There's no greater enemy for a transmission than heat. Whether your 2019+ Chevrolet Silverado/GMC Sierra 1500 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 2019+ Chevrolet Silverado/GMC Sierra 1500 transmission cooler utilizes a tube and fin design for improved efficiency and heat dissipation. Aside from its durable construction, this transmission cooler is significantly larger than the stock core. The Mishimoto transmission cooler boasts a 266% greater core volume, and 322% greater fin surface area than the stock 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 by our Lifetime Warranty for worry-free cooling as long as you own it.
