The hitch control valves are in a housing atop the RH side of the rockshaft housing. The valve is NOT shown in this drawing, but it would sit on the rectangular area at a slant, in the foreground, with the 8 mounting holes visible.
The factory shop manual will have detailed instructions as to how to narrow down the problem to a specific component.
WHATEVER you do, don't mess with the valve on your own, DEFINITELY NOT without a factory shop manual "at hand"!

2.) Possible control valve porblems.
3.) Possible thermal relief valve problems.
How long IS the lift staying up after shutdown, with significant weight on it?
