Repair Procedures: Installation

  1. Install in the reverse order of removal.
    NOTE:
    • Matters that require attention when installing the transmission to engine 
      1. Check that there is no gap (A) between the torque converter housing and the engine block.

      2. If a gap is visible, it means that the oil pump gear key is not assembled properly to the torque converter hub. In this case, remove the intelligent variable transmission assembly and then reinstall the torque converter to intelligent variable transmission assembly according to the key shape of oil pump gear.

      3. Incorrect mounting of the oil pump gear key can lead to damage or can break if mounting bolts are tightened by force. In this case, replace the intelligent variable transmission assembly.
    NOTE: Follow the procedure as shown below based on reinstallation or replacement with a new intelligent variable transmission.
    • When reinstalling 
      1. If the differential oil seal is damaged and oil is leaking, replace the oil seal with a new one. When installing a new oil seal, use the SSTs (09452-26100, 09231-H1100).
      2. Check that the shift lever and manual control lever are placed in the "N" position.
      3. Check the IVTF level after refilling the intelligent variable transmission with fluid.
      4. Clear the diagnostic trouble codes (DTC) using the KDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear DTCs using the KDS at all times.
    • When replacing with a new intelligent variable transmission 
      1. Check that the shift lever and manual control lever are placed in the "N" position.
      2. Intelligent variable transmission is already filled with the specified amount of IVTF.

        For this reason, it is not necessary to refill and check the IVTF. However, the remaining IVTF in the IVTF cooler has to be drained.

      3. Install the transmission after draining the remaining IVTF by blowing air into the IVTF cooler hose.
      4. Clear the diagnostic trouble codes (DTC) using the KDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear DTCs using the KDS at all times.
      5. Reset the intelligent variable transmission adaptive values using the KDS.
