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 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 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.

Solid, well-made product. I like that you can rotate-to-mount for different situations.
Size: 6FT, Style: 1 Pack
Heavy-duty chord, heavy-duty sockets, heavy-duty metal frame. Works well, and I like the lighted on/off switch. Being able to rotate and mount however needed makes it versatile. As clearly illustrated in the product description, the sockets are *really* close to each other, but that perfectly met my needs - but look for alternatives if you plan to plug in wall-warts and other space-consuming devices.

Before Mounting, Re-look at the photos for bracket position to save frustration!
Size: 3FT, Style: 1 Pack
Good, solid quality feel, fit and finish... BUT, as other comments indicate, the brackets can be confusing. They come positioned inward for compact fit in the box. Remove the mounting screw from the end, then SLIDE the bracket off, position the L-shape away from the strip for mounting and re-insert the power strip. Others mentioned lack of a tool for bracket removal but none is needed, they simply slide off (they don't rotate while seated). I (and others, per the comments) envisioned it mounted with brackets turned inward (as they came in the box) but doing that puts a screw head in the way of fully seating the unit into the bracket with misaligned mounting screw holes. Came back to this ad to look at the pictures and VIOLA -- set the brackets outward and screw holes align for perfect fit! Quite honestly, made me feel like a chimpanzee given a simple puzzle to solve, and I FAILED the test until looking at the pictures! Reading the reviews made me feel a little better, seeing I'm not the only one!! All that said, this power strip provides great bang for the buck. I'm using it to power my desktop computer with a three-monitor display and external storage drives.

Extraordinarily Useful
Size: 10FT, Style: 1 Pack
We use this to plug in all of our chargers (an off brand mini chain saw, off brand mini blower, and way to many (but we love and use them) Ryobi products). The are on a shelf, easy to get to, no cords tangled, no plugging and unplugging. Great decision because this is a great product.

Better for entertainment center
Size: 6FT, Style: 1 Pack
Have it mounted under my workshop desk the mount ability is simple and works good also have my phone plugged in and the ports work good, the length of the cable is good if you want it somewhat far from the outlet only thing is I wish with the design they spaced out the outlets since ryobi’s charging outlets are bricks but other than that zero complaints

Perfect Power Strip Outlet!
Size: 6FT, Style: 2 Pack
Perfect! Great Quality. Outlets are spaced closer together, but it has 12 outlets, which is amazing for our needs.
