I have a 94 PCM and transmission (I think the tranny is a 94 because it only has 12 wires in the connector instead of 13...95 and up had one more wire) and have not been able to lock up the converter for a while now. I tried taking pin 11 on the blue connector (tcc lockup signal), wiring it to a switch, wiring the other end of the switch to ground to attempt to lock up the converter. It didn't work either. Does that mean my solenoid is bad? I have no fault codes or ses light from the computer.
