Valve Body Assembly: Removal

NOTE: Manufacturer refers to valve body assembly as control valve assembly.
CAUTION: When replacing the control valve assembly it may be necessary to erase EEPROM in TCM. See appropriate DIAGNOSIS - RE5R05A article in AUTOMATIC TRANSMISSION.
  1. Disconnect negative battery terminal.
  2. Drain transmission fluid through drain plug.
  3. Disconnect heated oxygen sensor No. 2 harness connector.
  4. Remove oil pan and oil pan gasket.
  5. Remove magnets from oil pan.
  6. Check foreign materials in oil pan to help determine cause of malfunction. If transmission fluid id very dark, smells burned, or contains foreign materials, the frictional material (clutches, bands) may need replacement. A tacky film that will not wipe clan indicates varnish build up. Varnish can cause valves, servo, and clutches to stick and can inhibit pump pressure.
    NOTE: If frictional material detected, replace radiator after repair of transmission.
  7. Disconnect transmission assembly harness connector.
  8. Disconnect transmission fluid sensor No. 2 connector. Use care to not damage connector. See Fig 1.
