To check the fluid in your automatic transmission, the vehicle must be on a level surface with the engine and the transmission at normal operating temperature. While the engine is running, the emergency brake should be engaged and the shift selector in "park" when you read the dipstick. Note that some manufactures require the fluid to be checked while the car is in "neutral". Check with your vehicles owners manual to be sure. Consult your owners manual on where to find and how to read the dipstick.

If you have lost your owners manual and are not sure where your automatic dip stick is, or are unable to read the fluid level, call Dr. Trans 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 could cause transmission pressures to drop and not allowing 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 clear, or red in color. Cloudiness may indicate your transmission fluid is getting "tired" and needs to be changed. Contaminated with suspended metal or friction particles, indicate 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.

If the transmission fluid in your car is not at the proper level or condition, visit Dr Trans. In either case, have your transmission checked out as soon as possible. It is important and may minimize the damage to your transmission.
