My new Denali is at stage 3400 to be produced the week of 9/8/14.
It is almost assured to come with a 6 speed (MYC) transmission and in just a few weeks the same vehicle will come standard with an 8 speed (M5U). This will be the new standard transmission for L86 engine vehicles. However, it is almost assured that these early 2015’s will have a decreased value because of this very significant change. So by the time I take delivery of my new Denali it will already be out of date. When GM makes this significant of a change to an already in production year vehicle, there should be some compensation or rebate to early buyers. -

@bondo when did you order the Denali?

“Almost assured” needs to be addressed.
Have you gave them a demand?
Have they told you one way or the other?
Are any options being offered to you? -
-
Yes it seems unfair but what can we do about it? Nothing. If I was ordering one now, I’d cancel my order til I knew I’d be getting the 8 speed. GM jacked the price for the 6.2 which shows it includes the 8 speed. 2014 owners put these trucks on display, now later buyers get a better equipped vehicle – kinda sucks doesn’t it. Oh well.

This is the new reality of the new automotive industry. It’s not exclusive to GM.
As having the freshest products become more important from a competitive standpoint, everyone will begin making changes and updates to vehicles in the middle of a model year (called slipstreaming).
My take: GM Authority had a whole write-up and several takes on when the new 8-speeds wouid land. I don’t want to say that you should have been following and known better… but you shouud have been following and should have known better. And @bondo shouud expect to pay less for his Denali than those will get an 8-speed unit. Now, maybe he wants to pay more and get the 8-speed. This is up to him.

@bmfk how hard are you driving that poor truck? I’ve never heard a GM tranny clunk, and I ger very good economy from my 2014 Silverado with the 5.3 L83.

Related to this topic. Can anybody suggest to me why on this late date of October 2014 GM does not promote Eco Tec 3 engines and drive train options as being available for order on any of their 2015 pick up trucks ? Is this simply and inventory issue with excessive older Gen 4 V-8 engine stock or a deeper issue with design and production ramp up of Eco Tec3 L86’s ?
Maybe we have a secret member from the North Tonawanda, NY engine plant that can give an anonymous answer. -
The small availability of the 6.2L L86 V8 has nothing to do with the EcoTec3 engine line or its production. It also has nothing to do with the outgoing inventory of GMT900 vehicles.
The problem has to do with the availability of axles. The main supplier for the units made a bunch but with a defect, making them unusable. Now it can’t sell those and doesn’t have the money to make new ones. GM is working with that supplier as well as the secondary one for the axles. All should be resolved by November or December.

@ScottV503 that’s a possibility. Although it wouldnt leave the factory without the axle… but from that status, if sounds like it’s still it at the plant.
-
Chris,
Is this axle issue the reason my 2015 Sierra with 6.2’s TPW was moved from 1/5/2015 to 2/16/2015? I called GMC’s customer support line as did my dealer and we both received the same response “We aren’t sure at this time why it was delayed” and “call back next week”? I understood the January date with having a 5+ week restriction on the L86 option when I placed the order in September with the up coming holidays but it was slightly upsetting to have it delayed another month and a half and to get no explanation.
-
@dcclark7 although it could be something else, it’s likely that the axle availability issues are to blame. I feel your pain. Hang in there – it will be worth it when you finally do get the truck because they are that good.

I have a new 2015 Denali. It’s loaded with everything I wanted. Now GM wants to ruin my dream suv purchase. I think I should have bought another Cadillac. I think the change in this model is very unfair to the original owners that ordered the 2015. I have two Cadillac’s one XLR for the wife and I have a Esclade. If they are not going to do some sort of rebate. I will sell all my Chevy cars right down to my 68 GTO. They don’t care about the customer.
-
“They don’t care about the customer.” Well, that’s correct; but, guess what…you’re not their customer. The dealer is their customer, not you. There you have it…a built in way to ignore an issue when it is inconvenient to fix the problem. GM will brush the problem off to the dealer. You think you’re a GM customer, so you debate the issue with GM (who doesn’t give a hang) and the dealer has a nice day because you’re bugging GM rather than Mr./Ms. Dealer.

I purchased a Yukon SLT in last June and knu the 8speed was coming sooner or later. I had a choice not to buy the ’15.. and wait til the ’16.. but bought anyway. I am as happy as a pg in slop especially since I tuned the vehicle to eliminate Torque Management, and Electronic Throttle delay. Quite frankly I would have held off on the 8speed anyway until the ’17.
Bottom line is that buying a first year GM vehicle, with as many augmentations and upgrades they do these days from year to year is a buyer risk IF.. having the latest new thing is your bag. To add to that I also bought a ’14 Stingray Z51 M7 in Feb. I missed out on PDL, and had I wanted an 8Speed Auto (which I wouldn’t in a Sports car)I would have had to pound sand and trade. Turns out buying in GM saved me about $4000 as they raised the price a few days after I bought

I ordered my Denali 8 speed 6.2 sept 24 and almost exactly 6 weeks later it came in.
Tell you what order a 2500 denali diesel and I’ll trade you and pay difference.
This truck is a POS.
When you accelerate from a stop there is a clunk from front end that is intermittent. Dealer says I may want to take it to who did the 2.5″ level kit. The same place dealer sends their trucks to get leveled and lifted and the same brand. I just took it there myself so I could have truck a few days earlier.
There is also a shutter in the motor at 4000 rpm that you can feel and hear. They said they don’t feel it.
I ask them if there is an update or any change they can make to transmission for the horrible shift points and pressure.
No
It feels like it’s gonna fall apart or blow up when you get on it to pass someone.
The 5.3 has more pep than this garbage. Especially with their higher gear ratio.
Gotta go this morning 10 am to pick it back up, and I can see how many more scratches and swirls their detailer put on it.
Oh yeah, paid for a package to coat leather and front end for bugs and stains. Kinda like a insurance for love bug season down here. 3 times it took them to do it right. Detailer gave it back and you could see blotches on leather where he didn’t coat whole area. Back of headrests looking like it was running down and he never even wiped it. 50,000 truck and it looked better without the coating or even straight from factory.
I’m starting to think my dealer is just an oil change shop.
And to make it worse they say a simple and conservative aftermarket tranny tune will void warranty.
Shoulda stayed with ford or bought the duramax , their only decent product.
It wouldn’t be so bad if they would just fix the crap instead they look at you like your crazy and never driven a vehicle before. Like we are supposed to be amazed at the technology.
Don’t they know there are comparison trucks so we know how one feels and all.
Bottom line is 6.2 8speed 342 gears sucks. Sluggish needs tune. Hell I coulda got a raptor for this money. -
I agree with Chris. There WERE write ups about the 8 speed tranny coming. You should have done some homework. As far as the mileage on the window sticker goes, come on, guys! We have known for how many years now that the EPA mileage rating is nowhere near reality? God knows you didn’t buy a full size V8 vehicle for it’s great mileage.
What I want to know is, why is the 6.0 engine still the default on 2500 and 3500 Sierras while the 6.2 is now offered as the engine upgrade on the 1500 Sierra? I’ll bet ya THAT baby gets about 8 miles to the gallon!
