Valve Body
Valve Body
CAUTION!
Do not run engine with the oil pan removed or without ATF filling and do not tow vehicle.
• Valve body or wiring harnesses can also be removed with transmission installed.
• Insert seals with ATF. Other lubricating substances lead to functional problems in the hydraulic transmission control.
• Always replace a soiled or faulty valve body.
• Do not use fluffy cloths!
• After installing oil pan, ATF level must be checked and topped off => [ ATF Level, Checking ] Testing and Inspection.
Valve Body, Removing
Special tools, testers and auxiliary items required
• Torque Wrench (V.A.G 1331)
• Torque wrench (V.A.G 1756)
- Remove oil pan => [ Automatic Transmission Fluid Pan ] Service and Repair.
- Remove oil strainer => [ Oil Strainer ] Service and Repair.
- Disconnect connector form solenoid valves
To unlock connector housing on the solenoid valves, use a flat head screwdriver with a 2.5 mm shaft diameter.
CAUTION!
If a connector or the connector housing are damaged, then the wiring harness or solenoid valve must be replaced.
- Disconnect connectors
- Remove bracket for connectors
- Disconnect Transmission Fluid Temperature Sensor (G93) and carefully remove it from the valve body.
- Bend securing plate on shift lever back.
- Remove shift lever - 1 - from shift rod.
- Carefully hold shift lever - 1 - in place using pliers - 2 - so that torque is not transferred to Multi-Function Transmission Range (TR) Switch (F125).
- Make sure the valve - 3 - on the valve body in which the shift lever engages is not damaged.
The valve is very sensitive. Even minor damage leads to malfunction.
- Always slide valve into the body, secure it against falling out and never exchange it.
- Loosen marked bolts (quantity 12) - arrows -.
When loosening other bolts, function of the valve body will be influenced or valve body splits up.
- Remove brackets - 1 - and - 2 -.
- Disconnect valve body and remove.
- When removing valve body, pay attention to the damper pistons - 2 -.
- Remove pistons with spring.
Valve Body, Installing
To make sure that the lines do not get pinched during installation:
- Route and attached the wires - 1 -, - 3 -, - 4 - and - 5 - as shown in the illustration.
Distance - a - must be observed so that wiring harness - 5 - does not make contact with planetary gear and then would be damaged while driving.
The valve body is secured with bolts with three different lengths.
- Sort bolts according to length before installing valve body.
- Coat damper pistons - 2 - with ATF and install the spring.
- Insert valve body carefully and secure it using 2 bolts.
Bolt lengths and locations on the valve body
- Make sure the lines are not pinched.
- Install remaining screws and bracket - 1 - and - 2 - and counter turn by hand.
- Install Transmission Fluid Temperature Sensor (G93) and tighten, tightening specification => [ Valve Body Tightening Specifications ] Valve Body Tightening Specifications - Gears, Hydraulic Controls.
- Connect connectors (quantity 8) to the solenoid valve => [ Line Routing, Connectors and Bracket on Valve Body ] Line Routing, Connectors and Bracket on Valve Body.
- Connect bracket for connectors => [ Line Routing, Connectors and Bracket on Valve Body ] Line Routing, Connectors and Bracket on Valve Body, tightening specification => [ Valve Body Tightening Specifications ] Valve Body Tightening Specifications - Gears, Hydraulic Controls.
- Connect connectors
- Attach valve body from the inside toward the outside diagonally; tightening specification => [ Valve Body Tightening Specifications ] Valve Body Tightening Specifications - Gears, Hydraulic Controls.
- Install shift lever.
- Tighten nut for selector lever - 1 -, tightening torque => [ Valve Body Tightening Specifications ] Valve Body Tightening Specifications - Gears, Hydraulic Controls.
- Carefully hold shift lever - 1 - in place using pliers - 2 - so that torque is not transferred to Multi-Function Transmission Range (TR) Switch (F125).
- Bend securing plate on nut up.
- Remove oil strainer => [ Oil Strainer ] Service and Repair.
- Install oil pan => [ Automatic Transmission Fluid Pan ] Service and Repair.
- Add ATF, check ATF level and top off => [ ATF Level, Checking ] Testing and Inspection.
- Connect (VAS 5051) and advance program until " Function/component selection" is displayed.
- Then press "Powertrain (Repair Group 01; 10 to 26; 28 to 39) ".
- After that "6 Spd. Automatic Transmission 09G".
