It was a bad flow control valve, part number 520-163. The Raymond master technician said in 30 years he has only replaced one of those.

Check your Proportional Valve

It is possible there is a blockage in the flow control valve.

Manual lowering is limited speed wise.

Since the manual lowering does the same thing it seems more like a hydraulic issue than a electrical issue

If it is proportional lift/lower it could also be the potentiometer.

Depending on the model you may need to recalibrate the joystick.
