f-250 replaced transmission but...

i have replaced the transmission for a 99 f-250 super duty 5.4l 4x4 , with a 03 transmission and at first i could only go on reverse and now i cant get it to go on reverse just on foward gears , the only difference i saw on the the transmission was two sensors , witch my truck does not have plugs for , what can i do ???

Go to the scrap yard where you purchased the transmission and ask for help.
My 1997 E40D had two plugs for the shift solenoids drivers side about half way up where the width changes are sure these are plugged in on this transmission.
