Welcome to this forum! I've renamed your thread, and moved it into the transmissions section. Do you have manual 1st gear? Did you check the low/reverse band & servo?

Insert a phillips screwdriver into the low/reverse servo bore, and see if the band has spring action. Check the tip of the low/reverse servo for chips. Did you use a 1/4" drive In/Lb torque wrench on the valve body bolts?

I've been having the same problem. I've changed out the entire VB (complete with new solenoids). I've done the Ford TSB's. I have some sonnex upgrades. New valvebody gasket. Borg Warner EPC. New Reverse servo piston with "D" rings. I've checked to see if the reverse band is there (it is, and it's springy). I have manual 1st, and 2nd (also engine braking). I can also move it to Drive once the truck is actually moving, but once I come to a stop I have to manually shift to 1st and second. I've checked the transfer case moves in both directions. I have the new 4wd module. Fluid is new/good. I disconnected the driveshaft and it was rotating once I put it into reverse. New diff, new diff sensor. The OD light is blinking. I'm totally lost. HELP! (sorry to piggyback on this thread)

A big thanks to anyone that can help.

I heard something about a software update for the PCM. Anyone have any info?
