Ok, so i guess i should throw my backup c-3 away, i have one layin around in case of emergency c-4 failure, wasn't aware of any torque multiplication differences. Could that problem be in the torque conv, and not the tranny itself. dont know much about the internal workings of an automatic. I was a machinist at a transmission remanufacturer for 2 years. but I only messed with the pumps and drums and planetary's.
Anybody want to buy a C-3 for pinto $50.
