    Object Number: 48209  Size: SH
  1. Remove the case side cover. Refer to Control Valve Body Cover Replacement .
  2. Use a flat-bladed tool to disconnect the electrical connectors from the solenoid valves (315A, 315B, 322, 334 and 440), the TFP manual valve position switch (395) and the temperature sensor (391).

    Important: Do NOT remove the bolt (205) that holds the oil pump together.

  4. Remove the oil pump bolts (206, 207).

  5. Object Number: 48212  Size: SH
  6. Remove the oil pump (200) from the valve body (300).

Installation Procedure


    Object Number: 48212  Size: SH
  1. Install the oil pump (200) to the valve body (300).

  2. Object Number: 164795  Size: MH

    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.

  3. Install the oil pump bolts (206, 207).
  4. Tighten

        • Tighten the M6 X 1.0 X 85 bolts (207) to 12 N·m (106 lb in).

  5. Connect the electrical connectors to the solenoid valves (315A, 315B, 322, 334 and 440), the TFP manual valve position switch (395) and the temperature sensor (391).
  6. Install the case side cover. Refer to Control Valve Body Cover Replacement .
  7. Important: It is recommended that transmission adaptive pressure (TAP) information be reset.

    Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

  8. Reset the TAP values. Refer to Transmission Adaptive Functions .
