Fluid - Transfer Case: Service and Repair

Transfer Case Draining and Filling

1. Position a suitable container under the transfer case.





2. Remove the drain plug and drain the transfer case.





3. CAUTION: If the correct fill procedures are not followed, a transfer case failure can result.

NOTE: Fluid level must be just below the fill plug.

Remove the fill plug from the rear of the transfer case and check the fluid level.
If the fluid is below the level, fill with Motorcraft MERCON (R) Multi-Purpose Automatic Transmission Fluid XT-2-QDX or MERCON (R) equivalent.





4. CAUTION: Do not use air tools.

Tighten the drain and fill plugs.
