TECHNICAL SERVICE BULLETIN

Reference Number(s): 10-AT-011, Date of Issue:  August, 2010
HYUNDAI: All
GROUP: Automatic Transaxle
Superceded Bulletin(s): 09-AT-002-1, Date of Issue:  December, 2009
NOTE: This bulletin supersedes TSB 09-AT-002-1 to include Equus and Sonata HEV.
CAUTION: After replacing a transaxle or reprogramming the PCM/TCM, to improve the shift quality condition, follow this procedure to reset and relearn the adaptive learning.

DESCRIPTION

The PCM or TCM contains logic to adjust solenoid duty and line pressure as needed to compensate for normal clutch wear over the life of the transaxle. This bulletin provides the procedures necessary to reset (erase) and "relearn" the PCM/TCM adaptive values.

After the following repairs have been completed, the PCM/TCM adaptive values must be reset in order to provide optimum shift quality:

I. RESET PCM/TCM ADAPTIVE VALUES WITH GDS: 

  1. Attach a GDS and select VIN and A/T  menu.
    G06948843
  2. From the main screen, select "Option Treatment" 
    G06948844
  3. Select "Resetting Auto T/A values"  and follow the screen prompts. Turn the ignition key off for 10 seconds.
    G06948845
    NOTE: GDS must be used to reset the adaptive learning for the following vehicles.

    II. RELEARN ADAPTIVE VALUES: 

    NOTE: After the adaptive values have been reset (erased), an "adaptive learning" procedure must be completed as shown below.
  4. Attach a GDS and select VIN and A/T. 
  5. Select Current Data and "Throttle Position".
    G06948846
  6. Drive the vehicle until the ATF temperature is within the range shown in the ATF TEMPERATURE RANGES  Table.
  7. Request an assistant to monitor the GDS. Accelerate from a stop at the specified TPS specification while the transmission shifts through gears 1-2-3-4-5-6 and decelerate slowly to a stop. Stop for 5 seconds. Repeat 5 times.
    NOTE: Hold the accelerator pedal steady during the upshifts.
    CAUTION: Do not exceed legal speed limits.

    If additional adaptation is needed, perform the following additional procedures: 

  8. Perform several sequential downshifts (5-4, 4-3, 3-2 and 2-1) at small to moderate throttle openings.
  9. Perform several skip shifts (6-4, 5-3, 5-2, 3-1, etc.) at moderate to large throttle openings.
  10. With the vehicle stopped, move the shift lever from P to N to D and back, stopping 3~5 seconds in each gear. Repeat 5 times.
NOTE: Adaptive learning occurs only within the ATF temperature ranges shown:
