  5. Notice: Do NOT overfill the transaxle. The overfilling of the transaxle causes foaming, loss of fluid, shift complaints, and possible damage to the transaxle.

  6. Fill the transaxle to the proper level. Refer to Fluid Capacity Specifications.
  7. Inspect the transaxle fluid level. Refer to Transmission Fluid Check.
  8. Inspect for fluid leaks.
  9. 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.

  10. Reset the TAP values. Refer to Adapt Function.
