Overview - Transmission Control Module
- Component location: The diagnostic connection for the Vehicle Diagnostic Tester in inside the footwell on the driver side.
- Determine the cause of the malfunction as accurately as possible using Guided Fault Finding , OBD and Test Instruments before starting any repairs on the transmission using the Vehicle Diagnostic Tester.
- Component location: The Transmission Control Module -J217- is at the back of the transmission, secured directly to hydraulic control module.
The following components are integrated in the Transmission Control Module -J217- and can only be replaced together with the Transmission Control Module -J217- :
- Connector to the hydraulic control unit, on Solenoid Valve 1 -N88-
- Connector to the hydraulic control module, on the Automatic Transmission Pressure Regulating Valve 2 -N216-
- Connector to the hydraulic control module, on the Automatic Transmission Pressure Regulating Valve 1 -N215-
- Transmission Input Speed Sensor -G182- and Transmission Input Speed Sensor 2 -G612-
- Automatic Transmission Hydraulic Pressure Sensor 1 -G193-
- Multifunction Transmission Range Switch -F125- (Is also known as the drive position sensor)
- Automatic Transmission Hydraulic Pressure Sensor 2 -G194-
- Transmission Output Speed Sensor -G195-
OBD monitors the Transmission Control Module -J217-.
Removing and installing, refer to TRANSMISSION CONTROL MODULE, REMOVING AND INSTALLING .
- Component location: The hydraulic control unit is attached to the back of the transmission. The Transmission Control Module -J217- is attached directly to the hydraulic control module.
A - Solenoid Valve 1 -N88- connector
B - Automatic Transmission Pressure Regulating Valve 2 -N216- connector
C - Automatic Transmission Pressure Regulating Valve 1 -N215- connector
The OBD monitors the valves.
Removing and installing, refer to HYDRAULIC CONTROL MODULE, REMOVING AND INSTALLING .
- Component location: The Selector Lever Sensor System Control Module -J587- and the Tiptronic Switch -F189- are a single unit -2-, which is clipped to the selector mechanism function unit -arrows-.
Refer to SELECTOR LEVER SENSOR SYSTEM CONTROL MODULE -J587-, REMOVING AND INSTALLING .
- Component location: The Shift Lock Solenoid -N110- -1- is clipped to the selector mechanism.
Refer to SHIFT LOCK SOLENOID -N110-, REMOVING AND INSTALLING .
- Component location: The Transmission Park Selector Switch -F305-, which consists of two reed contacts -1- and -2-, is installed on the circuit board -B- on the Shift Lock Solenoid -N110- -A-.
The Transmission Park Selector Switch -F305- can only be replaced together with the Shift Lock Solenoid -N110-.
- Installed location: the Transmission Range Display -Y6- -arrow- is integrated inside the instrument cluster.
Replace the instrument cluster if one of the transmission range displays is faulty, refer to INSTRUMENT CLUSTER WITH INSTRUMENT CLUSTER CONTROL MODULE -J285- .
- Component location: The Selector Lever Transmission Range Position Display Unit -Y26- -item 1- is clipped inside the Multimedia System Control Head -E380-.
Removing and Installing, refer to MULTIMEDIA SYSTEM CONTROL HEAD -E380-, REMOVING AND INSTALLING .
A programmed value from the Accelerator Pedal Position Sensor -G79- and Accelerator Pedal Position Sensor 2 -G185- (integrated in accelerator pedal module) are saved in the engine control module as a kick-down signal.
- Component location: The accelerator pedal position sensors are integrated inside the accelerator pedal module -arrow-.
The accelerator pedal module must be replaced if the accelerator pedal position sensor is faulty, for the removal and Installation, refer to ACCELERATOR PEDAL POSITION SENSORS -G79 - / - G185 -, REMOVING AND INSTALLING .
- Component location: The Transmission Fluid Cooling Valve -N509- -A- on the left on the transmission.
- Connector
Removing and installing, refer to COOLANT VALVE, REMOVING AND INSTALLING .
