AG4

The automatic transmission 01N (modification of AG4), developed for Audi A4,A6, Cabrio, can trasfer torque from engines with the capacity of 2.8 liters. These transmissions differ in housings and differentials. Most of other parts are interchangeable. The main peculiarity of these transmissions lies in the fact that the differential has a separate lubrication system which requires special oil. This oil is checked and changed separately from ATF.
