How to check the power of the Transmission Control Relay?
Remove the transmission control relay. Turn the vehicle ignition on and use a test light to check for power to the TCR. Connect the test light between the battery negative terminal and the relay control terminal in the fuse box. The light should illuminate.
What happens when the power relay is off?
When the relay is off, no power is supplied to the control pack and the transmission goes into “limp mode”. The relay is controlled by the powertrain control module (PCM) and/or transmission control module (TCM).
When is the Transmission Control Relay ( TCR ) off?
The transmission control relay (TCR) is used to supply power to the transmission solenoid pack during normal operation. When the relay is off, no power is supplied to the control pack and the transmission goes into “limp mode”. The relay is controlled by the powertrain control module (PCM) and/or transmission control module (TCM).
Where can I get Transmission Control Module repaired?
The vehicle was taken to bob moore Chrysler Dodge Jeep ram of tulsa (4627 s memorial dr, tulsa, ok 74145) and the transmission control module was repaired. The vehicle was kept at the dealer for three months. While leaving the dealer, the contact stated that the transmission indicator illuminated again. The dealer reprogrammed the vehicle.
