Transmission Control Module Bracket – GM (84406070)

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.

This Control Module Bracket is listed under part number 84406070, filed under Transmission Control. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.
