Review on 🔧 Enhanced Performance Transmission Cooler by BD Diesel - Model 1300611 by Michael Skerving

This lowered the transmission temp on my 2014 Duramax by 20 degrees and it did it without the fan on. I was looking for a way to fully control the cooling rate of my Allison 6 speed and I succeeded. The clasps are very strong. This is not just a tongue welded to the tank, but an extrusion that follows the shape of the tank and is welded on two edges. It's a nice touch considering the life he's going to live under a truck. The 10AN fitting seemed overkill at first, but once the rest of the fittings and hoses were purchased it was exactly what the doctor ordered. The caps on the radiator are not just dust caps. They actually hold air to indicate the device was fitted with a vacuum vest. When I opened the lid to assemble it, I could clearly hear the sound of air rushing into the radiator. Your results may vary, but finding out that this thing is airtight was another nice touch. I WILL be one of them again if I need to.
