Review shared from Mishimoto Universal 10-Row Oil Cooler; Red (Universal; Some Adaptation May Be Required)
2016 Sport - Acolon
Only a 10 degree difference
Everything went together perfectly the fittings hoses cooler and sandwich plate are very good quality. I know this is a small unit I mounted it in front of the radiator and trans cooler on my 2016 ram 1500 5.7, I live in Ny so I didn’t want a huge cooler as I feared moister collecting in the engine as I was worried about the truck not reaching above 180 oil temp before I get to work every morning. This is a custom install not a direct bolt on, all in all I’m happy and I can always go bigger next time.

Review shared from Mishimoto Universal Transmission Fluid Cooler; 20-Inch x 7.50-Inch x 0.75-Inch (Universal; Some Adaptation May Be Required)
2015 Rebel - Stunnah
I approve!!
Shipping and receiving was fast. Less than a week from tapping to order. Install was like an hour or so. Very easy. Connected it to my AC condenser. Works like they say. Vegas temp has been in the upper 110s degrees and I’ve been driving daily in this extreme heat. Ram temp all day was lower than normal.

Perfection
I was a little worried about spending this much for a radiator but could not be happier with it from the packaging and shipping to install they take pride in their work and it shows still waiting to start the truck up but is installed and holding fluids
