One more tidbit. I do not run any trans cooler at all in my TS car. We have a Meziere billet trans pan on my glide. It circulates water through the pan to cool the fluid. It works very well, even when hot lapping. My chiller circulates that water as well.

Here is a photo of 15 minutes with 78 degree water. Chiller turned completely off completely so this is from a dead start and I do not have refrigeration unit turned all the way down.
