TJ Fluid Type/Capacities
The following chart has the fluid/part type listed, the capacity/size needed, the brand & part number I recommend, and the factory (OEM) recommended replacement interval. Since I'm a maintenance freak, my schedule varies dramatically from the OEM recommendation.
These quantities are for my 2004 TJ, but should work for other similar systems. Check in your owners manual if you are unsure.
