Transmission Control Module Bracket – GM (84497083)

Transmission Control Module Bracket 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 Bracket 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.

Reference number for the Control Module Bracket: 84497083. It is filed under Transmission Control, and it is the number that has to match the part coming off the vehicle.

This is GM dealer-sourced stock rather than an equivalent, so the number on the Control Module Bracket traces straight back to the manufacturer.
