Checking Fluid Level: Transmission
WARNING: This page does not describe the selected car, but rather 35 other vehicles, including the 1992 Pontiac Trans Sport, 1992 Oldsmobile Silhouette, 1992 Oldsmobile Bravada, 1992 GMC Yukon, and 1992 GMC Vandura Special. However, it is still accessible from the selected car via links, so may be relevant.
With vehicle parked on a level surface and engine at idle, move selector lever through all positions, ending in Park. Let vehicle idle for 3 minutes with accessories off. Remove dipstick, wipe clean and check fluid level. Fluid level should be between ADD and FULL marks on dipstick.
If vehicle has been operated for an extended time at high speed, in city traffic, or pulling a trailer, an accurate fluid level cannot be immediately determined. Transmission must cool for about 30 minutes after vehicle is parked before fluid level can be accurately checked.
