A semi-automatic transmission (also known as clutchless manual transmission, automated manual transmission, flappy-paddle gearbox, or paddle shift gearbox) is a organisation which uses electronic sensors, processors together with actuators to execute gear shifts on the dominance of the driver. This removes the postulate for a clutch pedal which the driver otherwise needs to depress earlier making a gear change, since the clutch itself is actuated past times electronic equipment which tin synchronise the timing together with torque required to brand gear shifts quick together with smooth.
The 2 only about mutual semi-automatic transmissions are-
1. Dual-clutch Transmission
2. Sequential Transmission
