Description

Our 1999-2013 Chevy Silverado/GMC Sierra performance transmission cooler utilizes a stacked-plate design for maximum durability and powerful cooling. With a massive core that’s 521% larger than stock, and a 278% increase in frontal area, the Mishimoto transmission cooler adds significant cooling capacity to your truck whether you’re towing a heavy load, or low-speed driving on the trail. Internal fins and louvered external fins circulate cool air and fluid throughout the core for optimal heat transfer. Included with the Mishimoto transmission cooler are precision-machined -6ORB quick-disconnects that connect directly to the stock lines, or can be removed allow the use of -6AN lines. We also include a relocation bracket for the ambient air temperature sensor to keep full functionality of your truck. An adjustable mounting bracket makes installing this transmission cooler a breeze in an hour or less. Like all Mishimoto products, our 1999-2013 Chevy Silverado/GMC Sierra transmission cooler is backed by our Lifetime Warranty with Accident Protection for worry-free cooling as long as you own it.
