FLUID RECOMMENDATION



Pickups and MPV

Use API GL-5, SAE 75W-80 gear oil for year-round use when refilling or adding fluid to the transfer case.

Navajo

Use Dexron®II automatic transmission fluid when refilling or adding fluid to the transfer case.

LEVEL CHECK



Position the vehicle on level ground. Remove the transfer case fill plug (the upper plug) located on the rear of the transfer case. The fluid level should be up to the fill hole. If lubricant doesn't run out when the plug is removed, add lubricant until it does run out and then replace the fill plug.

DRAIN AND REFILL



The transfer case is serviced at the same time and in the same manner as the transmission. Clean the area around the filler and drain plugs and remove the filler plug on the side of the transfer case. Remove the drain plug on the bottom of the transfer case and allow the lubricant to drain completely. Clean and install the drain plug. Add the proper lubricant.
