Automatic Transmission Torque Converter problems of the 2017 Chevrolet Camaro

Had a torque converter shudder which was fixed by updating to new gm fluids. After this service, around 1000 miles later I started experiencing hard shifts from 1st to 2nd gear. Took it into service where they changed a valve body. This got rid of my hard shifts for about 1500 miles, then it came back even worse. These problems occur when the car is in motion(usually under slow acceleration).

Torque converter shudder, hard jerky shift . . Vibration around highway speed,vibration goes away when let off gas pedal. . . Lagg in acceleration around when car is already in motion. . Had the transmission fluid flush 3 times with my local Chevrolet dealership. . . They said theres nothing going can do anything to fix it if theres no code indicating that something is wrong. . By the time it throw a code either the transmission or the torque converter fail.

Hello! I want to report gm on the infamous 8l45 transmission shudder. I have had the fluid changed in 2018, the torque converter changed in 2018, and the fluid flushed with the na-18-355 bulletin back last year. Although the shudder hasn't returned. I don't trust that this transmission shows quality. I worry that this will last until our warranties are up and we're on our own. This not acceptable. This is a weak point of this amazing car. I had rough shifting and I've had shifts that bucked. This is not safe. This should be a recall or gm should give everyone a longer warranty on these transmissions.

Takata recall I just purchased the Camaro it has 48 k miles and seems like the torque converter is trying to pass the transmission I have took it to several places to get it looked at and they keep telling me it's normal but there is nothing normal about a car that sounds like its about to break apart especially not this new I'm am about tired of the car and noone wanting to fix it even doh I have factory warranty on it and even extended warranty thru silverrock I have seen where many are having this problem with the transmission on these cars and noone wants to do anything about it.

My car has been having a lot of vibrations, sputtering, rumbling while driving. Especially when speeding up. It happens while in cruise control also. I took it to be serviced and they said it was the torque converter. They flushed the system and said it should clear up after 200 miles with the new fluid they replaced. I took it back because it has been over 500 miles and is still happening. I was told all they can do is replace the fluid again for now until they fix the problem. Why are they not able to replace the torque converter now before it causes more intensive damage? I am afraid as it gets worse I will be broken down on the side of the road with a car that is in worse repair than it should be.
