Exclamation NEED HELP

I have an 01 f250 4x4 freshly rebuilt transmission. Got the transmission put back in and now the truck won’t go over 45 mph. When climbing a hill the truck will downshift but when the rpms raise the speed drops and you almost roll backwards off the hill. When taking off from a stop the rpm gauge gets to 2000 rpm and bad,y starts sputtering. Let of the pedal and it shifts into second. The same with 2nd to third but not as bad. However in low range things works perfectly. Fluid level is good and not low also od light does flash when it’s doing all this. However if I turn the truck off then back on place it in 4 low I can drive all around and have no od light flashing. Please help as I’m stuck on this and this truck is what I use for my business.

In addition to reading the codes check the transmission harness and connector, easy to bang stuff when installing a trans.
