Repair Procedures: Installation

CAUTION:
  • Note the value (A) carefully and check the value again before assembly.
  • Inputting an invalid value may cause the abnormal shifting shock while TCM learning.

  1. To install, reverse the removal procedure.
  2. Check fluid level after filling the automatic transaxle with fluid.

    (Refer to Hydraulic System - "FLUID ")

  3. Clear the diagnostic trouble codes (DTC) using the GDS.

    Information 

    • Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the GDS.
  4. Reset the automatic transaxle adaptive values using the GDS.

  5. Input the oil pressure characteristics using the GDS.
    1. Select 'Oil-pressure Characteristics (Solenoid Valve Replacement)' in the S/W Management.

    3. Check the code marked on the solenoid valve.
      CAUTION: (* Check the code at first before replacement)

  6. In order to prevent start delay and gear shift shock during acceleration and start, perform TCM learning after replacing the solenoid valve.
    NOTE: TCM Learning
    1. Learning Overview and Purpose
      • It aims to correct the deviation between transaxle products to reduce learning time and secure initial driving safety.
      • When gear shift shock has occurred at the 1-2-3-4-5-6 positions, delete the previous learning values using GDS device and perform TCM learning again.
    2. Conditions that Require Learning
      • After replacing automatic transaxle
      • After replacing TCM
      • After performing TCM reprogramming
    3. TCM Learning Method
      1. Condition
        • ATF temperature: 40-100°C
      2. Learning Method
        1. Learning with the vehicle stopped
          • While pressing and holding the brake (vehicle is stationery), set the throttle opening to 0% and repeat the following procedure four times.

        2. Learning with the vehicle running
          • Maintain a consistent throttle opening at the D position and gradually shift from 1st gear position to 6th gear position one by one. Then, gradually shift from 6th gear position to 1st gear position one by one (brake: on, throttle opening: 0%).
          • Throttle opening (for shifting to upper gear): 10 - 50% (less than 5% of throttle opening (APS) change)
          • Repeat the above procedure four times.
