VW DSG direct shift gear transmission and Audi S tronic FAQIntroduction. This article discusses the basic procons of the DSG, how a DSG works, and common problem areas with the DSG. S tronic is Audis name for DSG. At the bottom are some review videos of the DSG. To differentiate between the DSG and a conventional planetary gear torque converter automatic transmission, Ill call the conventional auto a slushbox. Tiptronic is a term used by VW and Audi and only refers to a non manual transmission that lets you shift the gears with the shifter. Below is a cutaway showing the manual transmission type gears and dual clutch system of the DSG. Make sure to also read page 2 of the DSG Stronic FAQ for more technical pictures, how it works, and videos. Summary of DSG operation. VWs direct shift gearbox DSG is a 6 speed dual clutch manual like transmission that automatically shifts. It has internals similar to a manual transmission with a brainvalve body called mechatronics which shifts it. Depending on the model, VWAudi and Borg Warner currently make DSG transmissions. Its better than a conventional automatic transmission and great on turbo cars because the more consistent power delivery keeps the turbo spooled up. The main disadvantage vs. The fluid and filter should be changed every 4. How to change your DSG or S tronic fluid As of 2. VW Auto Group has made around 3. DSG transmissions. Almost all are made in Kassel, Germany with a few made in Dalian, China. The DSG was first introduced to the US in 2. New Beetle TDI and Audi TT. The gasoline NB still used a slushbox for that year. VW Jetta TDI starting in 2. DSG. Premium trim cars equipped with slushboxes had a rolling change to DSG across the VW model line over the years. If the car is premium trim, it should have a DSG. Base cars usually still come with a slushbox. Subscribe and SAVE, give a gift subscription or get help with an existing subscription by clicking the links below each cover image. Steering wheel paddle shifters for TDI with DSG were introduced in 2. The stock gear selector looks like a normal automatic gear selector with park, drive, sport, etc. Archery Software Free on this page. All DSG cars should have a DSG badge on the gear selector. Pictured below is an example from a 2. New Beetle highlighting the badge. The gear selector has PRND positions just like an auto slushbox.

Both DSG and slushbox may have the tiptronic position. Some have said that the DSG transmission learns your driving style but this is technically incorrect. The DSG transmission shift behavior adapts to variables like internal wear, D or S mode, and other input factors like throttle position and rate of change, uphill or downhill, and applies these variables over an existing shift map. Learning is the wrong term since it means new knowledge that wasnt there before the transmission cannot learn anything new, it just applies variables to existing maps. Some engineer has already determined and tested how the shift maps and variables will react. There is no single input field driving style. The perception of a reaction to driving style is the result of the change in a number of variables applied to the shift maps. So yes the transmission adapts but not how most people think. Although learn might be used in marketing literature, its not the right word to use when describing technical operation. This article focuses on the 6 speed DSG found in North America but there are also 7 speed DSG for front wheel drive transverse layout and longitudinal DSG for rear wheel drive. The 7 speed transverse DSG isnt available in North America because its limited to 1. The biggest difference in the 7 speed is the extra gear and the dry clutch vs a wet clutch. More gears and the dry clutch should give greater performance and fuel economy but dry clutches arent cooled by fluid and could have limits on launch mode. The torque limit means it wont appear on US TDI engines anytime soon. In any case, TDI have such a wide torque band that a 6 speed DSG is more than sufficient to work very well. Here is a video showing how the Porsche PDK Porsche Doppel Kupplungen, Porsche double klutch dual clutch transmission works. Even though ZF and Porsche developed PDK independently from the Borg Warner developed DSG S tronic, the video explanation works for both. There are also dual clutch shift type transmissions from Mitsubishi made by Getrag with other manufacturers following. Pros and cons of the DSGA DSG is a great transmission compared to a slushbox. If you leave it in automatic mode, its identical in ease of use. Its lighter and has less parasitic power loss. You should also notice faster shifting and better fuel economy than a slushbox. A DSG can also deliver better car performance and smoother shifting than a manual transmission. In fact, the newest generation of high performance sport cars are faster when equipped with dual clutch transmissions, everything else being equal. Since the mechanism never misses a shift and the clutches are almost always engaged, DSG give more consistent power delivery, especially in turbo cars. In a manual transmission turbo car, you normally lift off the throttle during shifts to rev match the engine, interrupting power delivery. Because a DSG only has a tiny gap in power delivery, the engine is kept under load which keeps the turbo spooled up. The DSG also eliminates driver inconsistency in performance shifting. A DSG is also good for drivers with knee problems or family members who dont want a manual or you cant stand their shifting There are some some quirks with a DSG and these are discussed in further detail below. Despite these advantages, I still feel that a manual transmission is better for a skilled driver who doesnt mind shifting. If nothing else, a manual transmission gives the driver the ability to maximize the fuel economy which is one of the strongest points of a TDI. It also costs less and is more tolerant of higher level power upgrades or poor maintenance. A DSG needs consistent fluid changes every 4. See this FAQ article on how to do this 1. DSG DIY fluid change. Conventional manual transmission gear oil can go anywhere between 6. Many independent garages and even some dealerships are not experienced with the service requirements of the DSG because its still relatively new. A DSG will also not let you rev to engine redline because it will force a shift slightly below redline. Some other disadvantages of a DSG are potentially lower reliability, higher replacement costs, and heavier weight compared to a manual. In theory, the DSG on the TDI should give better performance but the increased weight and greater parasitic power loss take away performance compared to a manual. The clutches in a DSG are lubricated in fluid and this creates greater parasitic losses than a dry clutch. So far, the real world difference in performance between manual and DSG when mated to the VWAudi 4 cylinder gasdiesel engines isnt statistically significant and is well within variations in driver, environment, tires, and engines. Power upgrades and the DSGWhile the DSGs official limit is 2. Stock torque on a TDI engine is 1. HPA motorsports built some high power testers for VW and they experienced no unusual problems. They recommend fluid changes every 1. And of course, how much you actually use that available power and towingracing use will effect transmission and fluid longevity. If you have a TDI, the ECU has a torque limiter so that any power upgrades will not go over the DSG limit.
