my 1993 vk540 wont go into all 3 gears, i have adjusted the rod all the way in both directions and i either have high and reverse but no low, or low and reverse and no high, and it slips out once in a while also i checked the journal and there is no signs of wear on it, im thinking about replacing the shift mech with the spring on it to see what that does.... any help out there would be great....
