Part throttle trans slippage
Have a 2000 3.0 auto 4x4 and seem to be developing a part throttle trans slippage. It usually occours when the throttle is lifted and a very gradual increase is applied. Seems to be in second or third when it does it. WOT seems to be fine and pulls,,,well pulls as good as a 3.0 can. Any thoughts or is it just going south. Trans fluid was swapped within a year and it doesn't smell at all. 165k miles on truck.
