Why correct level gearbox ATF is important

Before 25,000 KM, the ATF was drained and renewed by an Audi workshop.

Now I have the oil pan, goes on the 3.7 yes without removing cat and muffler, taken down to replace more ATF.
The importance of this measure was then demonstrated.
Brownish soup, although I was leaving the 90,000 km old ATF, which ran out like new, now as I said brown soup.
==References====External links== Two liters too little in it.
Black mud was found on the oil pan floor, and the magnets were covered with mud.

Why the oil, when there is too little in it, wears away so quickly, will certainly explain Konno well.

Now with correct filling, the gearbox also runs so softly, that you have to concentrate very precisely on the switching processes to get it.
It's good before, and that's what's precarious.

So friends, always change ATF, best of all, and not the Audi "Battler" (we've seen an A8 before).
