whatsup everyone, I have a 99 gs3 with 210k miles. The trans seems to shift hard when im really getting on the gas, when im easy on the gas it shifts fine. My question is should i change the trans fluid or keep whats there, i dont know if its going to help or not.

Im hoping i dont need a new trans because thats not in the budget right now lol, thanks for the help in advance.

 

Most would say change it but don't flush it.
