I had one do that once the hydraulic pumps were bad.

Looks like you have proximity switch problem?

 Be sure that the quarter turn valve at the top end of the dif cylinders is open. Is the spool on the brain moving from one side to the other at the end of the stroke? If not, check that the shift solinoid is working. Try cycling the pump manually, not just with the hand valve, override the cycle solinoids and try shifting over manually. What are the accumulator and pump pressures reading when it tries to shift?     

Hope one of your cylinders are not full of concrete,from someone not cleaning right.

i got no pressure ,driver side will do a full stroke till passenger side will go back to top but wont go back down to hopper,to go back down i have to put pump in reverse,,

yes brain is moving side to side but if i want to continue stroke back down( Passenger) i have to do it manually,,,

just to let you know it was the sensing valve on top between both cylinders,
