    I extended the 208 and axle vent lines up under the hood, but I cant find where the vent on the 700r4 is. I'm assuming it is up high and I'm just not seeing it. A little help would be great.

    Also, the 700r4 and rear 10 bolt leak a little fluid. The tranny barely leaks, theres just a little fluid on the pan, and the 10 bolt drips a little, but not very much. I was wondering if fluid can get out, will water be able to get in?? Thanks.

    The vent is on the top of the case, just aft of the bell housing ... usually a little plastic tube that sticks out a couple of inches and kind of lays flat against the case.

    As for the leak -- Make sure it's tranny fluid ... my rear seal leak was getting into the bell housing and onto the TC and getting slung around ... looked like it was a tranny leak (other than it was oil and not TF)
