Early Upshifts are typical for high vacuum, and you'll appreciate that.
Vacuum mod valve in case is prone to stick: pull modulator to access the valve; pull valve and 320 grit the valve in a drill press. until it slides in the case without binding. Turn vac mod screw ccw about 2-turns if you never adjusted it. Govenor outer weights are to be left alone. Govenor inner weights should be the short metal tabs (in chevys) compared to stock pontiac TH400s, and the springs should BOTH be flimsy. Pontiacs will have 1 medium tension and 1 flimsy tension. A govenor with high inkstamp number: 21, 23, 25, 27, 29, will be all set as stock compared to PMD govenors like 11, 13.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
