GMC Terrain: Vehicle Checks / 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.
Change the fluid at the intervals listed in Maintenance Schedule , and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants.
Caution
Use of the incorrect automatic transmission fluid may damage the vehicle, and the damage may not be covered by the vehicle warranty. Always use the correct automatic transmission fluid. See Recommended Fluids and Lubricants.
There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, this should be done by your dealer.
