This type of gearbox doesn’t have fixed gears, but in its place uses a system of pulleys in addition to a belt to supply a seamless selection of gear ratios. As a result, your automobile can obtain optimal efficiency and functionality, specifically in metropolis driving conditions.

These kind of cars are recognized for jerky motor execution at sluggish speeds and higher acceleration in addition to it can crank out large gasoline mileage above a far length.

  This kind of transmission fails to possess the very same diameters and tooth quantities, trigger the equipment to rotate at distinct speeds Which can result in a gear clash. This is one of the significant factors this gear is no longer used.

Every change valve responds to a selected tension selection; so if the motor vehicle goes speedier, the two-to-three change valve will just take about, as the force with the governor is significant more than enough to result in that valve.
