Transmission Control Module – GM (24222126)

Transmission Control Module 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 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 the reference is 24222126, in our Transmission Control range. Compare it with the number on the part you are replacing rather than with a photograph.

Genuine GM supplied for this Control Module, with the engineering number unchanged from the factory reference stamped on the original.
