MULTI-MODE MANUAL TRANSAXLE SYSTEM CALIBRATION


  1. SYNCHRONIZATION POSITION CALIBRATION

    For smoother shifting, the transmission control ECU learns the synchronization position of the transaxle gears. Perform the synchronization position calibration of the multi-mode manual transaxle while driving the vehicle after repairing system components.

    Tech Tips

    When replacing the following parts, proceed with the operation in the order listed in the table below.

    Part installed Operation order See procedure

    • Transaxle assembly

    • Transaxle parts (inside gear box)

    • Shift and select actuator (with clutch actuator)

    • Transmission control ECU

    Do not clear (initialize) parts other than those specified in the "Part Installed" column in the table above.


    1. While driving the vehicle in M-mode, shift up and down between 1st and 5th at the vehicle speeds specified below.

    2. Check that the gears shift smoothly.

      Recommended Gear Shifting Speeds
      Gear Change Gear Position Vehicle Speed
      Up shift 1st→2nd 25 to 48 km/h (15.5 to 29.8 mph)
      2nd→3rd 46 to 90 km/h (28.5 to 55.9 mph)
      3rd→4th 67 to 131 km/h (41.6 to 81.4 mph)
      4th→5th 85 to 167 km/h (52.8 to 103.8 mph)
      Down shift 2nd→1st 25 to 48 km/h (15.5 to 29.8 mph)

      Tech Tips


      • Leave an interval of more than 2 seconds between gear changes.

      • If there is a shock when changing gears after the synchronization position calibration, perform the synchronization position calibration again.
