Where is the transmission control module on a 2500 2002 dodge ram with cummins?

On a 2002 Dodge Ram 2500 with a Cummins engine, the Transmission Control Module (TCM) is typically located on the driver's side of the transmission. It's often mounted directly to the transmission case itself, but it could be on a bracket nearby.

However, the exact location can vary slightly depending on the specific transmission (e.g., automatic, manual) and any aftermarket modifications. The best way to locate it definitively is to:

1. Consult a repair manual specific to your year, make, model, and engine. A factory service manual will show you precisely where it is.

2. Use a wiring diagram. Tracing the transmission's wiring harness should lead you to the TCM.

3. Search online forums. Search for "2002 Dodge Ram 2500 Cummins TCM location" on forums dedicated to Dodge trucks and Cummins engines. Someone may have already posted pictures or descriptions.

Remember to disconnect the negative battery terminal before working near any electrical components.
