Just curious who has added a transmission cooler to their 1500 (after market), as when we bought our truck there was no max trailing package for the duramax trucks.   I haven't had any high temperature alerts, but we do tow ~6500 lbs most of the summer (rv trailer).   

 

Thanks

Did the PPE cooler on mine but found that the PPE bypass did the most for dropping the trans temp.

Thanks how hard was the install of the bypass valve?

Thanks, yeah the install looks dead easy.  I'll start with the bypass, and watch temps as the cooler may be overkill.
