Ford D6RY-7A247-B Switch Assy - Starter Inhibitor

With the automatic transmission linkage properly adjusted, loosen the two Neutral Safety Switch retaining bolts. Place the transmission selector lever in Neutral. Rotate the switch and insert a No. 43 drill bit (shank end) into the gauge pin holes of the switch. The drill shank must be inserted a full 31/64 inch through all three holes of the switch. Tighten the switch retaining bolts securely, then remove the drill bit from the switch. Check the operation of the switch. The back-up lights should come on only when the transmission is in Reverse and the engine should start only with the transmission lever in Park and Neutral.

To raise the vehicle and support it securely on jackstands. Check the manual shift linkage. Place the transmission in the Neutral position. Loosen the two MLPS retaining bolts. Using the MLPS adjusting tool, position MLPS and tighten the retaining bolts securely. Remove the jackstands and lower the vehicle.

The Neutral safety switch prevents the engine from starting when the vehicle is in gear. It's activated by the clutch pedal in manual transmissions and the shift selector lever in automatic transmissions. The switch can be found on the clutch pedal or clutch master cylinder actuator shaft for manual transmissions, and on the driver's side of the transmission. To check the switch, begin by disconnecting the electrical connector and checking for voltage while holding the key in the START position. If no voltage is indicated, repair the harness and check the starter. If voltage is indicated, jump between pins and check for voltage at the starter relay S wire. If voltage is now indicated, replace and adjust the switch.

Chock the front wheels, jack up the car, and support it on firmly based jack stands. From under the car, disconnect the downshift linkage rod from the transmission downshift lever. Apply a little penetrating oil to the downshift lever shaft and nut, allowing it to soak for a few minutes. Remove the transmission downshift outer lever retaining nut and lift away the lever, then remove the neutral start switch securing bolts. Disconnect the multi-wire connector from the neutral switch and lift away the switch. To reinstall, place the switch on the transmission and secure it finger-tight with the securing bolts. Move the selector lever to the 'N' (Neutral) position, rotate the switch, and fit a No. 43 drill bit into the gauge pin hole, ensuring the bit is inserted a full 0.48 in (12.30 mm) into the three holes of the switch. Tighten the switch securing bolts fully and remove the drill. Installation is the reverse of the removal procedure, and it is important to check that the engine starts only when the selector is in the 'N' and 'P' positions. The neutral start switch on the C3 transmission is not adjustable, so any fault will be due to a malfunctioning switch, wear on the internal actuating cam, or faulty wiring. If a fault is suspected, the switch should be replaced with a new one, using a new O-ring seal and tightening to the specified torque.

The neutral safety switch on the C3 transmission is non-adjustable and any fault will be due to a malfunctioning switch, wear on the internal actuating cam or faulty wiring. If the switch is suspect, replace it with a new one. Always use a new 0-ring seal and tighten to the specified torque.

To begin, chock the front wheels and jack up the rear of the car, supporting it on firmly based axle stands or positioning it over an inspection pit. Next, disconnect the downshift linkage rod from the transmission downshift lever. Apply some penetrating oil to the downshift lever shaft and nut, allowing it to soak for a few minutes. Then, remove the transmission downshift lever retaining nut and lift away the lever. Proceed by removing the two securing bolts of the neutral safety switch and disconnecting the multi-wire connector. Lift away the switch. To refit the switch, place it on the transmission unit and lightly secure it with the two bolts. Move the selector lever to the 'N' (neutral) position and rotate the switch. Insert a No. 43 drill into the gauge pin hole, ensuring it goes a full 0.48 in (12.30 mm) into the three holes of the switch. Fully tighten the switch securing bolts and remove the drill. Finally, refit the components in the reverse order of removal and verify that the engine only starts with the selector lever in the 'N' and 'P' positions.

To perform C4 and C5 transmission change follow the steps, First, safely lift the car and support it on jack stands. Release the downshift linkage rod from the transmission downshift lever, smear the downshift lever shaft area with some penetrating oil and leave it for a few minutes then remove the nut and raise off the lever. Disconnect the wire connector of the neutral start switch and pull out the two bolts of the switch then unplug it. For installation, the switch has to be fitted to the transmission with bolts set only loose while the selector lever should be in the Neutral position. Place a No. 43 drill bit into the gauge pin hole about one-half the thickness of the sheet only and turn the switch bolts until tight, then remove the drill. Check that the engine starts only provided that the selector is in Neutral and Park modes. For C3, AOD, and A4LD transmissions, you should begin by removing ground cable from the battery, and electrical connector from the neutral start switch. Unscrew the defects switch and make sure that it is not damaged before replacing it with the new switch then tighten the switch to the recommended torque. Connect the electrical connector and reconnect the negative battery cable and ensure that the engine should start only when the selector is set to Neutral and Park.

Engine can be started in every gear. The engine should only run if the clutch pedal has been stepped on (for manual cars) or when the car is in either Park or Neutral (for automatic vehicles). Ensure that the steering column lock will allow the key to turn to "Lock" position only when the shift lever is in Park. The key must not be released unless it is turned to Lock.

All manual transmission vehicles are equipped with a neutral sensing switch. The neutral sensing switch signals the vehicle on-board computer, which allows the vehicle to start only when the transmission is in N.

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

The PCM uses the signals from the TR sensor for a number of engine and transmission control operations.

Verify that the engine will start only when the shift selector is in the Neutral or Park positions.

Align the Neutral marks on the rotating inner ring and the stationary ring around the periphery of the rotating ring on the DTR sensor.
