I have a 1990 Mercury Sable with 129k miles and while driving my vehicle at hi-way speeds it came out of gear and would not engage after letting my vehicle set for an hour I started it back up and went right into gear I started moving and it jumps out of gear. If you can get it to maintain in gear it will not shift out of first..Also you can start the vehicle put it in gear while holding down the brake and you can feel it come out of gear when it happened I managed to get it to a red light in a small town and when I braked it came out of gear....Need Help I replaced the nuetral saftey switch...

Your linkage is not adjusted properly or the valve body is in need of flushing. Have a trans service done and report back

Suggested Repair

Check and adjust the shift linkage, flush the valve body, and have a transmission service performed.

The owner can feel it disengage while holding the brake and already replaced the neutral safety switch. The expert said the linkage may be out of adjustment or the valve body may need flushing, and recommended a transmission service.
