If you’re towing heavy, daily driving in hot conditions, or just want to keep your 68RFE running cooler and happier, the Mishimoto transmission cooler is a solid upgrade for your 2010–2012 Ram.
It’s a direct-fit replacement that ditches the factory weak link for something built to handle the kind of abuse a Cummins is known for dishing out. This cooler uses a tried-and-true tube-and-fin design, which makes it perfect for heavy towing and rapid load changes, exactly the kind of scenario where stock parts fall short. With a 60% increase in core volume and an 86% bump in external fin area compared to the OEM unit, you’ll see noticeably better cooling performance and heat dissipation. That translates to more stable transmission temps, even when you’re working your truck hard.
One of the smartest features? It can pair up with Mishimoto’s optional transmission line kit to bypass the factory cooler and A/C condenser. That’s huge if your transmission has ever failed and you’re worried about leftover contaminants taking out your rebuild. This kit makes sure your fluid runs clean and cool, whether you're using the stock or Mishimoto cooler setup.
Built for a clean install, engineered to keep temps under control, and designed with towing in mind, the Mishimoto cooler is the peace of mind your Ram deserves.

Durable non see through fabric
Color: Black, Size: 4 Panel-88'', Color: Black, Size: 4 Panel-88''
This room divider is exactly what I need. It is very durable and easy to move around. You can’t see through the fabric. I love it. My reason for purchasing this divider is to use as a divider and as a backdrop holder. And it serves both purposes perfectly. It looks much better in person than on camera. It did have the spots on one side on all of them but in a few days they went away. It foldaway and tucked away easily.

Great product
Color: Black, Size: 4 Panel-88''
Love the look of this after it’s put together. It’s pretty sturdy and the connecting clips allow you to shape it different if you need it to fit in a corner. We use this at work so it’s great for the space we use it in. A little hard to store because it doesn’t fold up nicely because of the feet on it but I’m happy with it overall.

Does its job
Color: Black, Size: 4 Panel-88''
For the price the quality is decent. The only thing I do not love is the panels are attached to each other with 3 plastic clips. Only 1 side of the panel is actually attached to wheels. The other side kind of sits on the bar and is held in place with those clips.
