<VV> Powerglide again

[Harry Yarnell]

There's no need for a torque wrench to adjust the low band. Back off (or
remove) the locknut, mark one flat on the adjusting screw with pencil or
Magic Marker (as a reference), and tighten the screw. You want to make the
'tightening' point to be 'snug'; don't honk on it. Then back the screw out 4
turns. Reinstall the locknut, and you're done.
