Double- clutching is a driving technique solely used in manual transmission vehicles. Essentially, there are two ( or maybe more) shafts, each one equipped with an assortment of bearings, synchronizers, and different sized gears. Then, you disassemble the transmission and remove the offending synchronizer.
They do this by adjusting the rotation of the shafts with-. Synchronizers are devices used in manual transmissions to allow the transmission to shift from gear to gear without grinding. Auto transmissions go out all the time. Powershifting is a process by which a driver can get more power out of their engine by keeping the accelerator pedal depressed while engaging the clutch pedal and shifting gears.
