Transmission Control Module Bracket – GM (84522146)

Transmission Control Module Bracket converts a physical condition into a signal the powertrain module acts on. The module compares that signal against an expected range at every start-up, so a failing unit is usually logged before it becomes a driveability complaint.

Replace the Control Module Bracket when the fault repeats with the harness already ruled out, when resistance drifts as the part heats up, or when a connector has corroded past cleaning. Swapping a sensor to chase a wiring fault is the most common wasted repair on these circuits.

For this Control Module Bracket the reference is 84522146, in our Transmission Control range. Compare it with the number on the part you are replacing rather than with a photograph.

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genuine GM, and this Control Module Bracket keeps the original engineering number, which matters once a number has been superseded more than once.
