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.
Went easily and works great I originally just naught the drivers side exhaust manifold because I didn’t need passenger side but now I am seriously considering buying the passenger side
Best upgrade to my truck soo far, it keeps my transmission nice and cool and shifting like a champ.
It is a significant upgrade versus the original transmission cooler.
