If the shifter is sloppy, you most likely just need a new shifter seat or if it still has the L-43 trans, there is a set screw that probably just needs to be tightened where the shifter connects to the shift housing. That was the problem with mine, so I pulled the set screw, cleaned it and lock-tighted the
out of it and tightend it as much as possible. Now it doesn't fell like it's in neutral when it's in gear.
