Mishimoto 6.6L Duramax Transmission Cooler

Your 2001-2003 Chevrolet/GMC 6.6L Duramax vehicle demands peak performance, and that starts with a reliable transmission cooler. Mishimoto's direct-fit transmission cooler is designed to ensure your vehicle maintains optimal operating temperatures, providing the durability and cooling power needed for any driving condition.

Robust Design for Superior Cooling

This Mishimoto transmission cooler features a stacked-plate design for maximum durability and powerful cooling. The larger core volume and fin surface area, which are 174% and 192% greater than the stock cooler, respectively, provide superior heat dissipation. The included CNC-machined adapters connect directly to the stock transmission cooler lines, ensuring a leak-free cooling experience.

Easy Installation and Worry-Free Performance

Installation of the Mishimoto transmission cooler is made simple with direct-fit brackets and tailor-made hoses. This ensures a hassle-free upgrade that won't compromise your vehicle's performance. Backed by Mishimoto's Lifetime Warranty with Accident Protection, you can rest assured that your transmission will remain cool and worry-free for as long as you own your vehicle.
