Shift Interlock Solenoid – GM (88963458)

Shift Interlock Solenoid 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 Shift Interlock Solenoid 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 Shift Interlock Solenoid is listed under part number 88963458, filed under Starters & Alternators. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

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.
