That's call DOT gear
You will need the clutch for down shift
up/push is down shift, down/pull us up shift
Because the gear gap is huge(due to high HP and need biggie and stronger gears),
you just need to pull the gear to up shift without punching the clutch
But that tranny sounds even louder than the engine tho =_=
Take a good look of the video, only use the clutch for down shifting
The DOT gear is so popular now, cost a lot less compare to the tiptronic one's
The RX-8 in Rolax, they use tiptronic tranny, it cost over $10k each
