47RE Trans Fill, When to stop Filling? Till warmed up?

[JAG1]

My trans service isn't due for another 13,000 miles. Just doing a passive flush (drain and fill) since I have the drain plug but, when do you stop filling so you don't overfill? Need to get it to where I can drive it for warm up. Then fill to the right level.

 

 

Thank you to anyone that knows

If you are just doing a pan drain and refill just fill it to just above the low level marks cold and then check it a couple of times once warmed up, should be close and then you only need to add just a bit to top off when hot at neutral idle and not have to worry about being too full from the start.

Check the stick before you drain it and refill to the same mark as ccold.this is what I do on a pan drain and filter change it usually works out with out having to add any more.
