    NOTE: Refer to FASTENER NOTICE
  11. Hand start the bolts.

    Tighten:  Tighten the bolts to 14 N.m (124 lb in).

  12. Install the transmission side cover. Refer to Case Side Cover Replacement .
  13. 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.
  14. Reset the TAP values. Refer to Transmission Adaptive Functions .
