    REMOVAL & INSTALLATION



    A4LD Transmissions

    See Figure 1

    The Park/Neutral Position (PNP) switch, mounted on the transmission, allows the vehicle to start only in P or N . The switch has a dual purpose, in that it is also the back-up lamp switch.

    1. Disconnect the negative battery cable.
    2.  
    3. Raise and support the vehicle safely.
    4.  
    5. Disconnect the harness connector from the neutral start switch.
    6.  
    7. Clean the area around the switch. Remove the switch and O-ring, using a thin wall socket (tool T74P-77247-A or equivalent).
    8.  

    To install:
    1. Fit a new O-ring to the switch. Install the switch.
    2.  
    3. Reconnect the harness connector to the switch.
    4.  
    5. Lower the vehicle.
    6.  
    7. Reconnect the negative battery cable.
    8.  
    9. Check the operation of the switch, with the parking brake engaged. The engine should only start in N or P . The back-up lamps should come ON only in R .
    10.  

    Except A4LD Transmissions

    See Figures 2, 3 and 4

    Starting in 1995, the switch was used not only for neutral start sensing and back-up light activation, but also as a gear position range sensor. The Powertrain Control Module reads the sensor to determine which gear position the transmission is in, and adjusts fuel and spark timing accordingly. The new switch is called the Transmission Range (TR) sensor.

    To install the Transmission Range (TR) sensor requires a special Transmission Range Sensor Alignment Tool T97L-70010-AH, or equivalent.

    1. Disconnect the negative battery cable, block the rear wheels and apply the parking brake.
    2.  
    3. Place the transmission shift lever in the Neutral (N) position.
    4.  
    5. Raise and safely support the front of the vehicle
    6.  
    7. Disconnect the shift control cable from the transmission manual control lever.
    8.  
    9. Disconnect the electrical wire harness plug from the TR sensor.

    1. Align TR sensor slots using the Transmission Range Sensor Alignment Tool T97L-70010-AH, or equivalent.
    2.  
    3. Tighten the retaining bolts to 7-9 ft. lbs. (9-12 Nm).
    4.

    1. Install the manual control lever to the sensor and tighten the retaining nut to 22-26 ft. lbs. (30-35 Nm).
    2.  
    3. Connect the TR sensor electrical wire harness plug.
    4.  
    5. Install the shift control cable to the transmission manual control lever.
    6.  
    7. Lower the vehicle and connect the negative battery cable.
    8.  
    9. Ensure that the wheels are still blocked and the parking brake is applied.
    10.  
    11. Check for proper operation of the switch. The engine should only start in Park (P) or Neutral (N).

    ADJUSTMENT



    A4LD Transmissions

    No adjustment is necessary or possible on the A4LD transmission Park Neutral Position (PNP) switch.

    Except the A4LD Transmissions

    See Figures 3 and 4

    To adjust the Transmission Range (TR) sensor requires a special Transmission Range Sensor Alignment Tool T97L-70010-AH, or equivalent.

    1. Raise and safely support the vehicle.
    2.  
    3. Block the rear wheels and apply the parking brake.
    4.  
    5. Place the transmission shift control lever in the Neutral (N) position.
    6.  
    7. Remove the nut securing the transmission control manual lever to the TR sensor.
    8.  
    9. Loosen the two TR sensor retaining bolts.
    10.  
    11. Align the TR sensor slots using the Transmission Range Sensor Alignment Tool T97L-70010-AH, or equivalent.
    12.  
    13. Tighten the TR sensor retaining bolts to 7-9 ft. lbs. (9-12 Nm).
    14.  
    15. Install the nut retaining the transmission manual control lever to the TR sensor. Tighten to 12-3 ft. lbs. (3-22 Nm).
    16.
