HOW ZEROSHIFT OVERCOME EXISTING AMT?
Benefits the merits of both MT and AT
Clear out the demerits of the same
Provides far better performance compared to existing AMT.
WORKING
The Zeroshift rings act as a pair and represent a dog engagement type transmission.
The unacceptable backlash found in dog engagement transmissions is eliminated by splitting the dog into two halves.
