    I noticed that my radiator overflow bottle has, well, overflowed.
    It seems that for some reason too much fluid has been going into the overflow pipe instead of staying in the radiator. When I popped the hood to check the tranny fluid I freaked out because I saw fluid boiling up out of the resevoir.
    Your help will be greatly appreciated,

    Only two things I have to add:

    I've seen stop-leak do this. It gets into the overflow bottle, and every time water gets in there, it acts as a check valve. Eventually it overflows.

    If you've got air in the radiator when its running (bubbles) you could have a blown head gasket. Not sure that this would push fluid into the overflow bottle, but I guess it could if it increases the cooling system pressure enough.

    Your engine is over heating for some reason.
