First time using the transmission cooler last weekend. Wife and I did 15 sessions combined over three days. Often going on track within 20 minutes of each other with the car. Since I dont' have a temp sender for the oil - I IR temp read the case. At the end of the first session without the cooler the case was 200 degrees. After using the cooler it never got above 175 degrees. It's VERY effective in keeping temps down. I used the TuneRS kit.

I ran it off an on-off switch for now - but the fitting I posted above is a switch not just a temp sender. It's made to turn on the pump at 190 degrees of oil temp. It's located right off the fitting on the bottom of the trans.
