I just drained the fluid from my transmission pan and only about a gallon went in the bucket. I know a little more is in the pan but where are the other 6 quarts? I think about 4 may be in the convertor but that still leaves a lot to be accounted for. The fluid was full in park, on level ground, at temp after a 30 mile drive.
Oh yeah, it has the stock convertor in it so it holds a lot of juice.
