Michael,
Let me ring in on this one (I'm sure I will be corrected if I'm wrong)
as I learned this trick from an old bus mechanic. With the motor off,
put the shifter into 3rd gear, release clutch. Loosen the two bolts (a
little) that lock the Yoke to the base plate. It's the oval-shaped ring
that surrounds shifter and bushings. Now, GENTLY move the loosened
shifter more in the direction 3rd should be, and I mean a small amount
here, not a lot. Tighten down the 2 bolts that you loosened, start the
engine, and try the shift pattern while driving down the street. If
needed, adjust the same way a little more, and test the pattern again.
You'll know when you have it right, as it will shift easily into all 4
forward AND reverse gears!
Good Luck,
Doug in CT

That explains why it felt like I wasn't shifting fully into gear.
