Hi. I have experienced a problem with my 2000 Audi A6 2.4 transmission fluid running out due to the seal on the tiptronic gearbox miving away from the housing. This happened after we changed the transission fluid, and pumped back 5 liters, car drove a short distance and it started pumping the ATF out. Can anyone give some advice as to what the cause could be? Could it be too much fluid pumped back in?
