Hyundai Santa Fe DM 2013-2018 Service Manual / Automatic Transaxle System / Automatic Transaxle Control System / Torque Converter Control Solenoid Valve (T/CON_VFS). Repair procedures

Inspection

1.	Turn ignition switch OFF.

2.	Remove the air duct.

3.	Disconnect the solenoid valve connector(A).

4.	Measure resistance between sensor signal terminal and sensor ground terminal.

5.	Check that the resistance is within the specification.

Removal

1.	Remove the air duct.

2.	Remove the battery and the battery tray.

Remove the under cover(A).

Tightening torque :

7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)

4.	Drain the coolant.

Remove the drain plug (A) and reinstall the drain plug after draining ATF totally.

Drain plug tightening torque:

38.2 ~ 48.1 N.m (3.9 ~ 4.9 kgf.m, 28.2 ~ 35.4 lb-ft)

Replace the gasket before reinstalling the drain plug.

6.	Remove the wiring bracket installation bolt (A).

Remove the ATF Injection hole(eyebolt)(A).

Eyebolt tightening torque:

2.9 ~ 4.9 N.m (0.3 ~ 0.5 kgf.m, 2.2 ~ 3.6 lb-ft)

Replace the O-Ring (A) before reinstalling the eyebolt.

8.	Disconnect the coolant hose (B) after removing the coolant hose clamp (A).

Disconnect the hose (B) after removing the automatic transaxle fluid cooler hose clamp (A).

When hose&pipe assembly

Align marking of pipe(B), marking of hose(A), and matching color each other.

10.

Remove the valve body cover (A).

Tightening torque:

(A) 13.7~ 15.7N.m (1.4 ~ 1.6 kgf.m, 10.1 ~ 11.6lb-ft)

•	Replace the gasket (A) before reinstalling the valve body cover.

11.

Remove the bolts (C) after disconnecting the solenoid valve connector (B) and the oil temperature sensor connector (A).

Tightening torque:

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

12.

Remove the solenoid valve support bracket (B) and the valve body mounting bolt (A-1ea).

Tightening torque :

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

13.	Remove the torque converter control solenoid valve (A).

Installation

Install in the reverse order of removal.

•	Adding coolant.

•	Adding Automatic Transaxle Fluid(ATF).

•	Perform Transaxle Control Module(TCM) learning after replacing the valve body to prevent slow transaxle response, jerky acceleration and jerky startup.
