Olred, the flush machines only use like 20psi. Thats nowhere near enough to bend torque converter fins. I would say you already had the chunks. When the flush was done it moved some small pieces through your trans starting the noise. The machines work well for cars that are seviced every 30k. You should never do a flush on a trans that has never had the fluid changed and is coming up for its 3rd scheduled service.
