Record the preset radio stations.
Refer to the 2019 Santa Fe Shop Manual, Automatic Transaxle System, Automatic
Transaxle and Repair Procedures and remove the transmission.

4.

Measure the depth of the torque converter in
the converter housing. If the measurement is
less than the specification, rotate the torque
converter in both directions and push inward
until the measurement is at specification.
Specification: 0.39~0.51 inch (10~13 mm).

NOTICE
Do not use an impact gun to force
the transmission installation.
5.

Reinstall the transmission.

6.

Reconnect the battery.
Input the radio stations recorded in Step 2.

7.

Remove the transaxle fill plug.
Use a funnel to add approximately 1 quart of
SP4-M ATF through the fill plug opening.
Reinstall the fill plug.
Attach the GDS and select Data Analysis, A/T
menu and Oil Temperature Sensor.
Start the engine and shift to Park. When the
ATF is at the low end of 122°F~140°F
(50~60°C), remove the level checking plug.
The level is correct when oil flows out of the
level checking plug in a thin steady stream.
Collect and dispose of any excess fluid in
accordance with local regulations.

8.

Drive the vehicle when the ATF temperature is cold and hot and confirm the transmission shifts
correctly.
The Service Procedure is now complete.
