There’s no greater enemy for a transmission than heat. Whether your 2001–2003 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 2001–2003 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 174% greater core volume, and 192% greater fin surface area than the stock 2001–2003 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.

Q:how many quarts of transmission fluid do I need to add after the installA:
Thank you for reaching out to us here at Mishimoto.
After installing the cooler you will want to add approximately a quart of fluid to the system to compensate for the increased volume in addition to the amount lost during install.
