Its actually a Yale...but really its a Hyster

I bought this truck knowing it had no forward thinking it might be somthing stupid like solenoids or switches, but i checked both, even switching them and still no forward. Before I start ripping it apart i wanted to get somones elses input. I have checked pressures and I get a good 90psi in both directions, and still no forward. I removed the forward and reverse spool and no sticking nothing. I have one wheel jacked and i find it weird that when i put it into forward theres no effort to go into forward or anything, it actually keeps spinning in reverse. To me even if the clutch packs were completely shot it should atleast go in forward or not stop spinning with the wheel jacked. Even in neutral it spins reverse, no power to move the truck, until it is put into reverse then it has the power to move.
