Laymans terms

This code means that there is a problem with the electrical circuit that helps the car know which gear you want to be in. It's like when a video game controller button doesn't work properly.

Explanation

The P1867 code is triggered when the transmission control module (TCM) detects a low voltage or signal in the Gear Selector Lever 2 (GSL2) circuit.

Technical description

The Gear Selector Lever (GSL) is part of the transmission system that communicates the driver's gear selection to the vehicle's computer. The GSL2 circuit is monitored by the TCM for correct operation. A low signal indicates a potential issue with the wiring, connectors, or the gear selector lever itself.

Symptoms

• Transmission not shifting properly

• Vehicle stuck in a single gear

Common Causes

• Faulty gear selector lever

• Damaged wiring or connectors in the GSL2 circuit

• Defective transmission control module (TCM)
