PO733 is basically saying that the TCM is seeing a difference between the input speed to the transmission and the expected output speed. In this case it is because you shift it into gear, but the truck doesn't move. It sounds like the internal clutches, or the oil pump have issues. What was it doing prior to replacing the solenoids? The same thing? If yes, then I would put a pressure gauge on it to see if it's the pump or converter causing the problem. If the pressures are correct but no motion then there are internal parts that have failed, with no engagement though it is more likely the pump.
