Guest Fozgood Posted May 6, 2012 Share Posted May 6, 2012 Trans was running fine. Now when engine is hot I can't shift into reverse without the whole car starts to jump. After car cools I can put it in reverse, but not when it is hot. No sounds, no grinding, no slipping, ......Any ideas before I start taking things apart that I don't have to?Thanks,Brian Link to comment Share on other sites More sharing options...
old-tank Posted May 6, 2012 Share Posted May 6, 2012 BrianThe first things to check are the engine and transmission mounts and thrust pad.Willie Link to comment Share on other sites More sharing options...
60FlatTop Posted May 6, 2012 Share Posted May 6, 2012 Make sure the transmission fluid is not overheating and causing this problem, I thinking Dynaflow.A few years ago a friend asked me what would cause transmission fluid to blow out the fill pipe and cover his engine. Prior to that they had addressed a cooling problem with a re-cored radiator, new water pump, belts, and hoses. In the end his problem all along was dragging brakes.Bernie Link to comment Share on other sites More sharing options...
Guest shadetree77 Posted May 8, 2012 Share Posted May 8, 2012 can't shift into reverse without the whole car starts to jump.My '52 with Dynaflow started doing that very same thing. If I didn't hold the shifter down while in reverse, it would jump back and forth between Low and Reverse rocking the car the whole time! Willie told me to check the mounts and the thrust pad and I'm 99% sure that is the problem. Definitely start with those. Link to comment Share on other sites More sharing options...
