With so many model years to cover, our biggest challenge would be making one cooler fit them all. But we had a plan.
Our 2001-2014 Chevy / GMC Duramax transmission cooler blog so far has focused on the two stock coolers. We looked at the early, comically small, transmission cooler. We looked at the later, and larger but poorly placed, transmission cooler. Finally, after almost a year of R&D, we get to look at Mishimoto’s solution to the stock coolers’ shortcomings. But first, we need to take a closer look at one more of the stock components.
