Automatic Transmission Input Speed Sensor – GM (24269985)

Automatic Transmission Input Speed Sensor is part of the circuit that reports engine or transmission behaviour back to the control module. It is read continuously, and a value that drifts out of range sets a fault code long before the driver notices anything.

Replace the Input Speed Sensor when the code returns after clearing, when the live data reading is out of range at operating temperature, or when the housing shows heat damage. Check the ground and the connector pins first.

This Input Speed Sensor is listed as part 24269985 (Sensors & Switches). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.
