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.

While the vehicle is moving on either street or highway, the transmission vibrates when slowly accelerating and the RPM's are around 1500.

- Tampa, FL, USA

Transmission slips at approximately 1500-1800 RPM while in motion on highway causing severe vibration of vehicle. Transmission won't hold a gear and won't automatically shift to prevent vibration. Vehicle seems to 'lug' at these RPM's.

Shuttering at low speeds coming to a stop and now having trouble with the reverse once in reverse it doesn't want to shift out of it fights you big time and have to play with it to get it back to first all other forward functions seem to be fine at this time this is a 6 speed manual transmission.

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.

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).

Transmission is slipping engine surging between 35 an 60 mph.

I purchased this car new in October, 2016. My transmission problems started soon after owning it, growing worse as time went on. The car would not shift, once it did, it lurched. It would miss shifting, lag, delay and roughly drive, even though being an automatic. The dealer only serviced new software updates; all else was ignored. In early August, 2019, a service manager told me to get a second opinion. I soon discovered that GM is being sued, via class action law suits as my problems are being experienced by many others, yet they still sell new cars with this same transmission. On August 17, 2019, I traded it back in to the dealer with only 17,400 miles on it, not knowing that I would be stiffed on the trade in value. GM did almost nothing to help me, finally admitting that they know they have a problem, but no solution. I have discovered that most trade publications and media outlets have not run this story alerting the public that GM in knowingly selling cars with bad transmissions. How do I recover my losses? thanks, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).'

Takaya recall 2017 Camaro 35K miles when my car is in motion it shifts gears very hard and when I am going highway speed around 66-72 my car starts vibrating like it's about to fall apart but when I'm going down a hill at that same speed I don't have this problem.

- San Antonio, TX, USA

I bought the car new. It's been in shop 3 times already due to transmission issues. Always wanting to add different transmission fluids/flushing 18-na-355. Car has vibration and shudder at highway speed. Jerks as when gears change out for an automatic transmission. My car has low miles and very well taken care of inside and out. I do have more documentation if needed

Transmission hesitates hard shifts vibrates and shudders when accelerating. Especially noticable between 55 to 85 mph. Very dangerous when driving on highway or interstate as the hesitation during shudder may delay critical maneuvering of vehicle

The front and back windows get a film on them. We were told it was because of the leather seats. When the car has been sitting when you start the car there is a shift flare from 1st to 2nd speed. It does it one time after it's been sitting for an hour or so.

My Camaro shakes violently when the car cruises at around 1,200 to 1,400 RPM. I have taken it back to the dealer several times and have had the transmission tripled flushed. The problem goes away for a few days and then returns. The dealer says that they cannot do any more to rectify the problem, but the vibration is getting worse. I am concerned for both the safety and decreased value of my case as a result of GM ignoring this problem. The problem has been present since I purchased the vehicle in 2018.

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

Hard shifts between 1st & 2nd gear vibration between 1500 & 1800 RPM. This car has active fuel management vibration seems to happen worse when in 4 cylinder mode. GM is aware of the issue and keeps promising a fix which has yet to be released. Blame it on fluid in transmission.

- Haltom City, TX, USA

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.

When taking off from a stop, at normal speed, the engine bogs and almost stalls. This requires a re application of the clutch and more throttle to prevent stalling. This happens almost daily. It has happened while pulling into traffic from a driveway and almost caused an accident. I have been driving with a clutch for over 30 years on both cars and motorcycles. There is a real problem with the torque management system on this car. This problem affects many of this model of Camaro there is an online forum that has an in depth discussion of the problem: www.camaro6.com/forums/showthread.php?T=498180&page=10

The manual transmission bogs in first gear under aggressive acceleration from a standing start. This most often occurs when pulling out into traffic. I have had the vehicle almost stall on numerous occasions iwhen pulling out into traffic. I believe the cause is excessive torque management in the vehicle's ECU program.
