<VV> PG differences

[Clark Hartzel]

The late models have higher pressure to handle the increased torque and I
know there are orifice size differences as the steel plate between the valve
bodies has a square notch cut into it so the factory could identify it.
The booklet from Bob Ballew? (spelling) describes the differences.  I doubt
the average owner who drives "responsibly" would know the difference but my
drag car will have the late model trans with Ken Arnold modifications to
help it live.
