Transmission Fluid Drain and Fill Procedure

Normal maintenance and lubrication requirements do not necessitate periodic automatic transmission fluid changes. If a major service, such as a clutch, band, bearing, etc., is required, it will have to be removed for service. At this time, the torque converter (7902), transmission oil cooler (7A095) and transmission oil cooler inlet tube (7A030) and oil cooler tube (7A031) must be thoroughly flushed to remove any dirt. When used under continuous or severe conditions, the transmission and torque converter should be drained and refilled with fluid as specified.

 CAUTION: Use of a fluid other than specified could result in transmission malfunction and/or failure.

Refer to the Vehicle Certification Label affixed to the LH front door lock face panel or door pillar for the transmission code.

When filling a dry transmission and torque converter, refer to Specifications for capacity. Check the fluid level.

Procedures for partial drain and refill, due to in-vehicle service operation, are as follows:

1. Raise vehicle on a hoist or jackstands. Refer to Section 00-02.

2. Place drain pan under transmission.

3. Loosen oil pan retaining bolts and drain fluid from transmission.

4. When fluid has drained to level of pan flange, remove rest of pan bolts working from the RH side, and allow it to drop and drain slowly.

5. When all fluid has drained from transmission, remove and thoroughly clean transmission oil pan (7A194) . Discard oil pan to case gasket (7A191).

6. Place a new oil pan to case gasket on transmission oil pan, and install transmission oil pan on transmission.

7. Lower vehicle.

8. Fill transmission to proper level with Motorcraft MERCON ® Multi-Purpose Automatic Transmission Fluid XT-2- QDX or equivalent Mercon® approved fluid.
