Repair procedures
Inspection
Hyundai Palisade. Repair procedures   
Refer to the DTC manual for the check procedure.
Removal
Hyundai Palisade. Repair procedures   
Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
When the solenoid valve Diagnostic Trouble Codes (DTC) is on, perform the following procedure to replace it.
Automatic transaxle is composed of delicate components. Be careful not to cause any damage on the component in the course of assembly and disassembly.
Maintain clean condition so that foreign substance does not get into the automatic transaxle.
Use a coated apron, latex gloves, and stainless tray to prevent foreign substance from getting into the transaxle.
Automatic transaxle fluid (ATF) can be reused. Collect it using a clean 10-liter beaker.
1.
Turn ignition switch OFF and disconnect the negative (-) battery cable.
2.
Remove the battery and battery tray.
(Refer to Engine Electrical System - "Battery")
3.
Remove the air duct and air cleaner assembly.
(Refer to Engine Mechanical System - "Air Cleaner")
4.
Remove the under cover.
(Refer to Engine Mechanical System - "Engine Room Under Cover")
5.
Drain the coolant.(If equipped ATF warmer)
(Refer to Cooling System - "Coolant")
6.
Loosen the drain plug (A) and reinstall the drain plug after draining ATF totally.
Tightening torque :
33.3 - 43.1 N.m (3.4 - 4.4 kgf.m, 24.6 - 31.8 lb-ft)

9.
Remove the ATF cooling hose (A).

Hyundai Palisade. Repair procedures

Hyundai Palisade. Repair procedures   
Carefully install the clamp not to damage the hose.
Install the clamp in a correct direction not to be interfered with other parts.
After the installation, start the engine and then check if there are any leakages from the hose.
10.
Loosen the upper bolts (A) of the valve body cover.
Tightening torque :
11.8 - 13.7 N.m (1.2 - 1.4 kgf.m, 8.7 - 10.1 lb-ft)

11.
Loosen the bolts and then removing the valve body cover (A).
Tightening torque :
11.8 - 13.7 N.m (1.2 - 1.4 kgf.m, 8.7 - 10.1 lb-ft)
Hyundai Palisade. Repair procedures   
Be careful when removing the valve body cover because the remaining ATF remains in the valve body cover.

Installation
1.
To install, reverse the removal procedure.
2.
Inject the automatic transaxle oil and inspect the oil level.
(Refer to Automatic Transaxle System - "Automatic Transaxle Fluid")
3.
Clear the diagnostic trouble codes (DTC) using the diagnostic tool.
Hyundai Palisade. Repair procedures   
Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the diagnostic tool.
4.
In order to prevent start delay and gear shift shock during acceleration and start, perform TCM learning after replacing the solenoid valve.
(Automatic Transaxle Control System - "Repair Procedures")
Hyundai Palisade. Repair procedures   
After ATF level check or exchange, be sure to remove residual ATF on transaxle case.
(Be especially sure to remove residual ATF between automatic transaxle case and valve body cover)
