There’s no greater enemy for a transmission than heat. Whether your 2017-2019 Chevy/GMC 6.6L L5P 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. Our 2017-2019 Chevy/GMC 6.6L L5P 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 a 67% greater core volume, and 164% greater fin surface area than the stock 2017-2019 L5P 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.
