  1. Install in the reverse order of removal.
    CAUTION:
    1. Before reassembling the automatic transaxle to the engine assembly, make sure that there is no gap (A) between automatic transaxle and engine assembly as shown in the illustration below. Do not reassemble the automatic transaxle to the engine assembly when this gap (A) exists.

    2. While there is a gap, it would be meaning that the key of oil pump gear is not assembled properly to the torque converter hub. In this case, remove the automatic transaxle assembly and then reinstall the torque converter to automatic transaxle assembly according to the key shape of oil pump gear.

    3. If the mounting bolt is tightened forcibly in spite of a gap, key of oil pump gear will be damaged or broken. In this case, replace the automatic transaxle assembly.
    NOTE:
    • Follow each procedure below according to reinstallation or replacement with a new automatic transaxle.
  2. Reinstallation procedure:
    1. Replace the oil seal with a new one when ATF leak occurred because of differential oil seal damage.
      NOTE:

    2. Set the cup in front of the ATF cooler hose (B).
    3. Remove the remaining ATF by blowing air into ATF cooler hose.
    4. Install the ATF cooler hose (A) and (B).
