple years I think. This news is the MOST disturbing news yet. If you read the transmission troubles GM has, or have owned one with terrible shift patterns and clunks or lurches, this is NOT good news. To top that off the GM warranty for HORRIBLE transmission troubles is THERE IS NO WARRANTY, it is normal operation of the vehicle , live with it straight to another brand of vehicle. For sure FORD will LOVE this news. Just one 38 year GM truck owners OPINION.
Why would it benefit Ford? They have had just as many transmission problems as GM over the last decade. The 2015 F-150’s 6-speed had as many or more issues than the 6L80 in the 2014-15 Silverado 1500’s. Even Fords 10-speed clunks, slams on downshifts, and gets confused. The first year Ford put them in an F-150 they were groaning, honking, and knocking as you drove down the road. Then Ford put a weaker, cheaper 6-speed in the 2017 Super Duty gassers and created all kinds of new problems. They don’t get a pass.
This 10-speed is tested and validated by Allison. They wouldn’t risk the reputation their name carries by slapping it on a transmission they didn’t trust.
Blackdragon is right. Additionally, lifelongGMowner has no clue what he is talking about because GMC built HD trucks long before Ford or Chevrolet did…spanning over a hundred years until GM killed medium duty truck production in 2009. GM diesel engine options had nothing to do with Isuzu until the late 90’s.
First I am talking 3/4 ton or HD as they now say. I am well – aware of GMC truck history, at least into the 50,s. I was born in 1968 however my grandpa and all neighbors had GM. GM pickups, GM grain trucks, 292,s 283,s 350,s 366BB,s 400BB,s
The 1960, 292 4 speed of the neighbors NO TROUBLE.
The 1966, 283 4 speed , best friends dad, NO TROUBLES. First engine I ever rebuilt 1966 283.
Now I will try to keep this short. We had and have owned way to many to keep track of ( my uncle however has a log of everyone in the families autos way back to the 50,s.)
In the 70’s when GM went from the 400TH transmission, and we had one 1972 400BB with400TH transmission, to the 350TH transmission. Where I am from in the 3/4 ton GM pickup they were going out left and right. Its the first of over 100s of GM transmissions I have rebuilt. Everyone was having 350 transmission troubles in 3/4 ton pickups that were used. Sure the 1/2 ton people haulers and grocery getters were fine. Then in the 80,s GM started the 6.2 Diesel and 700R4 nightmare this is where and when we first heard of ISUZU. I owned three 80,s pickups with 6.2 Diesels and 700R4 transmissions. Cracked heads, new RoosaMaster fuel pumps with the disintegrating flex joint. 700R4 second gear bands burning out, overdrive planetary gear sets burning up, shift kits with drill this out, install that rubber ball in the valve body, all of it. Then the 6.5 Turbo Combo even worse, well maybe not, hard to get much worse.
Now the 700R4 after about 5 years of total hell GM finally started getting it to work. Then like GM scrapped the NAME and called it a 4L60E, 4L65E, By then maybe average to the competition.
GM Quit the 3/4 Ton Diesel in 1993 it was rolled out in 1992 and quit in 1993, both my brother and brother in law had at least one.
Now I can tell you how many of those people still drive GM trucks but it will make a GM guy SAD. My brother and I still do. Uncle RAM. His son Toyota. Other uncle GM, two of his three sons RAM. Brother in law FORD. All three sons FORD.
It was in that time frame when GM and the ISUZU -DURAMAX with the ALLISON transmission was born. AND it was in that time frame when FORD became the #1 selling pickup. Now I can NOT speak for the rest of the USA but where I am from it was those days that hurt the GM pickup sales the most.
Most that switched haven’t hated the brand they drive now to switch back.
I had a farmer tell me he switched to FORD because he was worried about his daughters getting home with there horses after a rodeo with that GM transmission.
