lock up question


May 25, 2001
i have a question on lock up.i have no power going to the transmision can i run 12 volts to the tranny with a kill switch? and what do the other wires do the ones that go to the valve body
The terminals on the connector are labeled. They are as follows: A-12V, D-ground. B goes to 4th gear pressure switch and C goes to 3rd gear switch.

The 12V source is 'key-on' and normally runs through the brake pedal switch. The computer recieves signals from the two valve body pressure switches.

The TCC solenoid is normally activated by the ECM, or an added switch, grounding terminal D.
