I overfilled my transmission by no more than 1/3 of a quart. I measured what I took out in my containment pan, but I must have over estimated what spilled on the floor. I drove it 20 miles and checked the level in park; it was a little over the full hash mark. I did this a second time and I noticed some foam on the dipstick. What is the easiest way to get the excess out without dropping the pan again?

 

If it's only a "little" over the full mark, that shouldn't cause issues. If you do want to get some out:

You may need to extend the 12" PVC hose.

 

Yeah. I thought about this but wasn't sure it would work. It is a struggle just to get the trans dipstick all the way in on this truck. I have a fluid siphon which I will just get a longer hose for. Thanks for the help.
