| Automatic transmission fluid serves multiple functions. It provides lubrication, keeps seals soft, protects internal parts and acts as a coolant for your transmission.
- Automatic transmissions in recent model vehicles should be checked while the engine is running.
- Make sure the vehicle is on a level surface with the emergency brake applied, and the transmission in park or neutral. (Check your owner's manual for information on whether your vehicle should be in park or neutral when checking the transmission fluid and where your transmission's dipstick is located.)
- Raise the hood and locate your transmission's dipstick, making sure to avoid any hot or moving parts of the engine.
- Once you've located the dipstick, remove it, wipe off the fluid, and re-insert it. Remove the dipstick again to check the fluid level. The level should be within the "Full" range.
- Clean automatic transmission fluid should have a pink tint.
- Amber to brown fluid is a sign that the fluid may need to be changed.
- Brown or black, burnt-smelling fluid is a sign of internal failure or lack of proper maintenance. If your fluid shows these signs, consult a AAA Approved Auto Repair facility for the proper diagnosis.
On most models, finding an accessible way to check the manual transmission and differential fluid level is very difficult. It is recommended that service and inspection of these fluids be performed by a qualified technician. Refer to your owner's manual for specific service information.
