Automatic Transmission Input Speed Sensor – GM (24238955)

Automatic Transmission Input Speed Sensor 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 Input Speed Sensor 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 Input Speed Sensor is listed under part number 24238955, filed under Sensors & Switches. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

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is genuine GM, and this Input Speed Sensor keeps the original engineering number, which matters once a number has been superseded more than once.
