My 2018 Camaro RS clearly has the usual transmission issues, convinced the dealer to changed the trans fluid but none of the 5 dealers I went to say it’s bad enough to fully fix the issue. Anyway I was driving on the highway, pretty aggressively and downshift a few times. When I got home I checked my trans fluid temp and it was at 210 and my oil temp was about 225. Are these normal readings cause my shudder was at its worst and the transmission didn’t know what gear to be in at all. I’m at 55k miles and contemplating trading it in if they won’t fix it before 60k.

Has long has the shudder been going on? The highest I've seen my trans temps reach was about 200, and that was in a traffic jam on a 90 degree day

I got the car with 42k and I had no issues with the transmission. Now at 55k and its progressively gotten worse since 50 miles probably. It slips a bit the first few shifts when cold and then is super delayed once it heats up. Hoping it just fully goes before 60k lol.

There is a service bulletin (18-NA-355) that should be covered under your powertrain warranty. It specifically addresses the A8 shudder. I'd call your dealer

The friction material on torque converter clutches might be damaged if it slips a lot, especially if it's getting progressively worse. I'd find out if the 18-NA-355 fluid flush had been done before you purchased the car, and if yes, push for a torque converter replacement. That plus the new fluid is expected to solve the problem for good.
