From memory Garry about 5ltrs maximum, I baught 20ltrs with the pan & filter and still have about 4-5ltrs left after 3 changes. The problem is there is proberly another 3-4 ltrs still in the system, so if you can n ot do a megaflush the you just have to change it a couple of times, or pull one of the lines off and drain some and keep topping up. I wasnt interested in that method.
If I had my time again, I would only do the sump and pan change if your oil was black, if not I would just drop the oil and re-fill it.
Mine needed a good flush, so am happy I did the pan & filter, but personally I didnt feel much difference in the tranny, but really think it was the correct time to change it.
Cheers Ean
