How to Tell If the Auto Transmission Is Going

An automatic transmission is generally considered to be more durable than a manual transmission. However, automatic transmissions are not immune from ordinary wear and tear or improper maintenance. Replacement can be expensive, but prevention through regular maintenance can significantly prolong the life of the transmission. It is always prudent to keep a watchful eye on your automatic transmission. Diagnosing minor problems today will allow time to prepare for an expensive future replacement or repair.

Instructions

1. Keep alert to changes in the transmission's operation, such as a gradual change in shift points or unusual noises.

2. Check the transmission fluid for normal color by withdrawing the transmission's dipstick and looking at the fluid at the bottom of the dipstick. The transmission dipstick is usually located on the passenger's side of the vehicle. Transmission fluid which is clear and red indicates that the transmission is operating normally.

3. Check the transmission fluid on the dipstick for an extremely dark or brownish color accompanied by a burned smell. These colors indicate that a band or clutch within the transmission is failing, usually due to overheating.

4. Check the transmission fluid on the dipstick for any bubbles, which indicate that the transmission has either too much fluid in it or an internal air leak.

5. Check the transmission fluid on the dipstick for signs of solid residue which indicates that the transmission may have defective bands or bearings.
