If you're into seeing inner workings of race cars, you're going to love this video. It's a full breakdown of a gearbox taken from a 1997 Jordan Formula 1 car, with an explainer on how it all works.
Scott Mansell of the YouTube channel was lucky enough to get his hands on a paddle-shift seven-speed transmission used during the 1997 F1 season inside a Jordan 197. The unit needed rebuilding, so what better way to go about it than to film the breakdown process for us gearheads to see?
As you can see, this Jordan unit looks almost nothing like a funnel-shaped transmission from a road car. Because the gearbox is a stressed member of the chassis (like the engine), it's designed to take high levels of stress and support the suspension, hence the tall, boxy shape. Since the unit is located between the engine and rear wheels, the differential is directly attached, making for a tight squeeze. Mansell removes the differential first, then the gear cluster to explain how the pneumatic shifter works with the gearbox control unit to push the selector forks into each gear. Even if you're not into F1, it's a great way to learn how high-performance transmissions work.
