Description

There's no greater enemy for a transmission than heat. Whether your 1999-2013 GMT800 or 900 Chevy Silverado/GMC Sierra is a dedicated tow vehicle, hardworking fleet truck, or a daily driver, you need to ensure that your transmission runs cool. Luckily, Mishimoto has developed a cooler to do just that.----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.
