Corvette Eight-Speed Transmission Production To Start In Ontario In Q2 2022

Production of the mid-engine Chevy Corvette C8’s eight-speed dual-clutch transmission will begin at the GM St. Catharines plant in Ontario, Canada in Q2 of the 2022 calendar year, GM Authority has learned from sources familiar with the matter.
Earlier in November, GM Authority reported that the GM St. Catharines plant would manufacture the Chevrolet Corvette C8’s eight-speed dual-clutch transmission following ratification of a labor contract between General Motors and Canadian labor union, UNIFOR. In order to produce the C8 Corvette eight-speed dual-clutch transmission, GM will invest $109 million into the GM St. Catharines facility. The money will also go towards support for “continued V8 engine production.”
Also known as St. Catharines Propulsion, St. Catharines Powertrain, or St. Catharines engine plant, the GM St. Catharines plant first opened in 1954, and is located in St. Catharines, Ontario, Canada. The facility also produces the GF6 six-speed automatic transmission, as well as the naturally aspirated 5.3L L84 V8 gasoline engine and naturally aspirated 6.2L L87 V8 gasoline engine.
Going forward, General Motors will take over production of the mid-engine Chevy Corvette C8’s eight-speed dual-clutch transmission from Tremec. Based in Wixom, Michigan, with production facilities in Mexico and Belgium, Tremec is the current manufacturer of the Corvette’s DCT.
As a reminder, the C8 Chevy Corvette is offered with two engine specs, including the naturally aspirated 6.2L V8 LT2 gasoline engine, which is equipped by the C8 Corvette Stingray, and the naturally aspirated 5.5L V8 LT6 gasoline engine, which is equipped by the C8 Corvette Z06. Both models are equipped with the eight-speed dual-clutch transmission, and both ride on the GM Y2 platform. Both vehicles are also assembled at the GM Bowling Green Assembly facility in Bowling Green, Kentucky. The C8 Corvette Stingray is available now, while the C8 Corvette Z06 will go on sale in 2022 for the 2023 model year.

Tremec has had a known problem with the DCT since before launch of the C8. That’s why gm is bringing production in house. gm has regretted their decision to award DCT manufacturing to Tremec. Too bad it’s taken this long to make the production move.
The big problem that I am aware of was the insufficient production rate, causing the BG line to halt several times. They have had a few quality gotcha’s with leaks and shifting actuators failing. Not surprising, considering the brand new design.
Mine shifts flawlessly like the vast majority, and with 6,500 miles on it, should be over the infant mortality phase.
Looks like GM is moving some assembly plants out of country, there goes “Made in USA” out the window, more lost jobs for UAW and American workers. 😠 I’m sure members of the UAW are really excited about this move…. NOT
Moving? This plant has already been in Canada for decades, along with several other GM plants.
Maybe if the UAW wasn’t so greedy and driving up costs they wouldn’t have to look elsewhere for production to save money. Vehicle prices are already getting out of hand and expensive labor costs only inflate that. This isn’t the 20’s and 30’s where pay is horrid and working conditions are dangerous, unions in many cases need to bite the bullet as they have become money grabs that whine when jobs leave partially of their own doings…
Lmao this is the funniest thing I have seen on here all week. Did you mean to say If gm corporate wasn’t so greedy? I mean common sense would tell you the corporate pigs are the greedy ones or did you not realize they all wear penny loafers?
Yes, everybody beats up the unions instead of corporate and share holders. The entire world of building stuff and selling stuff would be fine Without corporate suits. And the World could do well without stock market goons filling their bellies building generational wealth for great grandchildren .😉
Sorry, isn’t this a sort of base features of capitalism? The corporate officers have a responsibility to maximize profit from the available capital for the share holders. The corporate contracts generally strongly encourage the maximization of share value with pay and bonuses.
What would you suggest to encourage consideration of the “greater good”? There have been many suggestions and attempts in the past, inclusion of the employees in the share holder set, efforts to extend the time horizon of corporate compensation etc.
Suggestion stop paying people $40 million a year salary it’s common sense it’s not that hard to figure out.
I hope they have a better trans, than their 2015 8-speed trans!
You know c8ron that Canada is a major market for GM vehicles right ? I have a 2021 Sierra AT4 and have had 10 pick ups, Tahoes etc etc. When I read a post such as yours I think maybe it is time to try something else. We are not Mexico and we actually buy these things. So how about a little love for your friends on your northern border. I will even say please and thank you!
eh?
How about ‘uhh’ Mr. American. Lived down there 10 yrs. and know you guys all to well. Come on up here and learn something about Canada.
If the parts work without the problems currently being reported, I don’t care where it is assembled. Maybe farming out the DCT to Porsche would have been wise.
WAINE HERE .. I HAVE 2010 TERRAIN 143000 MADE HERE IN CANADA .. WHERE IT SHOUD BE .. RUNS AS GOOD AS THE DAY I BOUGHT IT . MERYCHRISTMAS CHEERS ,
As a fellow Canadian, I have bought GM products for years. I currently own 3 GM vehicles and love them all. 2017 Camaro, 2009 Pontiac G8, and 1980 Grand Prix LJ, all bought new, and all in perfect condition. TeeKay is saying it like it is.
What has Canada done for us? Justin Bieber?
We’ll send em Brandon in exchange for Bieber.
You Daniel, are an ignorant jerk. Thank god all Americans aren’t like you. Lived there 10 yrs., and know what I speak. By the way, I do not like Bieber.
“the C8 Chevy Corvette is offered with two engine specs”
Since GM is not yet accepting orders for the C8 Z06 / LT6 engine – this is not quite accurate – yet.
C8 Z06 is for the elite 1 percenters. Getting one will cost big bucks !! ADM thru roof !!!
So, by bringing the DCT assembly In House, the tranny failures will stop ? Along with the question of how much oil it should really be filled with, the ridiculous method required to add extra oil, etc? It’ll still be Tremec parts, design, assembly methods, and engineering.
Then, GM will attach them to a more powerful engine with the Z06 ! Like McDonald’s says:
“I’m Loving It !”
The LT6 generates less torque than the LT2, although at a higher RPM. The gears and structure are more sensitive to torque than moderate changes to rotation speed, assuming GM and Tremec have done their modal analysis correctly (no resonances).
As we can all read, the Corvette C8 8-speed DCT will be built by GM Kananda in the future. So now a GM internal production. That’s a good thing, and GM now knows all the component data and can make changes at short notice if necessary. It is also called best quality!
Who built my 2014 6.2 engine with bad valve springs? Mine exploded with 17000 miles on it last month going 15mph…..cost me $18,000 for a new engine. Horrible gm quality and gm customer care didnt care…c8 has tge same issue.
18K? where were you shopping? A replacement long block is $3K and installing it is $2K in most shops, Its a 2 day job.
Parts break sometimes, if you cannot afford to fix it, have insurance to cover it.
Trivial matter – but it counts – you misspelled St. Catharines several times in the article and correctly other times. You bounced between “Catharines” and “Catherines” – the first is correct, the latter is not.
Anyways I am glad for GM to produce such a nice car and also for the people of St. Catharines Ontario who will be proud to produce it.
Thank you for calling that out. The post has been updated.
I know this is old news but………GM can move the manufacturing where ever they like. This wont change the fact that the TR9080 is garbage,. People expect a 100K car to not need a trans every 7500 miles.
Disappointed, do you have personal experience? Please tell your story!
