hi just came acrooss this thread. I just had my tranny rebuilt which cost me 1500 problem i am having now is when upshifting from 3-4 and downshifting from 2-1 there is a hard shift and a bang. this is a intermittant problem and brought the car to the mechanic 4 times until he actually felt it. it comes and goes and can last days sometimes then go away for a week.

the mechanic said its a pressure solenoid. did your car do this? also he said this wasnt changed in the rebuild, is it supposed to be?
