I have a 1995 f150 and my overdrive light keeps flashing and the trans has delayed/hard shifts. It sounds crazy but it seems to only happen when it's hot in the cab ( after heats been on for a while in the winter time or on hot summer days before the ac cools it down) I've been fighting this issue for a while but haven't figured it out. One day out of frustration I hit the dash above the steering wheel and the flashing stopped for a while but started again the next day, any advice or tips would be greatly appreciated 👍
