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.

Favorite daily use watch
Color: Blackout
Literally the best watch ever. Super durable. This is my second or third one. The Battery will last years at a time and doesn't take an expensive battery. The buttons are laid out intelligently and are intuitive to use. The strap will eventually break before the watch itself will. Though it has all the stop watch features, it's not too bulky. Also, it takes the time easily and keeps it.

No complaints after use
Color: Black/Yellow Accent
Always been a fan of Ironman watches especially the original. The negative display threw me off for a few days but getting used to it. Love the fit and size of it. Not to mention it's extremely light and you barely notice it after a bit. For under $40 if it malfunctions in a year or two I'll just buy another or one similar.

Bang for the buck
Color: Blackout
Let me previce this review by stating that I have had multiple fitness watches including Garmin suunto Timex and Casio. This watch has some limitations and I will get to them. The first thing is the design and functionality. The picture doesn't do this watch justice. It is sleek. Small enough to not be gaudy. But large enough to look appropriate regardless of your body size. I am 6' 180 lbs and its perfect. The functionality is great. Some watches require a college degree but this watch is simple to program and switch through modes. It has a lap counter countdown timer stop watch as well as time day date etc. It also has more features that don't interest me for fitness so I won't go into them. One complaint other reviewers have stated is with the black background it can be difficult to see display. To them I would reply the top right button is a light. Push it once to illuminate the display. Problem solved. Having a black background does make the display less visible. That's obvious to me but perhaps not everyone. With that being said I only have to use the light if I'm in a dark area. In normal room lighting it is easy to see. This watch does not have GPS capabilities which other watches I've had has. Add another zero to the price of this watch and you can have GPS too. I use this watch mainly for indoor fitness inc swimming and running on an indoor track and use my garmin outdoors. This is a great everyday watch and a great price. No issues no complaints.

6 years and still going
Color: Blackout, Color: Blackout
Owned for 6 years and still going strong. Worn daily, including showers. The only time I take it off is to sleep. The face is scratched up and some buttons worn smooth (I wear it on the inside of my wrist). A few tiny cracks are beginning to form on one of the wristband pieces. Replaced the battery after about 3 years. It has three alarms and I use them regularly. You can choose to set each alarm for daily, weekdays, or weekends. I also use the timer a lot. Indiglo gets used every morning and many evenings. You can disable modes that you never use, so you only see what you want. I never use chronograph, so I have that disabled. Incredible watch.
