How do I Know if I Need Transmission Fluid?
How do I know if I need transmission fluid?
-- Miashia Brown, Birmingham, AL
The best place to find the answer to your question is your owner’s manual. The answer depends on your vehicle. Some new vehicles have factory-sealed systems and there is no way to check the transmission fluid. On most vehicles there is a dipstick similar to the dipstick you use to check your motor oil. Again, read the manual and follow the procedure it outlines. Some vehicles require checking the transmission fluid while the vehicle is running and hot so be very careful. Safety first! You may want to have a service station check it for you.
