    i think nissan_eccs was refering to his tranny. let's wait for the auto tranny gurus replies.

    i can name three reasons for the foaming :

    1. overfilled with atf.
    2. wrong type of atf used.
    3. restricted or plugged transmission.

    when was the last time you had a flush?
    if you had, who did the flushing?
    what's the color of the ATF?
    is there some sort of plastic varnish in your dipstick?

    My bet is that you have over filled your tranny with atf. Have it drained immediately cause it would lead to serious problems with your a/t. Foaming or bubbling is one sign of an overfilled a/t.

    Same speculation, overfilled tranny.

    Drain right away.

    I've updated the AT FAQ for your reference.

    other cause of fluid aeration is low fluid, pump is pumping oil and air
