There are wants and then there are needs, and you need to ensure your transmission is running cool for your Chevy/GMC 6.6L Duramax to perform at its best. Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that.

The 2011–2014 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 41% greater core volume, and 73% greater fin surface area than the stock 2010–2014 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 their Lifetime Warranty with Accident Protection for worry-free cooling as long as you own it.

Best socks ever
Size: Large, Color: (100) White / White / Mod Gray
Best athletic socks I’ve bought. I usually buy UA socks anyway and these are the best. Super soft and comfy. Fit snug and my feet don’t slide around in them.

Much much better than the standard sock
Size: X-Large, Color: (001) Black / Black / Castlerock
These socks are superb. Lots of padding in the right places, snug where it should be snug & loose where you don't want it to bind. They are marked with an 'L' for left foot, & 'R' for the right foot (it makes a difference in the fit being perfect. They stay up on your heel & don't slide down

4 lefts vs 2 rights
Size: Medium, Color: (001) Black / Black / Castlerock, Size: Medium, Color: (001) Black / Black / Castlerock
I ordered a set of three. I ended up with four left socks and two right socks lol. Granted it doesn’t matter unless you’re OCD. JEEZ. Love the socks but not the attention to detail the sock company did on matching left/right marked socks.

Hold up to tough wear - definitely recommend
Size: X-Large, Color: (001) Black / Black / Castlerock
These are my teens favorite socks. We've ordered multiple sets. Given that he tends to wear then as slippers I am really impressed with how they hold up. The extra large size is great for bigger feet. They wash well and I didn't notice any shrinkage, fading or pilling. This set is going to college with him.
