The Bugatti Veyron's transmission had a major leak from a seal during testing, but it miraculously stopped.

A replacement seal for the Bugatti Veyron's transmission is a Bugatti-specific part and cannot be obtained.

The Bugatti Veyron's rear differential is on the same hydraulic oil system as the gearbox, sharing the same oil, though with extra filters.

The Bugatti Veyron's gearbox was received back after 5 months of repair.

The only way to properly bed in the Bugatti Veyron clutch and flush out fibers is to run it on a spin test stand with sacrificial filters.

Every Bugatti Veyron serviced by Furlonger Cars shows a slight 'sweating' or 'mist' of gearbox oil around that area without exception.
