I have a 1989 Mustang LX Convertible. When the car is cold the Tranny shifts fine. When it gets warm and I am going about 30 to 35 mph it won't shift at all. I just replaced tranny and torque converter. When I did the swap it worked fine for a while but the problem is back. Any suggestions
U have a tranny cooler??? Check all your fluids and make sure the TV cable is set right. I don't know much about AOD's other than I have one. I have a shift kit and a big cooler and very rarely have any issues so far.
