The factory transmission oil cooler on your 2003-2007 Dodge Ram 5.9L Cummins is a liquid-to-liquid cooling unit, utilizing the engine’s cooling system to cool the transmission fluid during warm outside temperatures and warm the fluid during cold outside temperatures. This design is tried and true, and it works. Until it doesn’t. When they wear out and fail, it can leak coolant into your transmission fluid.

Keeps clutter away
Size: 7.7" x 7.7" x 1.7", Color: Black (Metal Silvered)
This works great to corral all my notes I write on post its or small notes. Keeping them hidden from the desk top b/c or the depth but still visible to me. Much better than keeping on the plotter. Looks great in quality .

Attractive, Simple, And Well-Made
Size: 7.7" x 7.7" x 1.7", Color: Orange (Metal Glided)
I use this as a "catchall". A place to stash things like my wallet and keys when I enter the door, so that I don't use them (I had been prone to that!). It serves it's purpose well. It's both sturdy and attractive, and a good size for a "catchall". Recommended for those like me who need such things.
