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.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes
