If you’re experiencing a transmission temperature increase, noises or poor transmission performance, or a transmission line leak, you could have a failed transmission cooler in your durable Duramax. Or maybe, you just want to upgrade to make your performance that much better, either way, and hopefully it’s the latter, Mishimoto has you covered with the Transmission Cooler that fits the 2017-2019 Duramax.

Mishimotos 2017-2019 Chevy/GMC 6.6L L5P 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 67% greater core volume, and 164% greater fin surface area than the stock 2017-2019 L5P 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 the Mishimoto Lifetime Warranty with Accident Protection for worry-free cooling as long as you own it.

IMPORTANT NOTE:

*Silverado models require minor trimming of the grille to fit.

Great toy that stands up to tough dogs
Size: 5 Pack
When these toys first arrived and I opened the box I was disappointed. They seemed a bit flimsy and were not what I was expecting Boy was I wrong! My dog lived his new toy and it’s has not left his side. Best of all, it’s a tough little toy that can take a beating and keep going. My dog usually tears through his toys in a matter of hours, and I tried numerous toys over the years. I’ve tried Kevlar toys, toy that claim to be very sturdy, he always destroyed them in a matter of hours. This toy looks flimsy, but it’s soft and strong

Dog toy that lasts.
Size: 5 Pack
I've got a heavy chewer on my hands, so I've basically thrown money away on countless "durable" toys that get shredded in minutes. I was skeptical about these, but the "no stuffing" design caught my eye—at least there wouldn't be fluff all over my living room! I'm happy to report that these have actually lasted! My dog loves shaking them around and making them squeak. The crinkle sound is a huge bonus; it really keeps him engaged. The fact that they're lightweight makes them perfect for a game of fetch, and my dog can easily carry them around. For the price, getting a whole bundle of these is a great deal. If you're tired of cleaning up toy stuffing, I'd definitely recommend giving these a try.

Not for aggressive dogs but no stuffing is super!
Size: 5 Pack
I've bought these several times but have the attitude that toys are disposable. One of my hounds will drop right through then to pull out the squeaker before losing interest. My other hound wants to love them. Glad there is no stuffing to get all over the house but they will tear quickly.

worth the price !
Size: 5 Pack, Size: 5 Pack
Best toys for our livestock puppies since they have been getting into our outdoor things which isn’t their faults but i figure I would get these small squeaky animals toys and they are obsessed and love playing tug a war with them! They’re super soft, the quality is amazing cause these puppies are tough chew monsters, love the squeaky sound it makes and the patting are suitable as well! Definitely recommend this especially for the price and how fast shipping was !
