Checking Fluid Levels: Transmission

With vehicle parked on a level surface and engine at idle, move range selector lever through all ranges, ending in Park. Remove dipstick, wipe clean and check fluid level. Fluid level should be between ADD 1 PT. and FULL marks on dipstick. If vehicle has been driven for extended period of time at high speed, in city traffic or pulling a trailer, an accurate fluid level cannot be immediately determined. Allow transmission to cool for about 30 minutes after vehicle is parked, then check fluid level.
