3. Plug in cable plug -2- for output shaft speed inductive pickup. -arrow- (Scheme 118), see scheme 17.
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. (Scheme 118), see scheme 16.
6. Plug in cable plug for oil pressure switch -3,4- and inductive pickup for input shaft -6- -arrow-. (Scheme 118), see scheme 17.
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-. (Scheme 118)
9. Screw in the fastening screw from both plugs -arrow-. --> Tightening torque: 7.5 ftlb. see scheme 18
Reworking wiring harness
1. Install ATF filter. Refer to 37 58 19 Removing and installing ATF filter - as of MY 2003 (Cayenne TIP, Cayenne S TIP, Cayenne Turbo, Cayenne Turbo S, Cayenne S TIO Titan) .
Scheme 119
2. Unscrew ATF control screw -A- and fill in ATF until a constant discharge is visible at the lifting tube. (Scheme 119)
3. Screw in ATF control screw with a new sealing ring. --> Tightening torque: 52 ftlb.
4. Check and if necessary, top up the ATF. Refer to 37 02 35 Checking and topping up the ATF - as of MY 2003 (Cayenne TIP, Cayenne S TIP, Cayenne Turbo, Cayenne Turbo S, Cayenne S TIO Titan) .
