I tend to agree, and if I for sure knew the diff ratio, somewhere near 3.50, I could calculate. These little devices were very common. Dropping the Diff cover to count gears, since I can't recall what it was 2 yrs ago when I changed fluid, is an option.
One question relative to changing the slave gear in the tail housing. Do all these color gears mesh to the same gear on the tranny output shaft? Or does the gear on the output shaft require a swap as well. If so, with the tailhousing removed, can a simple puller pull the gear off the output shaft? Am I over complicating it?
