    NOTE
    The PCM maintains 3 types of transaxle adapt parameters which are used to modify transaxle line pressure. The line pressure is modified to maintain shift quality regardless of wear or tolerance variations within the transaxle. Whenever the transaxle is replaced, the transaxle adapts must be reset as follows:

    1. Step 1: Turn the ignition key ON . Enter the self-diagnostic system.
    2.  
    3. Step 2: Select PCM override PS13 (TPS SENSOR LEARN).
    4.  
    5. Step 3: Press the WARMER button. The Driver Information Center (DIC) should display 09, indicating that the Garage Shift Adapt value has been reset.
    6.  
    7. Step 4: Select PCM override PS14 (TRAN ADAPT).

    11. Step 6: Press the WARMER button. The DIC should display 09, indicating the Steady State Adapt (SSA) value has been reset.
      NOTE
      The PCM maintains a value for transaxle oil life. This value indicates the percentage of oil life remaining and is calculated based on transaxle temperature and speed. When the vehicle is new, the transaxle oil life value is 100. As the vehicle operates, the percentage will decrease. Whenever the transaxle is replaced, the transaxle oil life indicator should be reset to 100 as follows:

    12.  
    13. Step 1: Turn the ignition key ON , but leave the engine OFF.
    14.  
    15. Step 2: Press and hold the OFF and REAR DEFOG buttons on the DIC until the message TRANSAXLE OIL LIFE RESET is displayed on the DIC.
