Self Study Program 56 – Skoda Octavia Direct Shift Gearbox DSG

VAG SSP 56. The automatic gearbox DSG is available in the new Škoda Octavia, designated as Direct Shift Gearbox – abbreviated DSG. The automatic gearbox DSG combines the advantages of the manually shiftable gearbox and the classical automatic gearbox in a successful way while at the same time suppressing their disadvantages.

It can function in two operating modes:

  • fully automatically or
  • with the manual gear selection – the so-called Tiptronic

Shifting occurs fast, completely smooth and soft, without any jolting. It lasts only three to four hundredth seconds. The power transmission from the engine to the wheels is not interrupted when shifting. The gearbox shifts into a sporty shifting mode only at a higher speed and thus makes it possible to fully use the power potential of the engine. It shifts beforehand in the economic driving mode. Thus the fuel consumption is kept at a low level.
