Transfer cases
(4WD Grand Cherokees only)
Grand Cherokee WJ’s use three different 4-wheel drive transfer cases, identified on the interior shift console. A circular ID tag is attached to the rear of each transfer case. The ID tag provides the transfer case model number, assembly number, gear ratio and location of manufacture. The transfer case serial number also represents the date of build.

Transmissions (automatic)
See also: WJ Transmission service & maintenance procedures
FLUID CAUTION:
- ATF+4® MUST always be used in vehicles that were originally filled with ATF+4®.
- ATF+4® is compatible with ATF+3 and can be used to top off vehicles that currently have ATF+2 or ATF+3.
- DO NOT use ATF+2 or ATF+3 to top off vehicles that have ATF+4® fluid
FLUID ADDITIVES:
DaimlerChrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic transmission fluids listed above. Exceptions to this policy are the use of special dyes to aid in detecting fluid leaks. Various “special” additives and supplements exist that claim to improve shift feel and/or quality. These additives and others also claim to improve converter clutch operation and inhibit overheating, oxidation, varnish, and sludge. These claims have not been supported to the satisfaction of DaimlerChrysler and these additives must not be used. The use of transmission “sealers” should also be avoided, since they may adversely affect the integrity of transmission seals.
FILTER SEAL CAUTION (545RFE):
The primary oil filter seal MUST be fully installed flush against the oil pump body. DO NOT install the seal onto the filter neck and attempt to install the filter and seal as an assembly. Damage to the transmission will result. Install the new primary oil filter seal in the oil pump inlet bore. Seat the seal in the bore with the butt end of a hammer, or other suitable tool. Place replacement filter in position on valve body and into the oil pump. Install screw to hold filter to valve body. Tighten screw to 40 in. lbs. torque.

Mopar Antifreeze/CoolantThe recommended mixture is 50/50 ethylene-glycol and water. Never use pure antifreeze.
Only Mopar Antifreeze Coolant, 5 Year/100,000 Mile Formula (glycol base coolant with corrosion inhibitors called HOAT) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water. Note: Antifreeze mixture must always be at least 44%, all climates year round. Maximum protection (-90d) is provided with a 68% mixture protection.
