CTS V6-3.2L VIN N (2003)
Fluid - A/T: Testing and Inspection
TRANSMISSION FLUID LEVEL CHECKING PROCEDURE
1. Start the engine and allow the engine to idle until the transmission fluid normal operating temperature has been reached.
2. Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK
range.
3. Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range.
CAUTION: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission
fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any
lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the
oil fill opening.
4. Remove the transmission plug.
IMPORTANT: The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.
5. Check the fluid level. The fluid level should be even with the bottom of the threaded plug hole.
6. Add DEXRON III automatic transmission fluid in increments of 0.5 L until the fluid drains from the plug hole.
