The transmission fluid in your car lubricates and cools the transmission. Without the right amount of fluid, the transmission can fail, lock up or, even worse, require a complete replacement. To keep the transmission in working order between tuneups, check and add transmission fluid regularly. According to DRW Transmissions, you should check the transmission fluid every 3,000 miles. Symptoms of low transmission fluid include improper shifting or white smoke coming from under the hood.
Park your vehicle on a level surface.
Locate the dipstick for the transmission fluid, typically behind the vehicle's engine. Some manufacturers require that their vehicles remain running while checking the transmission fluid. This information is listed in the owner's manual for your vehicle.
Remove the dipstick and wipe it clean with a shop rag. Reinsert the dipstick into the transmission reservoir then remove it. Transmission fluid will cover the dipstick. Note the level of fluid for hot, warm or cold on the dipstick, depending on the temperature of the engine. DRW Transmission suggests checking the transmission fluid while the engine is warm; however, some vehicles must be checked when the engine is cold. Consult your owner's manual regarding the proper temperature for checking transmission fluid.
Place a funnel into the transmission reservoir.
Add transmission fluid slowly into the funnel, a little at a time. After each pour , measure the transmission fluid. Continue to do this until the transmission fluid hits the "Full" mark on the dipstick.
