DL501(OB5)
7 speed with wet clutch

Used in Audi models with Quattro, like: A4/A5/Q5/A6/A7/S4/S5/RS4/S6 from 2009- until now.

The DL501 is the strongest S-tronic (=DSG) gearbox on the market. Audi designed this gearbox to handle up to 1000Nm of torque at an engine speed of 10.000 rpm. Despite this, the DSG has a lot of issues, especially those produced between 2009 and 2013. The issues are fixable, after some modifications your gearbox should be problem free.

Some unsolvable complains can be fixed with the use of the unique software from TVS-Engineering.

The DL501 can handle up to 1000hp and 1000Nm. (With TVS/DSG software)
