There's no greater enemy for a transmission than heat. Whether your 2003-2009 Dodge Ram 5.9L / 6.7L Cummins is a dedicated tow vehicle, hardworking fleet truck, or a daily driver, you need to ensure that your transmission runs cool. Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that. Our 2003-2009 Dodge Ram 5.9L / 6.7L Cummins transmission cooler utilizes a stacked plate core for durable and powerful cooling. With a massive 212-percent greater core volume, 244-percent increase in fluid capacity, this trans cooler is a huge improvement over stock 2003-2009 Dodge Ram 5.9L / 6.7L Cummins transmission cooler. The Mishimoto transmission cooler is not only larger than the stock cooler, but more reliable too. When the stock cooler's thermostat fails, it fails closed, bypassing the cooler and returning hot fluid to the transmission. Mishimoto has solved this common issue by making the thermostat in our 2003-2009 Dodge Ram Cummins transmission cooler fully serviceable and easily bypassed for constant cooling. A port located at the top of the cooler provides easy access to the thermostat for servicing in just a few minutes. Replacement thermostats can be purchased individually if neededShipping Notes

Nice vest at a good value
Color: Black, Size: Large
Nice vest out of the bag. Fit is good. I’m 5’10” 200lbs with a bit of a beer belly. I’m not muscular at all. Use that description as a comparison to your own body. I can’t speak to the overall quality and how long it will last but for my use going to a black tie gala this is a really nice vest. Happy with my purchase.

Mixed Review. Let me explain.
Color: Black, Size: Large
I ordered both the light gray and black vests in Large. Each one was delivered separately, not sure why, but a day or to late on one was no big deal. I got the gray vest on time. Label reads "COOFANDY." Fits perfectly. The black vest arrived late. Label reads "PAUL JONES Since 1958." Vest was too small. A different material was used on the back section of the vest, which is common, but not what I wanted. The gray vest was constructed of the same material used on the front. I'm not sure if this was a packing error or what, but I returned the black vest for a refund. The verdict: Great, well-constructed, true fit vest with the COOFANDY label. Not so well-constructed (a couple of the button holes had loose threads), small fit vest with the PAUL JONES label. Be sure to check that label. Five stars for the COOFANDY minus two stars for the goofed-up quality control of the seller.
