I have a 1995 eagle talon esi 2.0 automatic transmission. I be driving along and when I hit the 35 to 40 mph. Its wants to downshift and not upshift. I pull over kill the car, start it back up and it shifts fine. Please give some tips. I have already tried cleaning the groung to the transmission (just replaced cable). It helped my friends same problem but in a Dodge. Please Help!
