Luckily, Mishimoto has developed a direct fit transmission cooler to do just that. The 2003 2009 Dodge Ram 5. 9L 6. 7L

Your Cummins powered Ram is a beast, and you don’t want to kill it’s transmission by letting heat cause premature transmission failure. Whether your Dodge Ram 5.9L/6.7L Cummins 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. The 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% greater core volume and 244% increase in fluid capacity, this trans cooler is a huge improvement over stock 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 with a 5.9L or 6.7L 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 needed; no more replacing the entire cooler if the thermostat fails. Owners in cold climates can still enjoy the fast warmup times that the thermostat provides, while owners in hot climates can choose to bypass the thermostat by replacing it with the supplied stainless-steel bypass plug.

To make this cooler even easier to install and service, Mishimoto saves you the hassle of removing seized fittings. The provided CNC-machined, stainless steel hose barb fittings let you cut to the chase, literally. These fittings and the supplied transmission cooler hose allow you to remove the quick-disconnect fittings and connect the stock soft-line to the Mishimoto cooler.

Like all Mishimoto products, this transmission cooler is backed up by Mishimoto’s Lifetime Warranty with Accident Protection for worry free cooling as long as you own it.

Very sturdy & nice looking! Impressive & functional
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
I needed to divide our living room room in half and create a work room but didn’t want it to be visible so we decided to get this and use it in an L shape. It’s very simple and functional, but it does exactly what I need. I’m contemplating hanging a photograph from a ribbon just to add a little personality to the side that faces the living room room but honestly, it’s much more sturdy than I gave a credit for. I am a full-time reseller so I got foam from the hardware store and covered it in fabric as a background for taking pictures and I have a huge one that’s 6‘ x 3‘ plus another one that’s 4‘ x 4‘ both of which are hanging on the inside of this and it works great. I’m impressed!!

Weigh your options
Color: Grey, Size: 2 Large Panels
It serves the purpose but make sure you stabilize it. It's not a bad product it's extremely light and insecure without something to hold the base in place. Maybe it was just the one I bought but it moved a lotI would just bump it a little and it would fall over. The good thing is It is easy to set up and has versatile usage. Also it's really big. Takes up a lot of space make sure you measure your room first.

Functional not durable
Color: Grey, Size: 1 Large Panel
When first assembled, it looked exactly like the picture. However, over time, the top bar has begun to bow. The metal bars are weaker than I expected. It is still doing it's job providing privacy but the quality is not quite up to par. The height, color, and functionality are all exactly as described. If you need an inexpensive room divider, this is a great option. I don't expect it to last more than a year or two, but I would still recommend this product for those needing something fast, easy to assemble, and don't need for an extended period of time.

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.
