KenFichtner@LaurelChevy

So what does this mean? Improperly torqued? to tight, cross threaded or left loose? Very confusing document. No VIN range listed. I'll wait until I am notified to do anything, until then I'm driving it. Mines an early 24. Not overly concerned about this. For them to just flat say replace the transmission means to me the bolts were cross threaded possibly or in a way that it damaged the transmission body. This transmission already has enough bad publicity and now this on models that are several years down the road. Ridiculous!

Not to mention GM doesn't even have a transmission to replace it with from what I've read here in last 6 months of being here..

According to the St. Catherines website they are now building the C8 DCT. I wonder if this has something to do with the transition from Tremec Michigan. Perhaps wrong torque tables or something.

From the document, this is a "customer satisfaction program" bulletin, not a recall (yet?). I have had a couple vehicles over the past 20 years that have these kind of programs. They don't tell you there is a problem unless you "have THE problem" and take it to a dealer service department, or happen to be at a dealer service department and ask about it if you know about it. Then they tell you that they will fix it for free because there is a silent "goodwill" bulletin. If you have THE problem after the timeframe it is active (in this case, take your car into the dealer after May 31, 2026), or missed the timeframe, in my experience, they will tell you about it and it is on your dime to have the work done/parts replaced.
It was nice of them to post this, otherwise it would have probably surfaced "someday".

Per the 1st paragraph in the TSB, it seems you can go to your service manager, or assistant service manager, and have them go into the GWM system and see if your car is classified as “open” and you will know immediately whether you need to act upon this TSB. I have sent a message to my service advisor, and expect an answer within the next 24 hours if my car is affected.

I didn't know GM and Boeing swap-out assembly crews!

I just did the same thing. Hope to have an answer in a day or so.

If you get this work done, will it show up on a CarFax saying the transmission was replaced? If so, do we care?

Glen e

when I was a general manager of a dealership and the used car department would be appraising a car, and we would pull up Carfax or warranty history and saw that a component was “replaced”, not “repaired”, we took that as neutral news -As if nothing had ever happened because we knew that the entire component was new, not subject to a poss bad technician expertise repair.

on the OP subject, I wonder what the reason is that they won’t actually publish a vin range on this? If they can go into the warranty system and stamp “open or closed” on each VIN, why can’t they give us a range?

If I had to guess, I'd say it's the late 23s and early 24s that received the "improved" DCT.

Thanks for posting Ken!!!!!

The updated DCT oil pan with baffling was done on MY23 VINs starting from 37263 forward. Mine is part of that group. I just called my service dept. and they confirmed that bulletin is a recall and that my VIN has no outstanding recalls linked to it, thus that bulletin does not apply to my MY23 C8 with the updated oil pan baffling.

Also General Motors (GM) began manufacturing the TR-9080 DCT at its St. Catharines plant in Ontario, Canada in the second quarter of 2022.

Glen e

are we saying that if you go into the NHTSA site and punch in your VIN and it shows no unrepaired recalls that we are Scott free?

or maybe it’s too early for that…..

If you're suggesting Chevy's own system isn't up-to-date, I'm making no claim on that either way. Just relaying what the Chevy service department told me. They looked it up in their system. Not sure if it's the same system we have access to. But they also did pull up the bulletin which confirms that's also in their system. So there's that.

Before I told them to look up the bulletin number, I told them it was a "Customer Satisfaction Program" bulletin. They were fighting me saying that because it's not a recall, they won't be required to do any work on my car. I told them to look up the bulletin number anyway. Then they confirmed that is a recall. That shut them up. I guess they use new wording such that recall bulletins don't explicitly spell out "recall" due to the negative connotation. The new PC phrase is "Customer Satisfaction Program."
