Neutral Safety Switch Adjustments: Testing

WARNING: This page is about a different car, the 1990 Dodge Ram Wagon, 1990 Dodge Ram Van, 1990 Dodge Pickup, 1990 Dodge Dakota, and 1990 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. With transmission linkage properly adjusted, switch should allow starter operation in "P" and "N" only. To test switch, remove wire connector. Using an ohmmeter, test for continuity between center pin of switch and case. Continuity should exist only with transmission in "P" or "N".
  2. Check for continuity between 2 outer pins. Continuity should exist with transmission in Reverse only. There should be no continuity between either outside pin or transmission case.
  3. To replace neutral safety switch, remove switch from case and allow fluid to drain. Move selector lever to "P" and "N" positions and check that switch operating fingers are centered in switch opening. Install new switch and seal. Tighten to 25 ft. lbs. (34 N.m). Retest switch for continuity and add transmission fluid.
