Mishimoto MMTC-DMAX-03SL - 03-05 Chevrolet / GMC 6.6L Duramax (LB7/LLY) Transmission Cooler

Transmission Cooler, Silver, fits Chevrolet/GMC 6.6L Duramax LB7/LLY 2003-2005

Automatic transmission oil cooler designed to regulate fluid temperature and prevent overheating. Enhances transmission longevity, maintains performance, and features durable construction with a precise fit.

There's no greater enemy for a transmission than heat. Whether your 2003-2005 Chevy/GMC 6.6L Duramax is a dedicated tow vehicle, hardworking fleet truck, or a daily driver with a liking for the drag-strip, you need to ensure that your transmission runs cool. Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that. Our 2003-2005 Chevy/GMC 6.6L Duramax transmission cooler utilizes a stacked-plate design for maximum durability and powerful cooling. Aside from It's durable construction, this transmission cooler is significantly larger than the stock core. The Mishimoto transmission cooler boasts a 174-percent greater core volume, and 192-percent greater fin surface area than the stock 2003-2005 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 our Lifetime Warranty with Accident Protection for worry free cooling as long as you own it.

  • Direct-fit for all 2003-2005 Chevrolet/GMC with Allison transmission (LB7/LLY)
  • Stacked-plate construction for maximum durability and superior cooling
  • CNC-machined adapters make it easy to connect Mishimoto cooler to stock fluid lines or AN lines
