How to change the transmission fluid and filter in a Jeep Cherokee automatic AW4
The Jeep service manual recommends changing the fluid every 25,000 miles. I rarely see XJs get serviced that often.
Changing the fluid and filter requires removing the transmission pan. A handy drain plug on the AW4 allows for fluid draining. Odly for the XJ, it uses a 14 mm wrench to remove it. But, I recommend changing the filter as well.
