Back in early March 2023, GM Authority reported that production of the refreshed 2024 Chevy Silverado HD had finally kicked off at the GM Flint plant in Michigan after its big unveiling in September 2022. Now, production of the revised heavy-duty pickup truck has commenced at the GM Oshawa plant in Canada.
In a recent social media post, GM Canada showed off a Black (color code GBA) 2024 Silverado HD LTZ rolling down the assembly line at the Oshawa plant, equipped with the Z71 package and optional 20-inch Chrome aluminum wheels (RPO code SKW). Notably, this facility is the only GM plant that currently manufactures both light-duty and heavy-duty pickup trucks.
As a reminder, the mid-cycle refresh for the 2024 Chevy Silverado HD features a new front fascia that is highlighted by revised headlamps and a new grille design, the former of which incorporates a new C-shaped LED lighting scheme. The exterior paint list also includes six new hues, and there are new wheel and tire options as well, while all models are now equipped with tow hooks as standard fare.
For all LT and above trim levels, the interior has been completely overhauled and now features a 13.4-inch infotainment screen and 12.3-inch diagonal configurable driver information center. Notably, lower trim levels will still wear the pre-refreshed interior.
Under the hood, the 2024 Silverado HD is equipped with the naturally aspirated 6.6L V8 L8T gasoline engine, rated at 401 horsepower and 464 pound-feet of torque, as standard across all trim levels. The optional 6.6L V8 L5P turbodiesel Duramax engine, which has been uprated to 470 horsepower and 975 pound-feet of torque for the refresh, is also available. New-for-2024 is the transmission situation, where both engines are equipped with the Allison-branded 10-speed automatic transmission as standard.
Under the body panels, the Chevy Silverado HD rides on a more-capable variant of the GM T1 platform, which it shares with its corporate platform-mate, the 2024 GMC Sierra HD.

Nice truck, did they make any 23’s?
Someone please report back on the performance of the fake Allison transmissions in these trucks.
I’ve owned two Duramax’s (2020 & 2023) with the 10 speed “Allison”. I have owned four Duramax’s (2014, 2016, 2017, & 20190) with the 6 speed Allison. My trucks are/were used for a combination of heavy towing, daily driving, spirited recreational sprints, etc. I haven’t had any issues with either transmission. Towing performance is vastly improved with the 10 speed.
Good, I am glad the quality has remained without the true Allison transmissions. Thanks.
It’s as Alison as the 6 speed, or do you not know that the 6 wasn’t built in an allison plant but in a facility that GM built and staffed with their own employees.
The allison 10 was GM took the 10l90 across the street to allison and said “bulletproof this” allsion engineers tweaked a few things, beefed everything up and sent it back. It’s as allison as your going to get unless you plan on taking the transmission out of a striker assault craft that was handmade one at a time at the actual allison R&D center.
True, the Allison series 1000 6-speeds were assembled in a GM factory in Baltimore after GM sold Allison Transmission Div. in 2007. That factory closed in 2019. GM then designed the current 10-speed and had it tested and validated by Allison in order to retain the brand name beginning with the 2020 model year. Given GM’s recent history of transmission problems it’s good to know this one is doing well. Maybe Allison should test and validate all GM automatic transmission designs.
I have over 70k miles on my ‘20 Chevy 2500HD, maybe 20k pulling an 11k Pound gooseneck. The transmission so far has been flawless. And the so called “fake” Allison is the only automatic transmission GM has put in a truck that can legally pull a 35k pound trailer.
Glad to see gm Oshawa plant still building trucks and people working in oshawa keep the tradition going building vehicles in Canada and the U S !!
I’ve had GM, Ford, and Ram. I bought a 2020 and absolutely loved it. Pulled a 15k pound 5th wheel like it wasn’t there. Just bought a 2023 Denali. Zero reason to consider Ford SD or Ram. The “fake” transmission is an amazing piece of engineering.
The Allison 10 speed is not fake… It is illegal for GM to use the Allison name on something that is not GM’s product! In such the same way that Dodge can not say that the Cummins is an Chrysler product… That’s called STEALING OR falsely use another brands name on your product GM would be in court if that where the case. Anyway nice looking truck.
Sorry, fake was probably not the best word use however it is a GM transmission that has been tested and validated by Allison, but not an Allison since 2019. Many don’t know that. Glad to hear they are performing well. You can still get a true Allison in a 4500-6500 Chevy truck.
Good vehicle
Maybe they’ll start building the Special Editions now!!
I see a black bumper behind the first truck!! That’s a Midnight Special Edition!! Let’s get the Z71 Sports Edition going!!!
My z71 sport was accepted last Thursday. TPW of 4/24
Kent, that’s awesome!! Hopefully I’ll get mine excepted soon. Anyway, what is TPW?
I hope yours shows up soon. TPW – is the targeted production week.
Thanks!! I’m hoping I get it before summer. I’d like to pull the camper with it before I have to put it away for the winter! Lol
Ordered a High-Country Durmax Midnight Edition Feb 28, still no update from the dealer. Maybe June delivery ?
Having closed the Oshawa truck plant in 2009 and retiring from Oshawa in ‘15, this is good news for a lot of young people. Unfortunately this article is just an ad for the truck. How about talking about the impact it has on the local community and suppliers. How many jobs were created? What’s their production count? I can see why Oshawa is building trucks again though. Between 1985 and 2005, the Canadian $ was running between .64 cents and .72 cents American. We were building 450 trucks per shift on 3 shifts. The amount of profit GM was making on 1350 trucks per day was incredible!! We also had to construct shelving units just to hold our J.D. Power awards for quality and productivity. Dealers always wanted Canadian trucks.
I wish Oshawa built all our Silverados for Canada seeing as the investment that the provincial and federal government made with GM. Unfortunately I still see lots of light duty Silverados coming here with VIN #’s starting with a “3”? Shame on you GM I will never buy a vehicle from you till this is Corrected!!
