So in the past I was told never to change the tranny fluid if the vehicle had high millage and the tranny fluid wasn't changed before.
Reasons being it could cause more problems than good if you did.
I also read in a recent post on this site that you shouldn't if it wasn't maintained before. It started making me wonder if I should change mine or not. Right now, my tranny fluid is not new looking (bit dirty, still somewhat clear red looking), but its also not super dirty brown.
It worries me that if I did change it, I could be creating more problems.
Whats everyones thought on this? 04 with 241000k. (kms, not miles) Shifts pretty smooth under slow acceloration, but you can feel it change gears under a heavier load and acceloration.
