    What can happen if you over fill your transmission?

    when it gets warmed up it has potential to spit it out the dipstick tube, onto your hot exhaust, causing it to catch fire and take your rig with it, leaving a pile of burned up useless crap. that would be worst case though.

    Yes it can spit out of your dipstick and cause a fire. Overfilling it will put more pressure on seals and whatnot which could make them more prone to leaking. I overfilled the tranny fluid in my dd because its german and when I saw the dipstick looked a quart low, i added a quart. Well...since its a mercedes, they measure it in pints so it is now about half a quart full. I never bothered to drain it out though because the car has 300,000 miles on it and the extra fluid made the shifts more quick and I kind of like it.

    uuuh, my Suburban along with all my other Chevys are measured in pints as well, not just a "Mercedes" thing

    It depends on how much you overfilled it. Overfilling the tranny some is a trick some of the rockcrawlers use to help the tranny keep prime at very offcamber moments. I typically keep my 700R4 right at the top line or just above it for the angles issue. I have never had it loose prime on me yet. I don't have any leaks that I am aware of. The Tcase leaks like a bastard but the tranny doesn't.

    Learn something new everyday. It does seem stupid that when you look at the specs on transmissions they always say they hold like 12 quarts....but the dipstick measures in pints. weird.

    If you fill it too much the fluid can get air in it, then the shifts start getting funny. But I think you really have to overfill it for this to happen.
