Default Transmission dip stick reading.

Okay so I've searched high and low and haven't found what I looking for so possibly you could be my savior.

I changed the transmission fluid in my STi a few months back and knew I slightly over filled it, minimally mind you. So yesterday being the perfectionist I am, I wanted to take some out so it wasn't over filled.

I jacked up the car on stands and drained a little fluid from transmission bolt (A) or the oil pan side,(not the torx bolt) I then lowered the car back down and checked the stick, no change in level.

For the second time I dumped more out from the same drain bolt and by this time I have filled half of a regular 16.9 oz water bottle. I lowered it down, checked and saw no level change.

I then drove around, let the car sit, and check again and still nothing.

My question is, I know on the oil dipstick it is about a quart of oil from low to full, does the transmission dipstick have some kind of guide I can go by like that? I'm just trying to see how much fluid that I need to drain to lower the level bit.

Thanks

Unfortunately no, the service manual does not give any quantity of oil between the lower and upper marks. It only states that the total capacity is 4.3 qts.

Do you have an appropriate container than you can drain into and still be able to reuse that oil to add back into the tranny? If so, you could test to see how much you need to drain to get some good movement on the dip stick. Then just add to the full mark.

You have already drained 1/2 qt, how much did you put in when you filled it up?

When I did my tranny oil, I overfilled slightly and had no problem draining a little out to get the level right at the full line.

I put in 4 quarts when I filled it so there must've been left over oil. I don't think there should be THAT much oil for which I need to drain. If I take too much oil fluid out, I would just put some back in.

So when I first posted this I had drained a 1/4 qt. and there was no noticeable change, I drained another 1/4 qt. making 1/2 qt. (16 oz.) altogether and it brought me right to where I wanted the level to be. So for roughly 3mm over the full line, I had to drain a half quart. This is rough so I don't know if that is good measure.
