Shift Interlock Solenoid – GM (88967140)

Shift Interlock Solenoid 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 Shift Interlock Solenoid 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 Shift Interlock Solenoid the reference is 88967140, in our Starters & Alternators range. Compare it with the number on the part you are replacing rather than with a photograph.

This is genuine GM stock, supplied for the Shift Interlock Solenoid with the manufacturer number intact so the reference on the box matches the catalogue.
