2005 Ford F-250

Transmission problem
2005 Ford F250 V8 Two Wheel Drive Automatic 129000 miles

I just bought this truck used and I am already having problems with the shifting. It sometimse will not shift or shift very hard into 2nd gear. I ran OBD scann on it and it gave me a code of P0982 " Shift solenoid d circiut low" I took it back to the dealer and then to a tranny shop and he told me it is not the the tranny, but an electrical connection from the computer to the tranny. He says the tranny is fine. I checked the fluid and it looked nice and clean, no leaks. Should I be concerned about this or does what he says make sense? Thanks for the info.
