After doing a lot of reading... I'm lead to believe that ALL Hondas (of that era anyway) put out very close to 8208 pulses per mile from the VSS. Since they have different tire sizes (and thus different mainshaft rpms per mph), this suggests to me that the adjustment for tire size is done on the other side of the VSS, maybe via a small gear in the transmission case?

Would changing the tranny cause the speedometer to read wrong?

I pulled the new odometer apart and rolled the counter around to the correct mileage... but I'm not sure if I should use the old speedometer/odometer in the new cluster, the new speedometer/odometer in the new cluster, or if it doesn't make any difference? I assumed there would be a difference since the trims would have different tire sizes but maybe Honda corrected for that somewhere else.
