There are two other bands in the 722.00 to 722.03 (non-overdrive, four- and six-bolt pan) transmissions; the way to adjust the operational play in these bands is to swap out a little shaft where the band is anchored to the case. These shafts are available in various lengths.

There really isn't anything to adjust on these transmissions for the forward gears, outside of the vacuum modulator and kick-down linkage, which would adjust only the timing and quality of the shifts, not the ability to shift.

A transmission shop can check the operation of the clutch pack by applying air pressure to the passageway from the valve body that the feeds the piston. (You can do this yourself, if you have access to compressed air, and know where to apply the pressure....)
