Kia Sportage: Valve Body

Description and Operation

 Description

The valve body is essential to automatic transaxle control and consists of various valves used to control the oil feed from the oil pump. Specifically, these valves consist of pressure regulator valves, oil redirection valves, shift valves, and manual valves. The body also features electronic solenoid valves that ensure smooth gear changes.

Repair procedures

Removal

1. Remove the battery and the battery trау. (Refer to "Charging system" in EE group.)

2. Remove the under cover (A).

Tightening torque: 19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~ 18.1 lb-ft)

3. Replace new gasket and the plug after draining the automatic transaxle fluid by removing the drain plug. (Refer to "Hydraulic system (Fluid)" in this group)

4. Remove the valve body cover (A) and eyebolt (B).

Tightening torque:

(A) 13.8 ~ 14.7 N.m (1.3 ~ 1.5 kgf.m, 9.4 ~ 10.8 lb-ft)

(B) 34.3 ~ 44.1 N.m (3.5 ~ 4.5 kgf.m, 25.3 ~ 32.6 lb-ft)

CAUTION

Always replace the gasket of the eyebolt use new one whenever loosening eyebolt.

5. Remove the plate and the detent spring (A) after removing the bolt.

Tightening torque: 24.5 ~ 35.3 N.m (2.5 ~ 3.6 kgf.m, 18.1 ~ 26.0 lb-ft)

6. Remove the bolt (3ea) after disconnecting the solenoid valve (B) connector 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)

7. Remove the valve body assembly (A).

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

Installation

1. Installation is the reverse of removal.

CAUTION

After replacement or reinstallation procedure of the valve body assembly, must perform procedures below.

NOTE

• Continue to apply liquid gasket at application points at the valve body cover with Ø2.5mm (0.0984in.) thickness.

Liquid gasket Part name : Threebond 1281B or LOCTITE FMD-546

• Adding automatic transaxle fluid. (Refer to "Hydraulic system (Fluid)" in this group)
• Perform TCM learning after replacing the valve body to prevent slow transaxle response, jerky acceleration and jerky startup. (Refer to "Automatic transaxle control system (Repair procedures)" in this group)
