What are the key features of the Nissan GT-R's transmission?

I've heard the Nissan GT-R has a unique transmission, but I'm not sure what sets it apart from other cars. Can someone explain its features?

The Nissan GT-R's transmission is a 6-speed dual-clutch system, which allows for lightning-fast shifts and instantaneous power delivery.

In addition to its dual-clutch setup, the GT-R also has a special feature called 'R-Mode Start' which uses the brakes to keep the car stationary while you rev the engine for a high-performance launch.

You can also manually shift using the steering wheel-mounted paddle shifters, giving you more control over the power delivery and gear selection.