We all have our stories but I will say it again, I have never owned a GM truck that did not have transmission troubles other than a 4 speed manual or an Allison. Not to say GM can’t, or has not made one. I just have never owned one.
Of all the truck transmissions in the past 100 years, GM by far outperforms Ford and especially Dodge. Any sane diesel mechanic will tell you the perfect truck would be a Ford frame with a Cummins diesel and an GM/Allison trans. Allison has been making transmissions for GM HD trucks the better part of the last century, since GM bought them in 1929. So the DMAX combo of the late 90’s was not the first occurrence. Most of your 6.2/6.5 Detroit Diesels came with Allison…because they were made in the same factory. The 70′-90’s GM CUCV and GM 3/4 ton had them, numerous heavy duty GM trucks had them as well. And before that, they were plopping them in the GMC medium duty trucks. Just because you had a bad experience or know someone who did doesn’t mean that’s how they all were. Being a veteran, I can tell you the GM trucks held up much longer than anything else in the military inventory…and trust me we beat the crap out of them…that’s why you still see them a dime a dozen today in surplus auctions, because they still work fine 40 years later.
From the Allison web site: http://ir.allisontransmission.com/news-releases/news-release-details/chevrolet-offer-10-speed-fully-automatic-allison-branded Clearly, the 10 Speed Allison Automatic is manufactured by GM, and co-developed by both companies. As long as they continue to work well together, we can only expect constant advances. Japanese manufacturers have worked together well in many instances for a very long time. It works.
You are an idiot. GM used to own Allison transmission. GM only recently sold Allison to the carlyle group & onex corporation. Stop talking out loud.
you couldnt be any MORE WRONG, GM OWNEND ALLISON! LMFAO GM bought Allison in 1929 and made 12 cylinder engines for airplanes they were a MAJOR force in aviation. Toward the end of WWII GM”Allison” started making transmissions for tanks.. TANKS and military vehicles. After that they turned to civilian transportation and made the first ever automatic transmissions for heavy duty vehicles, delivery trucks, city buses and trains. While GM owned allison in 1949 they made the CD-850 tank transmission the renowned transmission was historically significant and known as one of the best transmissions ever made.. EVER. From 1949 to 1987 GM”Allison” made transmissions for all american military vehicles. In 1969 GM”Allison” also helped NASA build actual propellant tanks aiding them on the voyage to the moon. It wouldn’t be until late 1987 where Detroit Diesel Allison becomes Allison Transmission, Division of General Motors. From that point on Allison would continue to make transmissions for GM trucks until June 2007—GM sells Allison Transmission to private equity firms The Carlyle Group and Onex Corporation, in a deal valued at $5.6 billion. The transaction closed on August 7, 2007. Please do your research before posting random nonsense. Thank you.
Not sure how GM can get away with false advertisement! All smoke and mirrors approach misleading everyone to think they are driving with the Allison because of the badge! They know if they were honest they would lose too many sales. Shame on GM!
Actually Ford and GM BOTH developed and will use the new 10 speed trans. I have driven and towed (20,000lb 5th wheel) with new 10 speed and I really like it in my 3500HD dually.
I have a theory:
GM and Ford have a pact where they are helping each other out in these times of slowing auto sales.
GM would take over Fords sedan sales when cars like the Fusion, and Fiesta go away. In turn, GM would start to really drop the bar for their new and “improved” Trucks so more customers would go to Ford.
I personally like the looks of the new Silverado in person, the interior is great too. Its very simple (which is exactly what a truck should be). However, between the small gas tank, the small mirrors, the 4-cylinder engine with bad MPG. Its was just so over hyper before launch.
Now we see the design of the new HD’s (that looks just absolutely awful IMO), as well as a “fake” Allison trans. This is already disappointing. Even the loss of the 6.0 hits home, it may be outdated but it is a great option for someone who wants something that is tried and true.
I think this is false advertising. I don’t like this at all. Is the truck really a Chevrolet or is it just licensed by them? I don’t think they should be allowed to say that it has an Allison transmission if it does not.
