93 ford f350 220000 has a e4od hard shifting problem. It is not it limp mod shifts in all four gears but hard. Check the codes all I got was 23, 23 ,1 ,43 ,43. That's what I got but I could be reading it wrong need help only truck.

did you hold wot koeo during scan? if not,you'll get false code 23.
try reading codes again.43 doesn't seem right...........oh i bet that's where your odd ball 1 came from.im guessing code 14 = tach sensor issue.that doesn't explain your 3 though then in that case.mmm.what do you have for a scanner? are you just reading them with a multi meter? that would explain it.that's kinda tricky.
