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 (B) and the engine block (C).

    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 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. 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 intelligent variable transmission assembly.

    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.
      3. The remaining IVTF in the IVTF cooler has to be drained and flushed to remove contaminants such as metal particles or clutch friction material. Improper flushing, or the lack of flushing, may result in severe damage to the replacement transmission
      4. After removing the A/T from the vehicle, insert the nozzle of the Kia Transmission Cooler Flush into the A/T cooler outlet hose and secure with the metal spring clamp.
      5. Hold transmission cooler flush can upright, remove protective flip-up cap and press button to release the flushing fluid and continue to hold the button until clear liquid comes out of the cooler inlet hose.
      6. Reverse the hoses and flush the cooler in the other direction until clear liquid comes out of the cooler outlet hose. Use the entire contents of the can to ensure thorough A/T cooler flushing.

        Clear liquid must flow freely in both directions through the A/T cooler. If not, the A/T cooler is restricted and the radiator or A/T cooler assembly must be replaced.

      7. After disconnecting the transmission cooler flush can, blow shop air (approximately 90 psi) through the cooler (in both directions) to dry it out.
      8. 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.
      9. Reset the intelligent variable transmission adaptive values using the KDS.

      10. Perform the oil pressure characteristics input procedure using the KDS.

      11. Perform the TCM adaptive values learning procedure.

    • When replacing with a remanufactured intelligent variable transmission
      1. Remanufactured intelligent variable transmission is not filled with specified quantity of IVTF. For that reason, it is necessary to refill and check the IVTF.
      2. Check the IVTF level after refilling the intelligent variable transmission with fluid.
      3. The remaining IVTF in the IVTF cooler has to be drained and flushed to remove contaminants such as metal particles or clutch friction material.

        Improper flushing, or the lack of flushing, may result in severe damage to the replacement transmission

      4. Use the "Kia Transmission Cooler Flush" to flush the cooler (Refer to Kia Chemical)
      5. After removing the A/T from the vehicle, insert the nozzle of the Kia Transmission Cooler Flush into the A/T cooler outlet hose and secure with the metal spring clamp.
      6. Hold transmission cooler flush can upright, remove protective flip-up cap and press button to release the flushing fluid and continue to hold the button until clear liquid comes out of the cooler inlet hose.
      7. Reverse the hoses and flush the cooler in the other direction until clear liquid comes out of the cooler outlet hose. Use the entire contents of the can to ensure thorough A/T cooler flushing.

        Clear liquid must flow freely in both directions through the A/T cooler. If not, the A/T cooler is restricted and the radiator or A/T cooler assembly must be replaced.

      8. After disconnecting the transmission cooler flush can, blow shop air (approximately 90 psi) through the cooler (in both directions) to dry it out.
      9. 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.
      10. Reset the intelligent variable transmission adaptive values using the KDS.
