You could possibly have a broken tranny mount. The fluid should be pink and smell kind of sweet. If its brownish and/or smells burnt you should get it flushed, but only if the tranny hasn't started to fail already. Many people have reported changing fluid on an ATX only to have it fail soon thereafter. Searching the Transmissions forum should turn up more about the fluid flushing topic.
EDIT: I should also add that from what I remember reading in the Transmissions forum, there's no easy way to change the filter unless you disassemble the whole tranny.
