Re: transmission failure on 04 Freestar 3.9. NEED HELP
I'm a little more familiar with the old school vacuum operated in-line automatics, but the transverse pretty much are the same thing, but bent with solenoids, so I'll see if I can muck something through. The heat marks are indicative of the band not releasing when it should, given the name, I can't help but wonder if the coast servo piston is either sticking or not getting the proper signal.
At this stage, I'd look into a rebuild, either by yourself or professionally, or replacement with a used. If you do the rebuild, I'd definitely get the piston kit. If you're looking for numbers, Aamco rebuild the tranny for my Grand Prix for 1400 which included the differential, and since it's a GTP, I couldn't do it for that price. I did pull the transmission, though.
