the deeper pan alone didn't do a lot temperature wise, maybe 15-20deg (which is what they claim it will do), but the added fluid capacity also helps. I think the b&m pan and the truecool max together are a good combo, I wanted to be in the 120deg area which is exactly what I got. The B&M's for the 6l80e are often on backorder it took me 3 months to get mine and I got the only one in stock then it went back to backorder again. lol, it could be different now I was trying to get mine when there were a lot of fires in the area of there business about 2 hrs from me in Santa Rosa I think Hellwig is over there as well a lot of places were closed.
