Hey guys and girls! I need to get ya'lls opinion on if I should change my tranny fluid and filter or not. I have the 4T45 tranny just for some info. The car has almost 73k miles. The dealership I got it from has no record of the fluid and filter ever being changed. I know the owners manual says every 50k miles if you drive under one of their listed conditions. Being the car was used and I dont know if it was ever abused, would it be ok to have it changed? Ive heard if you wait too long to change it then it is better to just leave it be. Something about it can mess your tranny up with the clean fluid. So what are your thoughts? It seems to shift fine and Ive never had any problems since I bought it with 70k miles. I would hate to have it replaced and then have problems with it slipping. Thanks for your input.
