A direct-shift gearbox (German: Direktschaltgetriebe), commonly abbreviated to DSG, is an electronically-controlled, dual-clutch, multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic or semi-manual gear selection.

Dual-clutch transmission
Type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. Often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit.Wikipedia
Twin Clutch SST
Brand name of a six-speed dual-clutch automatic transmission, developed by Getrag for Mitsubishi Motors. First incorporated in the 2008 Lancer Evolution X, and was designed to be a more performance-oriented system than that developed by rival manufacturers, with shorter gear ratios optimized for acceleration.Wikipedia
Manual transmission
Multi-speed motor vehicle transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars, or a hand lever for motorcycles). Early automobiles used sliding-mesh manual transmissions with up to three forward gear ratios.Wikipedia
Automatic transmission
Multi-speed transmission used in motor vehicles that does not require any driver input to change gears under normal driving conditions. Hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque convertor.Wikipedia
Semi-automatic transmission
Automated , but the driver's input is still required to start (i.e., launch the vehicle) from a standstill and to manually change gears. Automatic clutch system.Wikipedia

GM Roto Hydramatic transmission
Automatic transmission built by General Motors and used on some Oldsmobile, Pontiac and Holden models from 1961–1965. Based on the earlier, four-speed Hydramatic, but was more compact, providing only three forward speeds plus a small 8' fluid coupling with a stator inside of the fluid coupling . Oldsmobile, one of the users of this transmission, called the fluid couplings stator the 'Accel-A-Rotor.' The lightweight, aluminum-cased transmission was sometimes nicknamed the 'Slim Jim.' HydraMatic Division calls the Roto a four range, three gear HydraMatic. It counts the stator multiplication at 3.50:1 as a first gear, and when road speed and the two coupling halves speed match, it counts the same gear with fluid now passing straight through the stator as 2nd gear at 2.93 to one. Second gear (or third range) has a ratio of 1.56 and because the fluid coupling is drained for this gear ratio making the front clutch apply makes this a rare automatic that is in FULL mechanical lock-up (coupling drained) in second gear.Wikipedia

How does DSG work?
Do I need a direct shift gearbox?
Parkers explains the tech

DSG is a form of automatic gearbox developed by the Volkswagen group, so you'll see it offered across the VW, Audi, SEAT and Skoda ranges.

Direct Shift Gearbox Oil

It uses two clutches to change gears extremely quickly, making for imperceptible cog-swaps. The system is often accompanied by steering wheel paddles to change ratio manually.

How does a DSG transmission work?

The Gear Box Transmission Parts

The system uses two clutches to move up and down through the gears. As one clutch has the current gear engaged, the second clutch prepares the next gear for selection, significantly reducing shift times.

The driver can override the automatic selection of gears using the gearlever or paddles located behind the steering wheel, if they’re fitted.

Do I need it?

If you’ve got your heart set on an automatic gearbox, the DSG unit is one of the better versions available. Bear in mind though that, like all automatic gearboxes, repairs can be very expensive if the transmission goes wrong.
