Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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. Add appropriate fluid as necessary. See RECOMMENDED FLUIDS .
