Component Location Overview - Transmission Control Module
- Component location: The Data Link Connector for the Vehicle Diagnostic Tester is 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. Refer to Vehicle Diagnostic Tester.
Mechatronic, Transmission Control Module -J217-, Sensor And Pressure Regulating Valves - Part 1
- Component location: The Mechatronic unit is bolted to the bottom of the transmission housing and is covered by the transmission fluid pan.
The Mechatronic unit incorporates the hydraulic control, the transmission control module, the multifunction transmission range switch and the sensors and actuators as a complete synchronized unit. The following are part of:
- Automatic Transmission Pressure Regulating Valve 8 -N510-, depending on the date of manufacture, also Solenoid Valve 1 -N88-
- Automatic Transmission Pressure Regulating Valve 7 -N443-
- Automatic Transmission Pressure Regulating Valve 6 -N371-
- Transmission Output Speed Sensor -G195-
- Automatic Transmission Pressure Regulating Valve 3 -N217-
- Automatic Transmission Pressure Regulating Valve 5 -N233-
- Automatic Transmission Pressure Regulating Valve 2 -N216-
- Automatic Transmission Pressure Regulating Valve 4 -N218-
- Automatic Transmission Pressure Regulating Valve 1 -N215-
Mechatronic, Transmission Control Module -J217-, Sensor And Pressure Regulating Valves - Part 2
- Transmission Input Speed Sensor -G182-
- Transmission Control Module -J217-
- Transmission Fluid Temperature Sensor -G93-
- Drive Position Sensor -G676-
OBD checks all the components named.
Only the complete "Mechatronic" unit can be replaced.
Removing and Installing. Refer to MECHATRONIC, REMOVING AND INSTALLING .
Removing and Installing. Refer to TRANSMISSION FLUID AUXILIARY HYDRAULIC PUMP, 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-.
Removing and installing. 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.
Removing and installing. 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 Coolant Valve -N488- -1- is located on the back of the subframe on the left side.
- Connector
- 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 OVERVIEW - INSTRUMENT CLUSTER .
- Component location: The Selector Lever Transmission Range Position Display Unit -Y26- -1- is clipped inside the Multimedia System Control Head -E380-.
Removing and installing. Refer to LAMPS .
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 MECHANISM .
