Mishimoto Transmission Cooler 11-14 GM 6.6L Duramax LML

There are wants and then there are needs, and you need to ensure your transmission is running cool for your Chevy/GMC 6.6L Duramax to perform at its best. Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that.

The 2011–2014 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 a 41% greater core volume, and 73% greater fin surface area than the stock 2010–2014 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 their Lifetime Warranty with Accident Protection for worry-free cooling as long as you own it.
