Mishimoto 2014+ Chevy Silverado 1500 V8 Transmission Cooler

If you push your 2014-2019 Chevrolet Silverado or GMC Sierra 1500 V8 hard, especially for towing or in hot climates, keeping your transmission fluid cool is critical. Overheating can lead to premature wear and costly repairs. Mishimoto developed this transmission cooler specifically to help manage transmission temperatures in these trucks.

This cooler uses a stacked-plate design, which is known for being very durable and effective at dissipating heat. It installs inline with your truck's factory cooling system, adding about 0.65 quarts of transmission fluid capacity and over 3,000 square inches of surface area. That's a big jump in cooling potential. The kit includes adapter lines that connect directly to the stock setup, and a bracket to relocate your ambient air temperature sensor. It also comes with CNC-machined mounting brackets and high-grade hoses, making installation more straightforward. A thermal bypass valve delete is included, which ensures fluid flows through the cooler at all times, making it especially beneficial for vehicles in warmer regions.

This Mishimoto transmission cooler is designed to fit a range of GM trucks, including the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, and GMC Yukon. It's backed by Mishimoto's Lifetime Warranty with Accident Protection, so you can install it with confidence.
