  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.
  6. Reinstall the magnet (2) onto the filter attachment tube (1) which is in the converter housing. See Fig 1 .
  7. Lubricate the gasket (3) on the control main filter with transmission fluid.
  8. Install, by hand, the control main filter (4) until the gasket on the control main filter touches the converter housing.
    NOTE: Turning the control main filter more than one full turn after gasket contact will damage the filter and may cause fluid leakage.
  9. Turn the filter ONE FULL TURN ONLY after gasket contact.
  10. Reinstall the drain plug (6) and drain plug seal (5). Tighten the drain plug to specification. See TORQUE SPECIFICATIONS  .

    NOTE: DTC P0701 may often set following fluid service. Cycling the ignition clears the code and allows Drive or Reverse range to be attained.

  13. Check the transmission fluid level. See CHECKING FLUID LEVEL & CONDITION  .
