By Robert EmslieThe reason I’m comfortable with having Hagerty as an insurer is because they really seem to get what the whole old car experience is all about. (Full disclosure: I insure my old cars through Hagerty, but they don’t pay me shit to link to their videos, I just think they’re stinkin’ cool.)
Here we have one of their amazing Redline Rebuild time lapse repair videos; the dismantling and rebuilding of a Ford-O-Matic transmission out of a Bullet Bird. The Ford-O-Matic was a Borg Warner design originally introduced in 1951 and serving with updates for decades after. This one appears to be a medium-length case which, according to Hemmings, makes it more commonly referred to as a Merc-O-Matic. Whatever the moniker, it sure is complicated. That matters little to us since we’re not doing the work. So, sit back and enjoy a little old school automatic innards on a Monday morning.

And that’s a Cruise-O-Matic, descendant of the Ford-O-Matic.
