My car doesn't even have a transmission. Seriously though, a long time ago, I tore down a 1990 Mustang Automatic transmission and rebuilt it myself and, even back then, it was an amazing piece of machinery. The planetary gear systems are really cool. I don't think I completely understood it, but it was a lot of fun. It did take me two months, heh.

I assume you have an EV? Even EVs have transmissions (unless it's some weird niche car that's completely direct drive). They're just vastly simpler than modern automatic/manual gearboxes, usually a single gear reduction.

Model 3. Calling it a transmission is technically correct, but it is extremely simple. It is single reduction gear as you suggested: https://cleantechnica.com/2018/10/16/tesla-model-3-motor-gea...
