7050 hydraulics

I have a customer with a 7050 with a Power shift trans. When it is at wot the hydraulic remotes wont do anything. If you reduce to 2/3 throttle it works fine. I'm not real familiar with theuse. Anybody got any ideas?
 
Several possibilities. Rear end must be full of oil and that is checked by sight glasses on the rear end left of the PTO shaft. Engine off for 15 minutes to check. The sight glasses need to be REPLACED sometimes because they get foggy. Unscrew the top glass to verify oil level. How does the power steering act when at full throttle??????? Did someone just change the left side hydraulic filter recently??... and there's been trouble since then?? 7050's have a Power Director transmission, not Power Shift.
 
It may be a 7040 then. It has no side skirts and i was going with what he told me. It is definitely a power shift transmission. The steering is fine and its definitely full of oil. I am unsure how old the filter is I suppose this is possible but doesn't feel like it because the rest of the hydraulic functions work fine. Three point steering ect. I will change that next time I'm out there. Anything else I showroom for?
 
Then, I'd say you have hydraulic hose or tractor outlet coupler issues, back seating and stopping oil flow when the GPM is at it's highest flow (wide open throttle).
