There's no greater enemy for a transmission than heat. Whether your 2003-2005 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.

Nice Purse set
Color: Green
This purse set is nice; I love the color. The main purse is smaller than I thought it would be. But not a deal breaker since I will only use it occasionally to date just once. The leather is soft and does not have a smell. It is worth the money. I have not used the entire set yet. If there are any changes, I will update my review

Great value for a Very nice purse
Color: Green
Well made purse. Love the green color and the extra pieces that came with it. Holds a lot of stuff. 4 stars because I wish the strap was about 8 inches longer. It is a tad uncomfortable as a crossbody because it sits a little bit too high
