Laymans terms

This code means that the car's computer detected a problem with the fourth gear in the transmission. It's like when your bike gets stuck and you can't change to the next gear properly.

Explanation

The vehicle's transmission control module (TCM) has detected an issue with the monitoring of the fourth gear, possibly due to an electrical fault, and has engaged a substitute program to maintain drivability.

Technical description

P1732 is triggered when the transmission control module identifies an inconsistency in the expected and actual behavior of the fourth gear. This can be due to electrical issues such as faulty sensors, wiring problems, or issues within the transmission itself. The TCM may enter a fail-safe mode to protect the transmission.

Symptoms

• Check Engine Light is on

• Transmission stuck in one gear

• Poor vehicle performance

Common Causes

• Faulty transmission solenoid

• Wiring issues or poor electrical connections

• Malfunctioning transmission control module
