Hi All

I am having a issue with my transmission. It started as a leak and my mechanic said it was the pan gasket even though I told them about the leaking connector issue, so they changed the gasket and installed new filter and fulid so now the car runs fine but still has a leak, so I bring it back and they checked the transmission connector and the o rings are bad so they changed out the connect. so now there is no leaks but I have an issue with the transmission around 20-30mph it shutters / lags seems like your driving a manual shift and you shifted to soon only happens after the car has warmed up it wont happen when I take it for the first drive in the morning. So I have been searching and it seems it may be the TCM any suggestions? anyone have one to sell? this is driving me crazy.
Thanks in advance.

Tony
