Removing wire harness in transmission
Overview Of Wire Harness:
Note:
^ The adaptation values of the Tiptronic control unit must be reset using the Porsche System Tester when replacing/renewing the wire harness.
1. Remove fastening screw from both connectors -Arrow-.
2. Pull off connectors -Arrows- on the solenoid valves -8-12-.
3. Pull off cable plugs -1,5,13-.
4. Remove wire harness for solenoid valves through opening in the housing -Arrow-.
5. Pull off plug -Arrow- for input shaft inductive pickup -6-.
6. Pull off cable plugs from the oil pressure switches -4,3-.
7. Unscrew fastening screw -Arrow- for ATF temperature sensor -7- and remove sensor.
8. Pull off cable plug -2- for output shaft speed inductive pickup -Arrow-.
9. Remove wire harness for sensors through opening in the housing -Arrow-.
10. Remove electrohydraulic control unit. To do this, unscrew fastening screws -Arrows- and take out the control unit.
11. Remove output shaft speed inductive pickup. To do this, unscrew fastening screw -Arrow-.

Overview Of Wiring Harness:
Note:
^ The adaptation values of the Tiptronic control unit must be reset using the Porsche System Tester when replacing/renewing the wire harness.
1. Install output shaft speed inductive pickup. To do this, screw in fastening screw -arrow-. Tightening torque: 7.5 ftlb.
Note:
^ Screws which are tightened with a torque angle must be replaced with new ones.
2. Install electrohydraulic control unit and screw in new fastening screws -arrows-. Initial tightening: 6 ftlb. Final tightening: 90 Winkel-Grad
3. Plug in cable plug -2- for output shaft speed inductive pickup. -arrow-
4. Install wire set for sensors through opening in the housing.
5. Insert ATF temperature sensor-7- and screw in fastening screw -arrow-. Tightening torque: 7.5 ftlb.
6. Plug in cable plug for oil pressure switch-3,4- and inductive pickup for input shaft-6-A-arrow-.
7. Install wire set for solenoid valves through opening in the housing.
8. Push in the cable plug for the solenoid valves -1,5,8-13-.
9. Screw in the fastening screw from both plugs -arrow-. Tightening torque: 7.5 ftlb.
Subsequent work
Reworking wiring harness
1. Install ATF filter.
2. Unscrew ATF control screw -A- and fill in ATF until a constant discharge is visible at the lifting tube.
3. Screw in ATF control screw with a new sealing ring. Tightening torque: 52 ftlb.
4. Check and if necessary, top up the ATF.
