What does it mean to granny shift?

Simply put, granny shifting is when you upshift or downshift through the gears of a manual transmission normally. This means that there's not rev-matching or double clutching happening through your shifts, which also means that the car will likely bog when you downshift.

These computers eliminate the need for the driver to manually change gears and the entire process is automated.

Can you drive a dual clutch like an automatic?

You can't drive a dual clutch just like you would an automatic. Gear shifting may be controlled by a computer and happen quickly, but you'll still need to handle the shifting yourself in order to keep the transmission working properly.

Can you shift without the clutch?

You've probably heard riders blip their throttle as they downshift while rolling to a stoplight.

Does downshifting increase speed?

The purpose of "downshifting", or shifting the transmission down from a higher gear to a lower gear, is so that a driver can accelerate their car as fast as possible when exiting a corner that they had to slow down for.
