Replace the filter again on the last drain/fill.

 

Merged duplicate threads.

 

See what 2 more drain and fills will do before going any other routes. It might have been filled with the wrong fluid.

 

I'm sorry, I couldn't figure out where my first post went, I'm new to the forum thing, thanks. I bookmarked it this time lol. I did the second drain and fill this past weekend and plan to do the third just before I goto my gf parents 6hrs away. (I hope my trans isn't gonna have a kaniption). I just wanted to know if there was anything else I might want to replace before or during the next drain/fill. I did notice that once I'm up to highway cruising speeds and it gets into its final gear and when I believe the torque converter lockup engages that if I just hold the gas where it is and push the brake pedal that the lockup does NOT disengage at all. I'm now wondering if the slipping I'm feeling is in the torque converter and not the transmission. I been fixing cars for over 25 years and I f'n hate transmissions, even more now that they are all electronically controlled throughout. I'm almost at the point of just buying a low Km used trans and just r&r ing it.
