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.

Our 2001-2003 Chevy/GMC 6.6L Duramax transmission cooler utilizes a stacked-plate design for maximum durability and powerful cooling.

It's a good look.
Color: Black/Brown/White, Color: Black/Brown/White
Very nice watch. I was complemented twice in 3 days. It fits well, looks great. I'm trying to look at screens less and teach my kids how to tell time on an analog clock face. 4 stars because, while the strap on the outside looks like it's a nylon/fabric wrist band, the inside is leather. My wrist has gotten pretty sweaty as a result. And there is a VERY audible 'tick' involved with this watch. I'm a contractor and have moderate hearing loss, but I've noticed the tick when I'm sitting quietly in my living room. If a ticking clock drives you nuts, I would not recommend. Most of the time, I am in a locale so noisy, it doesn't matter. They want a jeweler to change the battery, which, as a guy who fixes stuff, I don't love, but I've got some time before I think about that. No pun intended. I'm happy with this purchase. Good for the jobsite or a hot date with my wife.
