Automatic Transmission Shift Mode Switch – Volvo (31481452)

Automatic Transmission Shift Mode Switch 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 Shift Mode Switch 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.

The Shift Mode Switch in this listing carries part number 31481452 and sits in the Sensors & Switches category. The number stamped on the original part is the only reliable cross-reference.

This is genuine VOLVO stock, supplied for the Shift Mode Switch with the manufacturer number intact so the reference on the box matches the catalogue.
