Acura Integra owners check transmission fluid by pulling out the transmission dipstick on a running car and checking its color and level. Transmission fluid that's pinkish and clear means the fluid and transmission is good.
The color and level of the transmission fluid may indicate problems. A red or reddish brown color on the driveway may mean a leak. Dark or black fluid may mean the fluid is old, and it's time to change the fluid. Finally, particles in the fluid may mean loose or worn seals in the transmission system. Checking the fluid system against the owner's manual is a good preventive practice. Adding a monthly maintenance check helps drivers stay on top of possible problems.
