2001 ford excursion will not shift into gear

Unread post by ronnyr » Wed Feb 16, 2011 10:11 am

I have a 2001 ford excursion 4wd 7.3 liter auto trans. When I back out of my long driveway, often it will not drive forward once I shift from reverse to forward (as if it were in neutral). At this point, I can shift down into low/#1, turn overdrive off and it will lunge forward a foot or so at a time enough to get me out of the road at which time I disconnect the batteries to reset the "brain" and it will return to normal. It's obviously some sort of sensor or backing safety issue, any help/diagnosis would be very appreciated.

Could be a problem with the valve body in the transmission. But that would not explain why disconnecting the battery makes a difference. Inside the valvebody are all the shift valves and solenoids. If a valve were sticking, this would give you the problem from reverse to drive you are having with your Ford truck. Disconnecting the battery could be resetting a solenoid, but not a valve. A scan of the computer codes that may be stored might be needed as a first step to diagnosing this problem.