I don’t think this article has enough information, did Allison help design this new one???? Even the last Allison transmission was built in a GM plant. I don’t think it’s too big of deal.
What in the hell is going on at GM and why are investors allowing this? Is Mary Barre not being fired because she is a minority? I lost an investment in GM once but stayed loyal but now, I can’t say that I will.
The leadership at GM is abysmal and this “transformation for the future” is more about throwing in the towel on today!
What will you do GM when you finally alienate your customer base with bizarre design and lackluster products to the point they leave and then find out the millennials or whomever you are pursuing don’t care for your products anyway?! I have not met one “car guy” that wants your autonomy or electrification and those “car guys” ,both male and female, are the people that buy your products, not the techies who don’t have a passion for vehicles or driving in the first place!!
The Board of Directors themselves are no more concerned with the turn of recent events than those aforementioned techies, but sooner or later another crisis will strike GM because of this leaderships decisions and then what? Ask for another loan? Tell us what we want to drive and ignore what we ask for again?
I say it’s time to dissolve General Motors entirely! It is still too big, too powerful and too out of touch with the needs of a common man/buyer. “Dance with the one that brought you” funny, GM went home with someone else, but what will happen in the morning?
I have to agree this is the worst news for the HD customer. The in house transmissions are not great products. Having personal experience with the 4L60 crap sifts, the 2014 truck 6 speed more crap shifts and now the 2017 8 speed that i thought would have been a better unit but was wrong crap shifts again bangs at times and gets confused what to do at low speeds. The last good trans i had from GM was the 4L80 solid sifts no hunting for correct gears. I have great confidence the few trans mechanics that are out there will be even more overwhelmed with this new POS trans. It is really a sad day i am blown away Allison would let GM soil there solid name with this product.
I would agree regarding the sentiment that GM’s automatic transmissions leave a lot to be desired in terms of refinement. That said, the new 10-speed unit is VERY good (probably because it was developed by Ford and GM together).
Alex, I would like to hear your honest opinion about all the recently news about GM and GM direction.
The automatic transmission is the most complex part of a car and any manufacturer (car or transmission, I.E. ZF) that has designed and built them in large numbers will have their gems and duds.
Is this 10 speed in the HD the same as in the 1500 with 6.2. I drove one with the 6.2 last Saturday and was impressed with the shift pattern over ANY GM I have ever driven. Just wasn’t sure the 1500 10 speed could handle the Duramax torque. And why does the 6.2 in the 1500 have a 10 speed but the larger gas in the new HD not have a 10 speed. I don’t get it. What am I missing?
No. It’s not the same.
All that for upgrading to an LTZ or High Country model and another $2495 tax not included.
With the Allison branding, Allison engineers might have overlooked the project to be sure it meets their standards. They have to protect their name and reputation, not just collect a loyalty fee.
I told you about this 2 years ago. The builders of the current 6 speed have been building it since 2000. They have been out from under the Allison umbrella for years and have continued to build and improve on the Allison designed transmission.
So is a deceptive advertising.
BADGE Engineering …. Nothing new for GM ……………..
they know how it worked in past ……
soooo when Ford built the new powerstroke “in-house”… that’s different somehow?
Not a Ford guy but it is different. Powerstroke is Ford’s moniker. Ford is not saying it is an International engine a company separate from Ford. GM is saying this is Allison when it is not. Allison is separate from GM. ANd this is not an Allison transmission although Allison may have had some input.
