When I tap the gas I get a clunk immediately. It isn't totally consistent but it's frequent and reproduceable. Kind of sounds like somebody tapping something lightly with a hammer. I notice it at low speeds if I tap the gas, probably because things are quiet. No noise or vibration during drive or acceleration after the initial sound.

I thought it might be motor mounts but they all look really good. Next guess was the u joint. I'm trying to test it. When I shift to reverse I get a linkage clunk (different) then when I go to neutral and then Drive I get a lesser clunk. I just don't know if that's what I'm looking for or if my results mean anything? Crap clunks.
How else can I test it?
