Overdrive Solenoid-PCM Pin #55

Electrical Connections At Transmission:

DESCRIPTION
This circuit controls operation of the transmission mounted overdrive solenoid used for overdrive operation.

OPERATION
The Powertrain Control Module (PCM) will determine when to engage and disengage the solenoid by monitoring engine RPM and vehicle speed, versus output voltage of the throttle position sensor. Also needed are various inputs from the module timer.
