Use only Mopar® ATF+4 or Automatic Transmission Fluid in the transmission sump and take this chance to remove and change the filter, removing the magnet inside the oil sump with a clean, dry piece of cloth when you finish. Anytime the transmission is taken apart, the fluid and filter should be replaced. First, support your vehicle on a hoist and remember to put a large-opening container under the transmission pan. One of the bolts in the
Oil Pan comes from the factory with a sealing patch attached. You should remove this patch for reuse. Unscrew the pan bolts and hit the pan at one edge so it moves, letting the oil drain first. Fasten a new filter together with another new O-ring at the bottom of the valve body using retaining screws set at 5 Nm (45 in. lbs.). Usually, before installing the oil pan bolt into the hole, you should apply Lock & Seal Adhesive on the sealing patch of the bolt. Rinse out the oil pan and magnet and after that, install the pan again with Mopar® Silicone Adhesive, tightening the bolts to a torque of 20 Nm (14.5 ft. lbs.). Introduce four quarts of Mopar® ATF+4, Automatic Transmission Fluid, into the dipstick open, turn on the engine and let the vehicle idle for about one minute. After you've used the parking and service brakes, move the selector lever to every position, finishing in park or neutral. See that the transmission fluid is between 1 and 8 millimeters or 1/8 to 1/3 inch, below the lowest mark on the dipstick. Check the level of the transfer case fluid while the vehicle is at its operating temperature, about 140° F (60° C) and push the dipstick into the dipstick opening tightly so no dirt gets inside the transmission.
