What is the correct way to check the trans fluid on my 2001 F150, 5.4L with R100 trans? Hot, cold, running, not running, in gear, in neutral? No matter how I check mine, it is higher than full on the dipstick. It has always been this way since new so when I drain and fill, I put back the same amount that I drained. This puts it over the full mark again. So, I'm wondering if this will harm anything.

Check it hot, in park, engine running.

by hot ....means operating temp...

Ok. I drove home from work yesterday, put it in park, left it running and checked it. The level is just slightly into the "do not add" area. Like maybe 1/8". Should I take some out?

No, leave it at that. How does it shift?

Seems a little rough sometimes going from 1st to 2nd. But only sometimes. All other gears are smooth.
