Cut off one the heads of the factory "nails" and
remove. Note numbers on inner weights and
color of springs. Consult provided recalibration
kit chart. Choose a route similar to that
of the stock set up. Remove and replace
one side at a time.
The weights act on this plunger, which
opens and closes a passage in the valve
body to control full throttle upshifts.
At left is the stock
spring and weight, and at right is the
lightest spring and weight provided in
the recalibration kit.
To change inner weight
first place weight inside outer weight,
then install spring between inner weight
and spring perch as shown.
The safe route is to
choose a weight one number up or down from
stock. Weight selection brings shift points
within a range, and spring selection fine-tunes
the selection. Note the difference in thickness
of the two weights.
Place weight and spring
assembly back in governor. Place one e-ring
on one axle and insert into place.