Let’s try to sort through some of the nonsense here. I’m sure most bashing this move have no idea that Allison was a wholly owned subsidiary of GM from 1929 to 2007 when it was sold to a private equity group. If GM and Allison want to create a GM built Allison have no doubt it will be just as solid and reliable as Allison built light transmissions. The light truck market was never a big profit center for Allison an GM is likely banking on selling more Duramax diesel/Allison packages than Allison has interest in making, remember Allison is investing massive amounts of cash in hybrid and electric drive systems. Allison’s in GM light trucks make up like 2% of Allison’s revenue. One could argue that the light truck Allison wasn’t really an Allison either, in fact that was exactly what was said we’re they we’re new, they we’re not based on anything previously built, just an all new design for light truck market because corporate parent GM wanted to put that name behind the Duramax to set them selves apart from Ford and Dodge who had absolutely abyssmal transmissions at the time.
Read the original press release, if Allison wants to develop and certify a new transmission in conjunction with GM to be built in a GM plant, so be it, it is no less an Allison than the previous generation to me. Most of the equipment on the road today is built by companies other than the name on the grille. I’ve been involved in teir 1 oem automotive manufacturing and supply for 25 years, the name on the car or even part means nothing in teams of where the part actually was made, just the standard that needs to be adhered to.
Unlike most who would bash this move who have never even owned a Duramax or an Allison, I can say I’ve had several Allison’s in GM trucks, both behind Duramax’s and 8.1 vortec’s, all 2007 and prior when Allison was GM and have always been impressed.
very well said!
Prove something, anything, words, more words, more words. I myself am getting tired of words. Words mean NOTHING. You have a warranty, words. Believe me it will be great, words, All words. Prove something, do something. Agreed Allison was together with GM for a period, I think. GM and Allison worked together for military tanks, I think. Allison was sold to a private equity group, I think. What I know is before Allison transmissions I had GM transmission troubles, I know FACT. Other GM transmissions made by GM I know I have had shifting troubles with, I know, FACT. NOTHING has been done by GM to address ANY transmission trouble I have EVER had, I know FACT. Other people I know personally, family and friends have had GM transmission troubles, and have bought FORD, RAM, and Toyota because of it, FACT.
Now I don’t care one bit what WORDS by ANY GM person are spoken, I have heard them ALL, FACT.
What I DO care is I have NEVER had ONE bit of trouble with an Alisson transmission, FACT.
Sure Allison was sold to an equity group. A group who was smart enough, AND spent money enough, to develop a product for NO FAILURE.
Military NO FAILURE, Heavy Duty Trucking NO FAILURE.
GM and its money decisions are not that equity group, FACT. IT IS GM, FACT.
Maybe we could get an Allison warranty on this NEW GREAT GM TRANSMISSION. Did you hear that, a new great GM transmission.
When is the last time GM made ANYTHING, NEW and GREAT.
GM has NEVER been known to make a good transmission, NEVER.
Sur people will say ” well I didn’t have trouble with mine”, “Well mine lasted 400,000 miles with no trouble”, sure that’s great I believe them, I to have driven GM products that have had no transmission troubles.
But HEAR this. Unless it was a manual 4 speed, or an Allison, I have NEVER owned a GM pickup that did NOT have transmission troubles, FACT.
I would like to hear from Allison on this new ” Allison co-developed, Allison tested” GM transmission.
GM, This is kind of news is getting old.
This would not bother me one bit if GM stood behind ANY vehicle. If GM had ANY Customer Service to speak of at all. GM will sell these NEW HD trucks to the dealers and it will be left to the dealers to try to handle of fix the coming transmission troubles.
You know GM: “We are sorry to hear that you are having trouble with your new HD truck. Your satisfaction is very important to us”. “For us to be of further assistance, we would like you to provide us with your dealer information”. WORDS, WORDS, WORDS.
Sounds like there’s a new Ram HD in your future since the Ford HD’s will have the same 10 speed as GM!
Well I WAS getting a NEW 2020 Denali HD Duramax. I’m just not sure after this news. I think I will sell my 2017 Denali HD Duramax with 12,000 miles. Then I will search out 3 of the lowest mileage 2007 Classic HD Duramax LBZ Silverados. Get one tuned deleted and run them. Then get rid of our Cadillac ATS and get an Audi A4 and be done with GM once and for all after 38 years. By the time I run the life out of those choices GM will either be bankrupt again, or some of the NEW GREAT stuff will be proven.
