Model 62-7FD25 forklift with 6800h not moving forward, reverse ok. I have had the valve cover off completely disassembled and cleaned thoroughly. Solenoids ok and tried switching them, no difference. Electricity ok, 14V at both solenoids. Oil level ok. Pressure at M port is about 13 bar at idle, C port about the same pressure when selecting forward or reverse gear. Any other things to try or do I start taking the engine and gearbox out? When I drained the oil it looked red and clean, no junk or sludge came out.
