Thanks for the help guys. These machines are very new to me. When the control handle is pushed all the way to the lower position, the forks power down very fast. If you back off just a little, the hyd. motor stops running and gravity takes over. The problem is that in that mode it lowers very slowly, even with a load. There is no linkage to the control handle, it's all CAN wiring. The valve is a solenoid valve, mounted on the hyd. pump. There is no fault code. Tilt, side shift and reach operation are normal, but they are on the steering's hyd. system. Any info would be helpful. Thanks, Lee
