Hooked up a batwing to my m7040 and now my loader works about half spoken and only creeps down Also lost 3 point function. I have unhooked the batwing and still having the same issue. Any suggestions on how to fix it. I have changed the oil and filters on the transmission/hydralic system with no luck. Am I missing a filter or something. I canged both of them on the right side on the side the transmission
