To anyone interested in calculating the speedometer driven gear. Here is the
formula. You must know the tooth count of the drive gear (output shaft of
transmission)
also need the tire circumference in inches
and the axle ratio
First divide 63360 (a constant) by the tire circumference. This equals the
tire rev. per mile
Now here is the formula

Drive gear x axle ratio x tire rev. per mile = driven gear tooth count

I work at ATRA which is like an AMMCO tech center for independent
transmission shops.
This is the formula we use to help our auto transmission rebuilders around
the world.
