How to repair a power relay in a TCM?

Connect the meter between the TCR control terminal on the TCM and the relay control terminal in the fuse box. The meter should read a numeric value. If the meter read out of limits (OL) there is an open circuit. Consult the factory wiring diagram and repair the power side of the circuit as necessary.

What happens when the Transmission Control Relay is 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”.

What are the symptoms of a car in limp mode?

Common symptoms of limp mode include: 1 Reduced power 2 Speed limited to 40 MPH. 3 Engine revolutions limited to 2000 or 3000 RPM. 4 Transmission won’t change gears (Stuck in 2nd or 3rd) 5 Very slow response when pressing the gas pedal 6 Check engine light on or flashing. 7 Engine may overheat

Where is the Transmission Control Module ( TCM ) located?

The relay is controlled by the powertrain control module (PCM) and/or transmission control module (TCM). Depending on the application, the TCR may be located in the intelligent power module (IPM), which is basically a smart fuse box, or in a standard fuse box.

Can a clutch pack fail on a Chrysler?

The clutch packs do not fail (unless ran low on ATF, or pre ’93)These always have hard part failure (plantary gears, 2/4 hub and others. Unfortunatly its sounds like there are some people in your area that don’t know electronics very well.
