Repair Procedures: Installation

  1. To install, reverse the removal procedures.
    NOTE: Matters that require attention when installing the transmission to engine
    1. Check that there is no gap (A) between the torque converter housing (B) and the engine block (C).

    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 (IVT) and then reinstall the torque converter to IVT 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 IVT.
    NOTE:
    • Follow the procedure as shown below based on reinstallation or replacement with a new intelligent variable transmission.
  2. In case of the reinstallation.
    1. If the differential oil seal is damaged and fluid 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 the Intelligent Variable Transmission Fluid (IVTF) level after refilling the intelligent variable transmission with fluid.

      (Refer to Intelligent Variable Transmission (IVT) System - "FLUID ")

    3. Injection the coolant.

      (Refer to Engine Mechanical System - "COOLANT ")

    4. Clear the diagnostic trouble codes (DTC) using the diagnostic tool. Disconnecting the battery negative terminal will not clear the DTCs.

      Clear DTCs using the diagnostic tool at all times.

    NOTE:
    • Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the diagnostic tool.
  3. In case of the replacing with a new IVT.
  1. 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.

  2. Injection the coolant.

    (Refer to Engine Mechanical System - "COOLANT ")

  3. Clear the diagnostic trouble codes (DTC) using the diagnostic tool. Disconnecting the battery negative terminal will not clear the DTCs. Clear DTCs using the diagnostic tool at all times.
    NOTE:
    • Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the diagnostic tool.
  4. Reset the intelligent variable transmission adaptive values using the diagnostic tool.
