5R110 Reverse but no forward gears
06 Ford F350 6.0/5r110 4x4
Truck started shifting odd last night but i continued on home and didn't think much of it, started it up and let it idle to warm up this morning, got up to Operating temp, left home and got about 2 miles down the road and stopped at a stop sign. Take off from the sign and it shifted through 1-2-3 once it hit 3rd it pulled a little then the RPM's shot up like it was in neutral, i let off and tried to give it throttle again and the RPM's shot up again, i look at the commanded gear on my Livewire and it showed 5th? so i pulled over and it stayed in 5th. Tried manually shifting into first, still nothing. Tried shutting the truck off and starting again, it hesitates but goes into first and i let it idle to get moving, tried to give it a little throttle and the rpms shoot up and the Livewire shows it shifted straight to 2nd and quickly through 3rd up to 5th and stayed there. Through out all this i have reverse still. I even tried re-flashing to stock thinking it was a tune issue but still nothing.
So here i am looking for thoughts and hopefully answers
