Overfilled Tranny?
Hi all,
I flushed my tranny about a week ago. I guess I overfilled it a bit because I checked the dipstick today and noticed that the entire white thing at the end of the dipstick was covered in ATF. The tranny was cold. Should I bother draining some out? Any harm done? I've driven maybe 100-200 miles like this.
Thanks.

I would drain some out. It shouldn't be over the lower section (cold level) dimpled area. When over filled you can create aeration of the fluid (foaming). Not good. Also it may puke out the vent hose when it expands when hotter in the summer.

That port doesn't go into the pan area, it is in the valve body. So even if the trans is overfilled fluid isn't going to come pouring out of there.

I realize that. My point is that checking it cold is meaningless. It might show too high or it might show too low, even if the level is correct. If you're not checking the trans when it's warmed up you may as well check the trans level by checking tire pressure.
