Having trouble with my T770 lift function. This is intermittent, and it's worse when cold. Seems to be getting more frequent. The lift function gives slow operation. However if it lifts slowly, often I can release the joystick then if I lift again it works normally. Sometimes it may repeat this, but usually after 2-3 tries it works fine. This kind of seems like the electric actuator that moves the valve may have a problem. If this is the problem, how big of a deal is it to replace the actuator? Anything I should know before I get started?
