Question:

I have a 03 Silverado 2500hd, I have a stock transmission cooler, what is the difference between the derale 13960 and the derale 15960? I’m using it to pull a 34 ft travel trailer which is better

The difference between the kits is the size AN fittings that come with either. Aside from that it's the same coolers and the same fans. The Derale Hyper-Cool Remote Transmission Cooler # D13960 comes with -6 AN inlet fittings and the part # D15960 comes with -8 AN fittings.

-6 means the hose is 3/8 inch diameter and -8 means 1/2 inch diameter. The bigger the diameter the more fluid can flow through it. Either are a great option for your truck.
