Well worth the Money
2010 GMC Sierra 2500 6.6 with 6 speed AllisonDefinitely on of the biggest trans coolers on the market. Install was so simple it used existing holes and fit perfectly and is solid in its home. Will update when is run it for a while and see how it cools. I did do a trans fluid service with TranSynd and a PPE external filter. All in all took 2.5 gallons of fluid for service with larger cooler and filter.

Easy install and dropped temp 30-40 degrees
Install took about 20min, took a hr round trip and seen a big difference in temperature. Highly recommend.

Works very very well
When hauling my 5th wheel trailer over the mountains with my 2007 Silverado Diesel, I would sometimes have overheated transmission oil, up around 300 degrees F. Normal driving temps with flat terrain would give me temps around 147 deg F. Since installing the cooler immediate resulted in cooler temps. Driving around town temps were 100-125 deg. F. The higest temp recorded over mountain passes between Seattle and Bryce Canyon in May was 147 degrees. This cooler is totally worth it. Good quality, easy fit and installment. Now the only gauge I monitor is the EGR, not worries any more about transmission temps.

Need some work if you have a factor power steering cooler
This cooler fits nice and tight and seams really good quality. The issue is the factor power steering cooler mounts with a bolt right where this cooler has to go. I cut off the corner of the power steering cooler that would hit and used a rivet nut and moved the mounting bolt to the side. Fits great with a little work.

Easy install
Easy to install, all fittings needed came nicely packaged. Haven't seen a drop in trans temps as others have, but it works.
