  17. NOTE: It is recommended that the 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.
  18. Reset the TAP values. Refer to Transmission Adaptive Functions .
  19. CAUTION: Check the transmission fluid level immediately after adding fluid and before vehicle operation. Do not overfill the transmission. An overfilled transmission may result in foaming or fluid to be expelled out the vent tube when the vehicle is operated. Overfilling will result in possible damage to the transmission.
  20. Check and fill the transaxle as necessary.
