Transmission Control Module – Mopar (68446166AA)

Transmission Control Module is an electrically controlled component in the engine or transmission management system. Because the module cross-checks it against other inputs, a fault here often surfaces as a code for a different circuit.

Replace the Control Module when a value freezes or drops out intermittently, which usually means an internal fault rather than wiring. Wiggle-testing the harness while watching live data separates the two.

This Control Module is listed under part number 68446166AA, filed under Transmission Control. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

The stock here is genuine MOPAR, and this Control Module keeps the original engineering number, which matters once a number has been superseded more than once.
