  6. Reposition and connect the electrical connectors to the following:
    7. • Automatic transaxle fluid pressure manual valve position switch assembly (395)
    • 2-3 Shift solenoid valve assembly (315B)
    • If equipped internal mode switch
  7. Install the case side cover. Refer to Control Valve Body Cover Replacement .

    8. 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 Adapt Function.
