What condition addlows to get the most tranny oil into you tranny.

[blaubenz]

I replaced my tranny oil a year ago (but I have not drive it since). I was always afraid I did not get enough oil into the Tranny. Because I recover almost 5 quarts of oil but I cannot even get 4 quarts back in. I want to add a little more.

As you all know the bmw did not have a tranny dip stick or dip stick hold. And on mine tranny I don't even have a side tranny fill plug. I have a big nut (not the drain plug) at the bottom of my tranny pan (you folks told me that is the fill plug). When it start to dribble it is the right level assuming right temp engine running.

So how do I get more oil in. Should I have it running hotter then normal temp. Running cold. Have it tilted up front tilted up back?

Is there also an alternative way to add tranny oil. Can I add it through the tranny cooler?

Anyone have any ideas?
