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 your vehicle to your GM dealer service department and have it repaired as soon as possible.

Change the fluid and filter at the intervals listed in Additional Required Services , and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants .

Notice: Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle's warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants .

After the transmission fluid has been changed, the Change Trans Fluid message and the transmission fluid life indicator must be reset. To reset the message and indicator, use one of the following procedures:

Base Audio System

Press the CLR (Clear) button located to the right of the DIC display to acknowledge the CHANGE TRANS FLUID message. This will clear the message from the display and reset it.

To reset the transmission fluid life indicator, use the following steps:

1. Press the up or down arrow on the INFO button located to the right of the DIC display to access the DIC menu.
2. Once the XXX% TRANS FLUID LIFE menu item is highlighted, press and hold the CLR button.

The percentage will return to 100, and the transmission fluid life indicator will be reset.

3. Repeat the steps if the percentage does not return to 100.
