Jim's right, if it only happens when you pull the lever backwards(2,4,rev)sounds like it needs clamped up as the rod isn't pushing forward as you pull the gearstick backwards.Put it in forward gear(1,3)and clamp the bolt on the rod up.Trial and error or a garage,I would go for trial and error.Wet,cold,and dirty,but you will save money!
