Laymans terms

This code means there's a problem with the part of the car that lets you manually shift gears in an automatic car. It's like when a remote control button stops working.

Explanation

The P0950 code is triggered when the powertrain control module (PCM) detects a malfunction in the circuit that controls the manual shift function in an automatic transmission.

Technical description

The P0950 code indicates an issue with the electrical circuit responsible for the manual shift control in an automatic transmission. This system allows the driver to manually select gears using the gear lever or paddle shifters. A fault in this circuit can prevent the manual shift mode from functioning correctly.

Symptoms

• Check Engine Light is on

• Inability to manually shift gears

• Transmission stuck in one gear

Common Causes

• Faulty shift lever assembly

• Damaged wiring or connectors

• Defective transmission control module (TCM)

Glossary

PCM: Powertrain Control Module

TCM: Transmission Control Module

Diagnosis steps

• Check for any other related trouble codes.

• Inspect the shift lever assembly for damage.

• Test the wiring and connectors for continuity and damage.

Repair procedures

• Replace or repair damaged wiring or connectors.

• Replace the shift lever assembly if faulty.

• Reprogram or replace the transmission control module (TCM) if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Screwdriver set
