    4. After mounting the DCT to the engine by pushing the DCT, tighten the mounting bolts making sure that there is no gap (less than 2 mm) between the clutch housing and the engine block.

      (If the bolt is tightened while there is a gap, then the spline of external damper or clutch will be damaged or broken.)

  2. Observe each separate procedure below for reinstallation or replacement with a new dual clutch 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 special tool.
      Item SST
      Installer Handle
      Differential oil seal 09453-3L240 09231-H1100
      Transfer driven gear oil seal (4WD only) 09473-D3500 09231-H1100
    2. After installing the DCT, check the oil level after refilling the DCT with oil.
    3. Clear the diagnostic trouble codes (DTC) using the KDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear the DTCs using the KDS at all times.

    When replacing with a new dual clutch transmission 

    1. After replacing the new DCT, it need not oil refill & level check procedure because oil is already filled with specified quantity inside new DCT.
    2. Clear the diagnostic trouble codes (DTC) using the KDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear the DTCs using the KDS at all times.
    3. Perform the DCT learning procedure by using the KDS.
      NOTE:
      • Before performing the DCT learning procedure using KDS, perform the learning process after leaving for 5 minutes in the idle state. Because it may be a problem to operation of wear compensation device when entering the DCT learning function at battery low voltage condition.
      • When performing the DCT learning function, Perform the DCT learning function twice for ensure accuracy and reliability of the clutch touch point.
