Question members......has anyone been able to have their transmission flushed under the "drive train warranty"???? Been told by dealer that it would have been covered under the bumper to bumper (3 year now expired) but its not covered under the drive train....cost is about 300 bucks and at least 2 days in the shop.

Have you tried a different dealership? Shop around, and you will probably find a different answer.

Hi mickeywc, I bought a 2015 Z51 last spring, it had 13,000 miles but over the 36 month warranty period. I had the transmission shudder, took it to local Chevy dealer in Medford, Oregon. They diagnosed it with a pico-scope machine, and did a triple flush and filled with the newer trans fluid under Bulletin 18-NA-355. There was no cost to me. hope this helps.

I have a 2015 Corvette Stingray and had the triple flush done last August because of the shudder problem. The mileage then was right around 14,400. It was covered under the powertrain warranty. I paid nothing.

At 20,000 miles mine developed the shudder. My dealer did the flush, etc. with the old type fluid, the new fluid wasn't out yet. At 38,000 miles still OK, but figure the shudder will probably return this summer. My dealer gave me the impression that this was service bulletin matter and not a warranty limited matter. I'm expecting to do a flush/fill with the new fluid at no charge if and when the shudder returns.

That would be nice if and when you need it, but most TSBs don't necessary end up waiving the cost once out of warranty. However, since yours was treated already while under warranty, your dealer might put it through.

Like this member, I had the same thing done at about the same mileage.
"I have a 2015 Corvette Stingray and had the triple flush done last August because of the shudder problem. The mileage then was right around 14,400. It was covered under the powertrain warranty. I paid nothing."

I think there may have been an unannounced recall associated with this shudder problem. See if you can get it covered under that. Good luck.

Transmission shudder should be covered under the drivetrain warranty. That is, what, 5 years or 60,000 miles?

I had my 2015 flushed under warranty with 58 mos. and 24k miles. Driveline issues are supposed to be 5yr./100,000.

You are correct! The drive train warranty is five years or 100,000 miles... Mine is up this coming June

My dealer refused to flush even though it was still in the 5 yr warranty period, told me it was running and GM would not authorize if running; said if not running (towed in) they would flush. Out of disgust I traded it off at a considerable loss since I had upgraded/modded many items. This is not the only issue I had, just the final straw.

My dealer said they never heard of the of the shudder or the rear end problems when i took my new 2019 C7 to have shudder and rear end warble checked. So i told them make me a offer and they paid about what i paid for it back in May. They never did anything with the car and had it for sale 2 days later Just was not gonna deal with problems on a new car.

Sounds like a contact with GM would be in order and certainly a call to other dealers. My triple flush was done by one of my local dealers under the 5 year powertrain warranty at no cost to me. When I had mine done there was another one up on a lift for the same thing. They had done many of them. Call around to see which dealer has the most experience with this procedure, and take a copy of the service bulletin with you.--Bob

I got rid of the car 2 weeks ago. Used C7's are selling like crazy since all the mess with the C8. I am done with fast cars for a few years. I can't think of one car i want to buy. Mustang GT does nothing for me since i had a 2015. Used C6's are over my 7 year limit and ticking time bombs with the gas tank leaking problem over time. C8's are priced way too high. I figure in maybe 3 years i can get a used C8 for around 55k. Hell cat is too big and pricey.
