To replace the park/neutral position switch, start by using the parking break, and then move the car in neutral mode. Raise the vehicle and disengage the nut to fix the control transmission lever to the shaft of the manual and then remove the control transmission lever. Unplug the wires connected to the switch and take the bolts that secure the park/neutral position switch to the transmission and do not forget to take out the switch form the manual shaft. If the switch will not slide off easily, then remove the burrs on the outside edge of the manual shaft with a file. Align the switch hub flats with the manual shaft flats and slide the switch up on the manual shaft to the mounting bracket contacts the mounting bosses of the transmission. When a new switch is being installed, it will come with the positive assurance bracket, so the use of the neutral position adjustment tool (J41364-A) will be unnecessary in this case. Mount the switch to transmission using two bolts finger tight then place the neutral position adjustment tool (J41364-A) on the switch ensuring the slot is on the switch align with the lower tabs of the tool. Turn the tool until the upper locator pin is in the line of the slot on the top of the switch, then secure the bolts down to 25 nm (18 ft. Lbs.). Take out the neutral position adjustment tool (J41364-A) if necessary and the positive assurance bracket. Reconnect the electrical connectors to the swich, install the transmission control lever to the manual shaft with the nut, tighten the control lever nut to 25 nm (18 ft. Lbs.) essence. Finally, lower the vehicle and examine the switch for the correct working, assure the engine will only start when in a p (Park) or n (Neural) position; if it does not work properly, replace the switch.
