Your Jeep's automatic transmission is responsible for internally shifting the gears in your engine as you accelerate and decelerate. Like your engine, your transmission needs servicing from time to time. Your engine uses motor oil to keep its moving parts lubricated and moving. However, your transmission uses a substance called transmission fluid to keep the gears lubricated. It is recommended that you flush the transmission fluid in your Jeep once every 20,000 miles.
Place your Jeep in park on a flat, level surface and engage the parking brake.
Slide the floor jack under the rear end of your Jeep and then jack it up.
Place the drip pan under the rear bottom of the transmission. Place the socket on the transmission drain plug and turn it to the left to remove it. Allow all of the old transmission fluid to drain from your Jeep's transmission. Set the plug aside in a safe place and dispose of the old fluid properly.
Clean out the drain pan after disposing of the old fluid. Once it is clean and dry, set it back under the transmission drain plug.
Open the hood and remove the transmission fluid dipstick. It is located on the rear driver's side of the engine compartment. Place a funnel into the dipstick hole and add three quarts of transmission fluid. Allow the fluid to flush and then drain out into the drip pan.
Turn off the engine and then replace the transmission fluid drain plug.
Add the three quarts of fluid that have now drained into the pan back into your transmission via the funnel in the dipstick hole. Add a fourth quart of transmission fluid. Start the engine and check the level with the dipstick. If it needs additional fluid, add part of the fifth quart and then replace the dipstick.
Lower your Jeep down off of the jack stands.
