So you drive your Duramax a little hard sometimes, huh? Well one thing you shouldn’t overlook is how hot your Transmission becomes when you do. Luckily Mishimoto has designed a solution to that problem: a direct-fit transmission cooler for your Chevy/GMC 6.6L Duramax.

This transmission cooler utilizes a stacked-plate design for maximum durability and powerful cooling. Aside from its durable construction, this transmission cooler is significantly larger than the stock core and boasts a 174% greater core volume. Not only that, it has a 192% greater fin surface area than the stock 2003–2005 Duramax transmission cooler.

The included CNC-machined adapters connect directly to the stock transmission cooler lines for leak-free cooling. Direct-fit brackets and tailor-made hoses make installation easy. Like all Mishimoto products, this transmission cooler is backed up by Mishimoto’s Lifetime Warranty with Accident Protection for worry free cooling as long as you own it.