Good luck with the Volkswagen!
Why Thank You.
I’ll buy it from the same Audi dealer my cousin has bought his last two Audi A7s from. He has had ZERO troubles, says he’s treated GREAT there. We already have been there and test drove one, it makes our ATS feel like total junk. We were waiting for the new Chevrollac CT5 before we made our decision just because it would have been our 6th Cadillac but after all this GM shit show lately I think it will be a good time to move on. My cousin also drives a Tundra and has had ZERO troubles but I need more truck than they offer. His dad my uncle drives a new RAM however, not HD, and a Mercedes sedan.
If I didn’t know better I would think you worked for GM customer service with that genuine concern.
Is Ford going to sell to Volkswagen or won’t the Ford family sell there interest so it will just be a partnership agreement.
Man the next year will be interesting.
So we need to buy a Ram Cummins with Aison transmission which is made by Toyota! WTH
My cranky younger brother has put a lot of thought into the concept of an ‘ideal combination’. His decision is Ford F150 Superduty, with the Cummins engine and the Alison transmission. I have to admit that he is probably right on the balance of comfort, power and reliability. But I am convinced that the Duramax is the better option.
My first Allison was a disaster.
2001 and GM never helped.
I’m really glad they went bankrupt.
So…………I will try one again if they give me one.
lifelongGMowner, you sound like you are no longer a GM owner to me ,with that much hate ! If you now drive a different brand of vehicle good for you ! I have owned Chevy trucks ,with problems , But never with a transmission! I head trouble with 6.5 diesel injectors ,that Gm tried to repair it , So after a second time to shop and after the repair ,I traded the truck for gas power 350 3/4 ton GMC and head no problems ! I still drive a GM truck and happy !
I agree the Gas was good. My brother and brother in law both had 6.5 and both had head troubles. I had 6.2 and had head troubles. The transmission troubles were the 700R4 in the early 80s so you probably had the 4L60E or 4L65E they were good to average IMO. And I still drive a 2015 GMC Canyon (transmission troubles) and a 2017 Denali HD Duramax Allison.
What do you drive now?
No hate just disappointment.
2012-16 DPS6 Powershift transmission used in the 2012-16 Focus and 2011-16 Fiesta sedans
This transmission is the subject of a massive number of lawsuits alleging Ford lied in order to sell cars Ford knew had defective transmissions
Yeah ford doesn’t really do transmissions any more LMFAO they get them from GM or ZF
Learn your facts buddy
To set the record straight I did a little digging.
“We built the new 2020 Silverado HD with more differentiation than ever before, to meet the needs and priorities of our customers,” said Jaclyn McQuaid, chief engineer, Silverado HD. “By offering the new Allison 10-speed, tested and validated in partnership with Allison Transmission, each transmission will deliver the legendary quality and durability that customers have come to expect.”
Famous last words. As a current owner of a 2015 Chevy Silverado 1500 with the disastrous 6 speed transmission I can honestly say that she is LYING. GM has no customer service when it comes to the 6 & 8 speed transmissions. I have taken my truck back too many times to count and all I get is “it’s normal”. I finally got a transmission guy at my dealer to ride along to show him all the problems I’m having and he said “Yeah they shift like shit. There’s nothing we at the dealer can do about it because if we try to fix it and something breaks the dealer is responsible. GM has pretty much washed their hands of this transmission.”
Go to https://www.gmtruckclub.com/forum/ and search on your transmission problem. About a year ago, maybe more, a Silverado owner had similar issues. He found a tuner shop, deactivated AFM and tuned the shift points. It was 100% improvement.
I can only tell you that my first experience with Allison tells me it was a piece of shit.
I had one when they first came out and it locked in 4 th gear.
