a904 whine noise

I'm not a trans guru bully any means, but that does sound like pump noise to me. When I swapped to my 200r4 it had a fair amount of pump noise and it sounded WAY worse because I had the case of the trans hitting the floor in one place that made the noise transfer inside really bad. It decreased quite a bit when I clearanced the floor. Any chance with the vent stuff and cooler/filter stuff you added you've got interference some place?

Just a thought
