Laymans terms

This code means there's a problem with a part in your car that helps it change gears. It's like when a toy robot gets stuck and can't move its arm properly.

Explanation

The transmission control module (TCM) has detected a problem with the electrical circuit controlling the shift solenoid B. This solenoid is responsible for helping the transmission change gears.

Technical description

The P0975 code is triggered when the TCM detects an issue with the shift solenoid B control circuit. This could be due to a range or performance problem, such as an electrical fault or a mechanical issue within the solenoid itself.

Symptoms

• Transmission stuck in one gear

• Harsh or erratic shifting

• Check Engine Light illuminated

Common Causes

• Faulty shift solenoid B

• Wiring issues in the shift solenoid B circuit

• Malfunctioning transmission control module (TCM)

Glossary

TCM: Transmission Control Module

Solenoid: An electromechanical device used to control fluid flow in the transmission

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connectors for damage.

• Test the shift solenoid B for proper operation.

Repair procedures

• Replace faulty shift solenoid B.

• Repair or replace damaged wiring/connectors.

• Reprogram or replace the TCM if necessary.

Tools required
