It is connected to the transmission linkage or directly on the transmission; that is why it is easy to spot during inspection. With the neutral safety switch working just fine, untoward accidents can be avoided. Yet there are some signs that will pinpoint defect on this part. One is when the lever has to be shifted from park or neutral mode in order to get the engine to start. Another is if the car starts in Neutral but not in Park mode. That’s the go-signal for a replacement. Thanks for the information. Better to take your advice for it.
