When you take your vehicle to your local GMC dealership for transmission service or repair, you're also getting 100-plus years of automotive manufacturing experience and expertise. Our Certified Service expert technicians receive exclusive factory training and know your GMC vehicle and transmission better than anyone. When it comes to transmission replacement and transmission repair service, they can offer you a transmission from our Genuine GM Parts brand.
If there is a transmission issue that requires immediate attention, the Driver Information Center may display one of the following messages:
This message displays if there is a problem with the transmission. See your dealer for transmission service.
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).
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.
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. Contact your dealer for additional information. 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.
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.
