I always decided to run one after I completely fried my transmission. However, I have 2 (yes 2) coolers and I think I may have overdone it.

It completely bypasses the radiator but even on the hottest day, my tranny gauge (sender is in the pan) never goes about 170. On a normal day, I'm lucky to hit 140 or 150.

Now I am afraid of keeping it too cool.
