Installation

To install, reverse the removal procedure.

1)	Before reassembling the automatic transaxle to the engine assembly, make sure that there is no gap (A) between automatic transaxle and engine assembly as below illustration. Do not reassemble the automatic transaxle to the engine assembly when this gap (A) exist.

While there is a gap, It would be meaning that the key of oil pump gear is not assembled properly to the torque converter hub. In this case, remove the automatic transaxle assembly and then reinstall the torque converter to automatic transaxle assembly according to the key shape of oil pump gear.

[Correct Assembly (A) - Oil Pump Key Part (B) Engaged Properly]

Hyundai Palisade. Repair procedures

[Incorrect Assembly (C) - Torque Converter Protruded due to Interference with the Oil Pump Key Part (D)]

Hyundai Palisade. Repair procedures

If the mounting bolt is tightened forcibly in spite of a gap, key of oil pump gear will be damaged or broken. In this case, replace the automatic transaxle assembly.

•	Follow the separted each procedure as below according to reinstallation or replacing with a new automatic transaxle.

In case of the reinstallation.

(1)

Replace the oil seal with a new one when ATF leak occurred because of differential oil seal damage.

•	When installing the new oil seal, use the special service tool.

(2)	Check the ATF level after refilling the automatic transaxle with fluid. (Refer to Automatic Transaxle System - "Automatic Transaxle Fluid")

(3)

Clear the diagnostic trouble codes (DTC) using the diagnostic tool.

•	Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the diagnostic tool.

In case of the replacing with a new automatic transaxle.

•	New automatic transaxle is already filled with specified quantity ATF. For that reason, it does not necessary to refill and check the ATF but the remaining ATF inside of ATF cooler have to be removed.

(1)	Set the air blow gun in front of the ATF cooler hose (A).

(2)	Set the cup in front of the ATF cooler hose (B).

(3)	Remove the remaining ATF by blowing air into ATF cooler hose.

(4)	Install the ATF cooler hose (A) and (B).

(5)

Clear the diagnostic trouble codes (DTC) using the diagnostic tool.

•	Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the diagnostic tool.

(6)	Reset the automatic transaxle adaptive values using the diagnostic tool.

(7)

Perform the oil pressure characteristics input procedure.

•	Oil pressure characteristics (bar code) location

•	Oil-pressure characteristics input (Transaxle exchange)

(8)	Perform the TCM adaptive values learning procedure. (Refer to Automatic Transaxle Control System - "Repair Procedures")
