Modern transmissions have synchronization gears, so double clutching shouldn't be necessary on any vehicle less than 20 years old. Although if you grind through the synchros then you will eventually need to double clutch, no matter the vehicle.
Sry don't understand i drive a 18spd here in America. I only use the clutch for 1st and reverse. How is your transmission a 12spd when you only shifted 6 times? Thanks
this is a sincronized transmison, you got to use the clutch at every gear, and you got 3 low speed+3 high speed thats 6 speed, and you can split every gear with the switch on the side and 6x2=12 speeds, i hope it s clear for you now
