Automatic Transmission "thump"?

Have you taken it to the dealer? Have them look at it?

i let the dealer do the fluid change since i don't have the specific tools to preform that since it's a sealed system and you gotta drain, fill a little, run it, fill a little, run it, etc...

i never ever let the dealership touch my car. well except the warranty steering lock they replaced. obviously couldn't do that on my own lol

i think it's fine since it seems like an issue with the ECU downshifting it at the wrong time causing the thump. when i shift the car down into 2nd there's no issue at all.

if something gets worse then maybe i'll have it checked out but not by a dealer.

yes the ECU and TCM are both tuned but that was a few years back so i feel like that's not the issue.
