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.

Fun treat/toy your dog will love!
Color: Green, Color: Green
I bought this puzzle toy as a birthday present for my dog. She loves it!!! It took her a minute to get the hang of it but now she’s a pro at getting the treats out. It’s durable and easy to fill. I have it for 3 months and there is no damage to it. She hasn’t chewed it but once in a while she will carry it around hinting she would like it filled. The price point is great.

Definitely recommend this product
Color: Green
Very pleased with this item - it is very similar to the Outward Hound brand but less expensive. I chose this product which doesn’t have easily removable parts - they would be a chocking hazard. Overall it seems durable, engaging and chew resistant - as long as your dog is supervised

Needs improvement
Color: Green
The cups are deep enough and the bone has to have the circle to rotate before the bone can move. I had a hard time figuring it out and so has Our dog . There are 4 black rubber parts included but no instruction on what to do with them. After seeing the toy move across the floor, I figured out these needed to go on the bottom 4 corners. Cute, but needs improvement.
