I changed my tranny fluid in my A4 today. I put a new filter and gasket on the pan. I would say I lost about 5-6 qrts. I put 4 in and drove it alittle. Came back put more in it again until it came out the fill plug. Drove it alittle then put more in until it again came out the fill plug. It seems like the tranny is slipping alittle, and when it goes into OD, it downshifts and upshifts back and forth without stopping. Slower cruiing speeds its ok, alittle slipping. Does it need more fluid. It doesnt seem to wanna take anymore.
