My auto/hydraulic trim goes up with no problem: when I try to put it down it goes about 1/4 of the way down and then stops. If I push the motor down a few inches with my hand and hit the trim switch down again the motor will move down a few more inches. It will eventually make it all the way down if I keep repeating this. I changed the oil in the hydraulic oil and it didnt help. The switch is sending power to the pump motor consistantly. Any ideas what can be causing this?
