Tranny in question came from a van with 3.55 or 3.73 (90 E250 that I never saw, so not quite sure) but I am running with a vehicle that currently uses 4.10 gearing in the diffs.

I have been told to 'add weights' to the governor. Is this something I can do myself? Ford parts still available? Should i just try to find a 4.10 governor??

Then I am curious if I should re-visit TV Cable adjustment when governor is changed/modified.

Any insight is appreciated
