DSG Gearbox

With so many manufacturers (Volkswagen golf, Dodge, Audi, Ford and more) now using DSG transmissions in their vehicles, it is important to have a gearbox specialist who knows these units inside and out.

Here at Kaspa transmissions, we have studied, researched and worked on these units to become leaders in this transmission application.

DSG Gearbox / Transmission

What is a DSG Gearbox?

Over the years, there have been similar production units, but they have never been a great success. Vehicles like the Alfa Romeo Selespeed had a similar concept, but they only had one clutch, and the drivability and reliability were not up to standard.

The DSG name applies to the VW unit and takes its name from the German name Direkt Schalt Getriebe otherwise know as a Direct Shift Gearbox.

Some manufacturers have now moved on to call them the DCT (dual-clutch transmission). The DCT incorporates an automatic transmission and a manual gearbox in one unit but uses 2 clutches. Hence the name DCT.

How does a DSG/DCT Work?

The DSG/DCT combines an Automatic transmission with a manual gearbox. The major mechanical components are similar to a manual gearbox with sliding hubs and a range of gears for each ratio, as you would expect to see in a manual gearbox.

A valve body and mechatronic unit, similar to a late model automatic transmission, controls all this. So simply put, you have a manual gearbox, but you do not have to change gears or put your foot on the clutch; it does it for you. But in a much more complicated way.

What makes this unit clever and popular with vehicle manufacturers is its ability to preselect 2 gears in preparation for its next shift.

So, for example, if you are driving in 3rd gear, the DSG/DCT will preselect 4th and 2nd gear to prepare the driver either slowing or increasing speed. This gives a fast, smooth shift speed and results in an improved economy due to less loss of torque and lapses in acceleration.

DSG Gearbox Clutch

The DSG/DCT uses 2 clutches which can either be a wet or dry clutch. They have even experimented with what they call a moist clutch. The dry clutch is very similar to a manual clutch, and a wet clutch looks very similar to an automatic clutch pack.

Common Problems 

The DSG/DCT is a reliable unit, but it is not without its faults due to its complexities and fine tolerances.

Some of the basic, more common problems or symptoms on a DSG Gearbox are:

  • Shudder on take-off
  • Slipping between shifts
  • Missing gears
  • Delayed engagement
  • No Drive or No Reverse

These issues are normally related to the clutch/s and can usually be resolved with a clutch replacement.

Noisy unit?

These units are known for having bearing failures, and in this case, it would require a rebuild.

Other complaints are:

  • Banging/bumping and general “horrible” erratic gear shifts
  • Delayed engagements
  • Check/Fault Lights on the dash
  • Thumping on takeoff or stopping

Another known problem for the DSG is to have faults with the mechatronic/Valve Body. This is a highly complex unit that involves electrics, hydraulics, and a computer (mechatronic). Basically, it is like its brain, and this unit often needs to be replaced.

Due to the complex nature of these transmissions, diagnosis of any of these symptoms is crucial. A Series of checks need to be done first as some symptoms can result from programming, software or servicing.

If you have any questions or need to test your DSG/DCT transmission, need a DSG mechatronic repair, call for a no-obligation free test drive.  With our service and knowledge, you can be assured that Kaspa transmissions will steer you in the right direction with your DSG

Keep an eye out for these four issues in your DSG 7 dry clutch system transmission

If you drive an older Audi, VW, Skoda or Seat vehicle with an engine capacity under 2000cc, you likely have a dry clutch 7-speed DSG gearbox. Introduced in the late 2000s, the 7-speed DSG was popular for being an automatic transmission with the performance of a manual. However, these gearboxes can suffer from a range of common problems – luckily, all quite repairable. Click here for list of the failures you are most likely to encounter in your DSG 7 gearbox.

DSG Gearbox servicing

Servicing is vital for a DSG/DCT. Unfortunately, the service recommendations for these vehicle’s has been ill-advised over the years.  Terms like “lifetime oil” and ”sealed unit” have been used since DSG/DCT transmissions have been on the market. The first manufacturers said they never needed to be serviced but have since changed their recommendation due to early failures and drivability issues. As the years have gone by, the recommendations have gone from lifetime oil to regular servicing. The DSG is a complex unit with fine tolerances and even more complicated electrics, which are surrounded by oil, so they must have good clean, high-quality oil in them.

Nothing lasts forever, especially oil.
