‘99 Ford Explorer, A Sick Transmission

Q: I just bought a ‘99 Ford Explorer XLT, with only 130K on the clock. The problem I have is when the car is in drive it seems to jump into neutral and after a few seconds back into gear. This happens intermittently and when the car is cruising along on flat road! Not sure, if the fact that the overdrive lamp flashes most of the time and pressing the overdrive button makes no difference is also a symptom of the problem.

- Simon

A: The flashing overdrive light is a good clue that your Explorer needs a computer check. The check engine light doesn’t need to be on to indicate there’s a system problem. The flashing overdrive light is the transmission’s side of the system asking for help. Have a technician perform a computer check and you’ll be on your way to answering the question of why your transmission is not working correctly.
