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.

Lightweight
Color: Black
I’m not crazy about the leather but I love how light it is and all the compartments. I got tired of heavy leather shoulder bags and so did my shoulders. It’s perfect for every day and very roomy. I’m using the shorter strap for ease.
I recommend this bag.

Size matters,t
Color: Wine
The bag that I received was much larger than the picture of the hobo bag. I am going to return the bag because it is too big for me to carry:
