This bulletin applies to Hyundai automatic transaxles in the vehicles listed here. After replacing a transaxle or reprogramming the PCM/TCM, to improve shift quality, a procedure must be followed to reset and relearn the adaptive learning.
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 replacing an automatic transaxle or reprogramming or exchanging a PCM/TCM from another vehicle, the PCM/TCM adaptive values must be reset in order to provide optimum shift quality.
