Weird transmission problem.
 

Hey guys. I bought late 98 F-250, 5.4 G, 4WD. Only spent $300 to get the truck. Had to replace the steering flange because they messed up the ignition cylinder and flange. Truck didn't run for 4 years. 249K miles, no history available. Got the engine running, no DTCs. D, 3, 2, 1 barely moved the truck forward but, R hauled butt in reverse. Checked transmission fluid it was good and clean. Came back to it a few days later it threw a P0720 (output speed sensor circuit) and I have no reverse, park feels like it wants to move, R is neutral, N is forward, D is forward, 3 is forward, 2 is forward, 1 is forward. The N is full drive. The instrument gauges work but the odometer display is intermittent. What is your guys opinions? Linkage? Fluid? Sensor? Wires?

Edit: I cleared the P0720 code after it came up and it has not returned.

My apologies, it was late when I logged on last night. Would an administrator move this into the correct thread?
