01. The VAG Direct Shift Gearbox - sometimes called the S-Tronic in the Audi range - is the world's first production dual clutch semi automatic gearbox. The system was developed for Audi by BorgWarner for use in the companies Audi TT 3.2V6, and was so well received it is now used in much of the Volkswagen Audi Group range. The DSG is often compared to F1 style automated or robotic manual gearboxes, but differs in some very important ways. The DSG box takes the basic idea of pneumatic clutched boxes a step further. The heart of the DSG comes from the fact it has two clutches. The basic idea being that the gearbox can then have two gears engaged at any one time, one driving the car, the other waiting to take over.
The clutch arrangement is setup for odds and evens, where clutch 1 operates the 1-3-5 gears and clutch 2 operates 2-4-6.
DSG works by allowing the software to decide what gear the car will need next, and then pre-selects it. If you are accelerating, it will have the next gear up, and likewise if decelerating, the next gear down.

02. The system can then watch for a change signal - this is either done by clicking the corresponding paddle by the driver, or if in full auto mode the computer - and the gearbox can then tell the currently disengaged clutch (the one driving) to engage, and at the same time tells the engaged clutch (the pre-selected gear) to disengage. It can be quite arkward to get all the oil out and you really need to leave it draining overnight. Make sure to measure what comes out so that you can put the same amount back in (you'll never get 100% of the oil out of the gearbox). The car must be warm (go out for a 10 mile drive before you change the oil) and also get it level (you'll have to use axle stands). The drain plug is a large hex nut on the right of the gearbox as you look at the car toward the rear. After the oild has been draining for around 30 mins take the filter off (removing the filter before that will mean oil everywhere!). This information was obtained from FTO Tension which is a great Japanese FTO site. The torque converter can be replaced by new clutches or could be omitted completely when an integrated starting clutch is used. The new ZF 8-speed automatic transmission will be used in the F01/F02 2009 BMW 7-Series in the flagship V12 model, and possibly the Rolls Royce RR4 later.
