RAM 1500 Truck 2WD V8-5.2L VIN Y (1997)
Transmission Control System Relay: Description and Operation
CIRCUIT OPERATION
Four Speed Automatic Transmission
The electronic transmission relay powers the overdrive solenoid, torque convertor clutch solenoid, and variable force solenoid. All three solenoids
are molded together.
Circuit K125 from the generator powers the coil side of the electronic transmission relay. The Powertrain Control Module (PCM) provides ground
for the relay on circuit K30. Circuit K30 connects to cavity B30 of the PCM.
When the PCM grounds the relay, the relay contacts connect circuit A14 from fuse 8 in the PDC to circuit T16. Circuit T16 powers the solenoids.
