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

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.

Every car with a manual transmission contains a neutral sensing switch that sends information about the car's status to the neural computer situated in the vehicle; this computer will start the vehicle only in the N position, and to disconnect the switch, you have to first, unlite the car battery and then lift the car. Put the transmission in any gear other than N, wipe the vicinity of the switch and then take it out. For Installation: Fix the switch and torque it in the range of 8-12 Ft. lbs. (11-16Nm), reconnect the harness connector to the switch, lower the vehicle, reconnects the negative terrestrial battery cable.

The automatic transmission linkage should be properly adjusted.

Manual transmission switches are closed by the clutch pedal assembly when the clutch is fully depressed. There are two types of manual switches: clutch pedal mounted (early models) and clutch master cylinder mounted (later models).

The MLPS retaining bolts should be tightened securely.

The remainder of installation is otherwise the reverse of removal. If necessary, drive the vehicle to a dealer and have the DTR sensor realigned.

You should ensure that the steering column lock allows the key to go into the Lock position only when the shift lever is in Park.

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

Carefully remove the switch and O-ring using Ford socket tool T74P-77247-A. The switch can be unscrewed after unplugging it, but it is very fragile, so a special socket is recommended for installation, if possible.

The jackstands should be removed and the vehicle should be lowered.

The transmission selector lever should be in Neutral.

Manual transmission switches are closed by the clutch pedal assembly when the clutch is fully depressed. There are two types of manual switches: clutch pedal mounted (early models) and clutch master cylinder mounted (later models).

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

Carefully remove the switch. Caution: It is easy to crush or puncture the walls of the switch. A special socket, designed to remove the switch without damaging it, may be available at your local auto parts store.

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