To check the fluid in an automatic transmission, the vehicle must be on a level surface with the engine and the transmission at normal operating temperature. When you read the dipstick, the engine must be running, the emergency brake engaged and the shift selector in "park". Some manufactures require the fluid to be checked while the car is in "neutral". Check your vehicle's owner's manual to be sure. Consult your owner's manual on where to find and how to read the dipstick. If you have lost your owner's manual and are not sure where your automatic dip stick is, or are unable to read the fluid level, call Quality Transmission and we will give you the best advice possible.

A fluid level reading extremely above the "full" mark means your fluid may be too high. This may cause a churning action, turning the fluid into foam that can accelerate oxidation and introduce air into the oil circulate. Ultimately, transmission pressure may be affected causing transmission damage and affecting road safety.

A fluid level reading below the "add" mark means your fluid is too low, and this can cause transmission pressures to drop and not allow your transmission fluid to reach all the moving gear train components. This situation frequently indicates a leak somewhere in the transmission and may result in transmission damage.

Look at the fluid on the dip stick to determine its condition. Normal is a clear, red or a light brown color. Cloudiness may indicate your transmission fluid is getting "tired" and needs to be changed. If the fluid is contaminated with suspended metal or friction particles, it indicates wear and tear on the components of your transmission. Burnt fluid indicates damage from overheating or slipping. Fluid contaminated with water indicates a transmission oil or radiator cooler problem.
