Hagerty has wowed us recently with a series of awesome timelapse engine rebuilds. More recently, they pulled and rebuilt the three-speed Cruise-O-Matic automatic transmission from a 1962 Ford Thunderbird. We loved that video and shared it with you, but we know that cracking open an automatic transmission for some people is like opening Pandora’s Box. Or like looking at old maritime charts. You know those maps with the sea serpents sketched in the line “Here be dragons?” Basically, automatic transmissions look frightening if you’re unaccustomed to their workings so Hagerty took some time out with Davin, who undertook the rebuild, to explain the video.
It’s a bit like DVD-extra commentary (remember DVDs?) and gives you some great insight. The visuals are stunning enough for the mechanically minded, but for the rest of us, we’re glad for the guidance. Davin brings up a great point in all of this: Items like the intricate valve body were designed with a pen and drafting board, long before 3D modeling or even CAD. The all-hydraulic operation of these automatic transmissions is truly a wonder of applied physics.
Give it watch:
