Mechatronic Assembly: Installation

    CAUTION: Lubricate all of the O-ring seals with clean continuously variable transmission (CVT) automatic transmission fluid. Be careful not to nick, cut or damage the O-ring seals when installing the feed tubes into the transaxle case half or internal damage to the transaxle will occur.

  1. Lubricate the new O-ring seals with clean CVT automatic transmission fluid and install the O-ring seals on the feed tubes.
    1. Install new O-ring seals on the inside and outside clutch (manual valve) supply feed tube.
    2. Install new O-ring seals on the primary pressure feed tube.
    3. Install new O-ring seals on the secondary pressure feed tube.
    4. Install new O-ring seals on the main (pump) pressure feed tube (smaller tube).
    2. CAUTION: Lubricate all of the O-ring seals with clean CVT automatic transmission fluid. Be careful not to nick, cut or damage the O-ring seals when installing the mechatronic assembly or internal damage to the transaxle will occur.
    NOTE: Note the location of the 5 feed tubes.

  2. Lubricate the O-ring seals with clean CVT automatic transmission fluid and install all of the feed tubes into the case.
    1. Align the inner tube and install the clutch (manual valve) supply feed tube.
    2. Install the primary pressure feed tube.
    3. Install the secondary pressure feed tube.
    4. Install the main (pump) pressure feed tube (smaller tube).
    5. Install a new torque converter clutch pressure feed tube.
    3. CAUTION: Do not touch the electrical connector pins. Electrostatic charge may occur and will cause damage to the mechatronic unit.

  3. Position the mechatronic unit onto the case.
  4. Tighten the mechatronic bolts in sequence, in 2 stages.
    • Stage 1: Tighten to 5 N.m (44 lb-in).
    • Stage 2: Tighten an additional 40 degrees (1/8 turn).

    8. CAUTION:
    1. Make sure that the fluid filter pickup tube seal was removed from the bore when the filter was removed. Failure to remove the seal prior to installing the new filter will result in transaxle failure.
    2. Make sure that the transmission fluid filter is fully seated into the bore. If the filter is not correctly installed, internal transaxle damage will occur.

  13. Connect the transaxle bulkhead electrical connector.
  14. Fill the transaxle with approximately 4.7 L (5 quarts) of clean CVT automatic transmission fluid. Use the transmission fluid level setting procedure to fill the transaxle. For additional information, refer to TRANSMISSION FLUID LEVEL CHECK AND SETTING .
  15. If a new transaxle or a mechatronic main control valve body assembly is installed, the TCM will need to be reflashed to the latest level calibration available. If the TCM is not reflashed, the wrench light on the dash may illuminate and internal transaxle damage may occur.
