The 7AT cooler is great. Don't notice any difference most of the time, but running it hard in hot conditions, it stays "normal" better (whereas before once the fluid got really hot, you'd see the 7AT engaging a little sloppier and slower). The oil cooler is definitely a good idea in a climate like Houston, even if you're not going to the track IMHO. The standard little Setrab core Stillen uses (the 19 row) is fine for street and SCCA stuff so far, might want the 25-row for a road coarse (I guess I'll find out in a couple more months).
