Basically, the switch is to indicate what gear you are in and functions as a neutral safety switch. Have you had the TCM scanned for codes? Has the check engine light come on? Also, if the only gear that went out is reverse, there is a chance the low reverse band in the transmission has broken.
Have the TCM scanned to see if there are any sensor issues.
Let me know what you find.
