Removal Procedure

    Important: DO NOT drain the fluid if only the control main filter is being replaced.


    Object Number: 658982  Size: SH
  1. Remove drain plug (6) and drain plug seal (5). Drain the transmission fluid into a suitable container.
  2. Important: Use a standard strap-type filter wrench to remove the control main filter.

  3. Remove the filter (4) by rotating it in the counterclockwise direction.
  4. Remove the magnet (2) from the filter attachment tube (1) in the converter housing or from the top of the control main filter (3).
  5. Clean any metal debris from the magnet. Presence of any metal pieces larger than dust may indicate that transmission replacement or overhaul is required.

Installation Procedure


    Object Number: 658983  Size: SH
  1. Reinstall the magnet (2) onto the filter attachment tube (1) which is in the converter housing.
  2. Lubricate the gasket (3) on the control main filter with transmission fluid.
  3. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  4. Install, by hand, the control main filter (4) until the gasket on the control main filter touches the converter housing.
  5. Notice: Turning the control-main filter more than ONE FULL TURN after gasket contact will damage the filter and may cause fluid leakage.

  6. Turn the filter ONE FULL TURN ONLY after gasket contact.
  7. Reinstall the drain plug (6) and drain plug seal (5).
  8. Tighten
    Tighten the drain plug to 35 N·m (26 lb ft).

  9. Refill Transmission with DEXRON®III Automatic Transmission Fluid. Refer to Fluid Capacity Specifications .
  10. Important: DTC P0701 may often set following fluid service. Cycling the ignition clears the code and allows Drive or Reverse range to be attained.

  11. Cycle the ignition until Drive or Reverse range is attained.
  12. Important: Fluid remains in the external circuits and transmission cavities after draining the transmission.

  13. Check the transmission fluid level.
