Double Clutch Transmission DCT Double Clutch Transmission Photo Source: howstuffworks Photo Source: Getrag DCT use two clutches, each clutch operate independently One clutch controls the odd gears (1st, 3rd, 5th and reverse), while the other controls the even gears (2nd, 4th and 6th) Using this arrangement, gears can be changed without interrupting the power flow from the engine to the transmission Sophisticated electronics and hydraulics control the clutches and gear like in conventional automatic transmissions

Continuous Variable Transmission CVT Continuous Variable Transmission Drive Pulley Driven Pulley Photo Source: Audi CVT use a belt that runs between two variable-diameter pulleys to give a wide range of ratios and a smooth transition between them. The advantage of a CVT is that the engine can be kept at its most efficient speed while the transmission adjusts to changes in load or road speed. A limitation is that CVT rely on friction between the belt and the pulleys, CVT couldn t yet handle a lot of power

Step-Automatic Transmission AT Step-Automatic Transmission Photo Source: Daimler AT use a torque converter to transfer power from the engine to the transmission AT contains several gear sets, and the different speeds are chosen by engaging electronically controlled, hydraulic clutch packs AT tend to be very smooth in operation, but lose some efficiency (and thus fuel economy) due to the slight slip of the fluid torque converter and driving the hydraulic pump to operates the clutch packs

Automated Manual Transmission AMT Automated Manual Transmission Photo Source: Suzuki Photo Source: wikipedia AMT is the automation of the conventional manual transmission system There is no big change in terms of design, basic principles in AMT as compared to manual transmission AMT manages clutch and gearshift operations with hydraulic or electric actuator Shift shocks in manual transmissions are not eliminated in AMT

Dedicated Hybrid Transmission DHT Dedicated Hybrid Transmission Photo Source: Toyota Photo Source: wikipedia DHT is the solution for Hybrid Vehicle DHT use at least two sources of propulsion: an ICE, and at least one e-machine. Without either of these sources, they are not fully functional DHT can offer several modes, for example serial, parallel, power-split CVT mode, all electric and ICE mode
