Mario, I never received an email from your about that. We've been using the same trans cooler for over a decade with no overheating issues. I wonder if you either have air in the lines / system that hasn't purged, or if there isn't enough fluid in the system (you have to account for the cooler and lines when adding fluid). We've had these on tow rigs in the southwest pulling large trailers without issues, and we know they work. Feel free to pm or email me at sparky@rndfabrication.com / sales@rndfabrication.com.
