When your 6.7L Cummins is towing, hauling, or working in hot conditions, transmission heat can build quickly. This Fluidyne High Performance 68RFE Transmission Fluid Cooler is designed to give Dodge Ram 2500 and 3500 trucks more cooling capacity than the factory setup, helping the transmission stay cooler and more consistent under load.

Built with aluminum stacked plate construction, this dual-pass cooler provides four times the core area and four times the fluid capacity compared to conventional tube-and-fin designs. That added capacity helps improve heat dissipation, support better transmission fluid temperatures, and promote longer transmission life during demanding use.

This cooler is a direct bolt-in upgrade made to fit into the existing cooling system with minimal modifications. With -8 AN female O-ring fittings, a silver powder-coated finish, and Fluidyne’s proven cooling experience, it is a strong reliability upgrade for Ram HD owners who want better protection for daily driving, towing, and heavy-duty work.

European oil… Japanese engine… zero regrets 🇪🇺➡️🇯🇵

Yes, I know what the label says. “European Car Formula.” Yes, I put it in a 2002 Subaru WRX bugeye with an EJ257 block and EJ205 heads. And yes—this oil absolutely slaps. This engine is not stock, not delicate, and definitely not living an easy life. It sees spirited driving, boost, and the occasional questionable decision. After switching to Mobil 1 0W-40, cold starts are smoother, oil pressure is rock solid, and the motor just feels happier. No weird noises, no drama, no oil consumption surprises. The viscosity is perfect for a performance Subaru build, especially if you’re running tighter tolerances or want strong protection under heat and load. It’s thick enough when hot, flows great when cold, and inspires confidence every time I turn the key. Is it technically “European”? Sure. Does my Subaru care? Not even a little. If you’re running a built engine, turbo setup, or just want a proven, high-quality oil that punches above its weight, this stuff earns its reputation. My bugeye may not be European, but it’s living its best life on this oil. Would absolutely buy again—passport not required.

Works if you need help. Not a miracle in a bottle.
Size: 1 Count (Pack of 1)
It has worked every time I've used this product. Won't fix a damage catalytic converter but will help you pass the test if your car almost passed.

Worked like a charm.
Size: 1 Count (Pack of 1)
Used it as directed. Down to an eighth of a tank. Poured it in and added enough gas to get back to one half a tank. Wanted to get it mixed in really well. Immediately jumped on the interstate and ran 75 MPH for 40 miles. Stopped and filled the tank and when I restarted the engine, the light was off. Coincidence? Not a chance. Light had been on continuously for weeks. AutoZone said I needed a catalytic converter. Nope. One thing I found out the hard way. If your gas filler has a flap at the top, make sure it is easy to push aside. Mine had a little release button near the top that the filler hose would depress before the flap would release. Dumped the first bottle right on the ground. Twelve bucks wasted. No one to blame but me, I guess. Still a bargain, even at twice the price.
