DESCRIPTION:

If you are servicing a transaxle for harsh or delayed engagement during the Park to Reverse or Park to Drive shift, compare the vehicle with another vehicle of the same year and model. If the engagement shock or delay is more noticeable than other vehicles, follow the repair procedure shown below:

REPAIR PROCEDURE:

1. Check the ATF level when the engine is idling in "N" according to TSB 01-40-013. Adjust the ATF level as needed.

2. Check that idle speed is within specification. If not, inspect the Idle Speed Actuator according to the appropriate shop manual, Fuel System Section.

3. Check the engine and transaxle mounting brackets and roll support brackets for broken or deteriorated mounts. If necessary, replace the mounts.

4. Attach the Hi-Scan Pro and check for Diagnostic Trouble Codes in both the "ENGINE" and "AUTOMATIC TRANSAXLE" menu. If DTCs are found, repair according to the appropriate TSB or shop manual.





5. Attach the Hi-Scan Pro and select "HYUNDAI VEHICLE DIAGNOSIS" menu, "AUTOMATIC TRANSAXLE" menu, "CURRENT DATA" menu and "FLUID TEMPERATURE SENSOR". Confirm the oil temperature sensor operates correctly as shown. If not, replace the oil temperature sensor.