My recommendation is to wait a year to buy any new model or design.
Female lead engineer for HD truck program, what could go wrong? I’m glad the new truck represents Mary Barra having a gender neutral workforce.. Fingers crossed, maybe they will have better visor mirrors etc?
Amen. Sounds like the new GM is starting to do the same stupid stuff that the old GM did. Where GM was it worst enemy. Cutting it nose off to spite it face. Building cars by commitee.
I like it. First time that I can recall that the 2500HD looks different and not a beefed up 1500 grill. If looks can kill….
And what proof is there that this is the case?
Reminds me of when a Cavalier became a Cadillac, the Cimarron.
Nevermind, I answered my own question since you guys can’t even cite a source. Great journalism.
“Allison Transmission Holdings Inc. (NYSE: ALSN), the largest global provider of commercial duty fully automatic transmissions, announced today, along with Chevrolet, the availability of a 10-speed, fully automatic transmission in the new Class 2/3, 2020 Silverado 2500/3500 HD trucks. Equipped with the Allison branded 10-speed transmission, the 2020 Silverado HD will debut in February 2019.
The Allison branded automatic transmission, manufactured by General Motors, combines enhanced performance and fuel economy, greater operational flexibility, and improved driver comfort and control, with an industry-leading reputation for uptime and reliability. Designed for high-performance and low-maintenance, the Allison 10-speed coupled with Chevrolet’s Duramax diesel engines provide the superior power delivery and productivity customers demand.”
We are the source for this.
GM Authority learned this information after several interviews and did the legwork on it before this was even public.
That is what real journalism is.
But hey, thanks for incorrectly assuming. Apology accepted.
TFLtruck even cites the Businesswire article and not this one, covering the exact same topic. https://www.youtube.com/watch?v=bxYtib4wnXY
So wasn’t it a “GM” plant that was producing the “Allison” 1000 that is being shut down? Meaning an Allison plant was not making the previous 6-speed either.
James, this article has one goal: stir the pot of ignorant consumers.
The Allison 1000/2000 series of transmissions were built in an Allison facility in Indy.
Chevrolet to Offer 10-Speed, Fully Automatic Allison Branded Transmissions in 2020 Silverado Class 2/3 HD Trucks
From what I recall GM owned Allison until the 2009 crisis. GM kept the rights to the Allison 1000 and it appears the transmission was designed with Allison corp engineering but being built at GM.
Being a GM truck owner since 1978 & having had 14 new HD trucks I can say that the 4L80E was the best automatic transmission I owned until the Allison . My first experience with the Allison was in 2005. I was disappointed with the shifting until a long distance trucker told me to change the transmission fluid to Allison’s Transynd fluid. After the change it was like a different transmission. The shifts were smoother and the transmission temperature was 10 degrees cooler. Since then I have had two Duramax Allison combos. A 2005 C5500 34’ motorhome with a 5-speed and a 2007 Chevrolet 2500HD Classic with a 6-speed. I put Transynd in both and have had no problems with either one. The motorhome has 65,000 miles of towing a 24’ enclosed race car trailer to the racetrack. The 2007 Classic has 127,000 miles with about 1/2 with heavy construction trailers behind it. This is in the hottest weather in the southwest . The Classic is the best truck I have owned. Others must think so since I get notes left on it in parking lots wanting to buy it. My first 4L80E was exchanged by Chevrolet at 36,000 miles to check wear on hard working truck towing in our high temperatures of Arizona. Chevrolet gave me an extended warranty to 72,000 miles for letting them have my transmission. I couldn’t pass having a new transmission. This showed me that Chevrolet was really trying to get it right with the new, back then, 4L80E. Only time will tell if they got it right with the new 10-speed. I’m waiting to see before I buy my next new truck. My dream truck would be an Avalanche 2500HD with a Duramax.
What I would like to know is if one of these new 10 speeds would be able to be mounted to any of the older duramax motors?
