Normal
I went back and looked at my old posts when I installed the Bm dipstick and I couldn’t find the one I was looking for, but I am 90% sure I installed the new dipstick while the truck was cold and the fluid did not run out.ATF has a thermal expansion of like 0.0007% per degree C. 70*F to 200*F is ~72*C so that is .0091Quarts per degree C. So cold to hot would be something like half a quart difference.I don’t know the area of the pan at the level of the dip stick, but I could see half a quart making a difference.Anyways I’m tired, been a long day and my math may be off as I did it on my phone while watching a movie.Long story short. I am pretty sure that engine off with transmission cold will not flow out once you crack open the dip stick. Trans hot with engine off will certainly overflow.
