How do you adjust the automatic transmission linkage and neutral start switch on Ford F-250 with C4,C5 and C6 automatic transmission?

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.

What is the purpose of the Neutral safety switch and how can it be diagnosed and repaired for different types of transmissions on Ford F-250?

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.
