When you experience a transmission problem, it could be any number of issues. The transmission has more moving parts than many other vehicle systems, making room for error a little larger for someone not properly trained when it comes to transmission repair. That’s why you need a Certified Service expert with advanced training and GM vehicle knowledge.

If there is a transmission issue that requires immediate attention, the Driver Information Center may display one of the following messages:

  • Transmission Repair from Certified Service Experts TRANSMISSION REPAIR

Service Transmission

This message displays if there is a problem with the transmission. See your dealer for transmission service.

Shift to Park

This message displays when the transmission needs to be shifted to P (Park). This may appear when attempting to remove the key from the ignition if the vehicle is not in P (Park).

Transmission Hot — Idle Engine

This message displays and a chime sounds if the transmission fluid in the vehicle becomes hot. Driving with the transmission fluid temperature high can cause damage to the vehicle. Stop the vehicle and let it idle to allow the transmission to cool. This message clears when the fluid temperature reaches a safe level.

How to Check Automatic Transmission Fluid

It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer and have it repaired as soon as possible.

There is a special procedure for checking and changing the transmission fluid. Since this procedure is difficult, this type of transmission repair should be done at your dealer. Change the fluid at the intervals listed in the Maintenance Schedule of your Owner’s Manual, and be sure to use the fluid listed under Recommended Fluids and Lubricants.

When to Change Automatic Transmission Fluid

Automatic transmission fluid should be drained and replaced (with Dexron® VI Automatic Transmission fluid) as listed in the Maintenance Schedule of your Owner’s Manual.
