Mishimoto Transmission Cooler, Chevy/GMC (2006-10) 6.6L Duramax 2500 & 3500 LBZ/LMM

There’s no greater enemy for a transmission than heat. Whether your 2006–2010 Chevy/GMC 6.6L Duramax is a dedicated tow vehicle, hardworking fleet truck, or a daily driver with a liking for the drag strip, you need to ensure that your transmission runs cool.

Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that. Their 2006–2010 Chevy/GMC 6.6L Duramax 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. The Mishimoto transmission cooler boasts an 84% greater core volume, and 125% greater fin surface area than the stock 2006–2010 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 our Lifetime Warranty with Accident Protection for worry free cooling as long as you own it.
