Mishimoto MMOC-F Heavy Duty Racing Transmission Cooler, with Electric Fan for Maximum Cooling, Universal Fit

I bought this cooler to support a hydraulic winch installation on my jeep. I had a custom pump fabricated with significantly higher flow and pressure which translates to higher fluid temperatures especially when pulling.This cooler works great and fits nice and tidy behind my jeep JK grille. I used the enclosed hardware and fastened it right to the cross brace, easy peasy. The fan is loud so be prepared and it is electrically noisey; I can hear it on my CB but not on the radio so that's good.It has a lot of surface area and the fan moves a lot of air, my fluid stays warm but not hot even when pulling hard in 95° ambient and maximum load.This cooler is easy and flexible to install, simple to plumb and should be able to keep your oil, steering, transmission or axles cool. It is a great value for the cost and should provide years of quality performance.

You will not regret it trans was always smooth now I can't even phathom the words of smooth due to the product making that an understatement now runs cooler but not to cool even with out the fan I have it tied into the factory harnees so when stock fans come on so does the trans cooler but I also have it tied into and set with a thermostat so when fluid reaches a certain temperature the fan once it has power will engage if it has not reached the set temperature it will not however engage thirdly I have also wired in a manual switch with fuse to just have that if I feel the need to kick on the fan to help the trans cooler cool things down a bit but In my time of owning such a wonderful product she has only kicked on twice due to trans oil reaching my set tempature AWSOME FREAKING BUG KE3P OT UP MISHIMOTOOHH AND DONT FORGET 99.9% OF TRUE MISHIMOTO PRODUCT HAVE A LIFETIME WARRANTY!!!!!

We had a Hummer H2 truck with a transmission that insisted on overheating both in hot weather and while pulling a trailer. Had this transmission radiator & fan combo installed in-line, not parallel, per recommendation of a transmission specialist. Given the H2 doesn't provide room to mount in front of the main radiator, we had to mount it on the frame below and two one side. Even though the location is less than ideal, the fan helps overcome that limitation. The average temp dropped by about 10 degrees. If you can mount it in a better position, you'll likely get even better performance. Our mechanic said the product appears to be good quality. As other reviewers have noted, the fan is fairly noisy, but not enough to be a problem. You'll just notice it in the background when its on.

The media could not be loaded. I bought this a year ago and finally got around to installing it (3/28/25).....it came nicely packed and everything was there. I installed in my 2018 4runner because I was concerned about high temps coming from my transmission....this is mostly due to me off- roading at times. The fan blows VERY strong....and is quiet, which is nice. I would definitely recommend this. One thing to note is that you may have to reverse wires because initially, the blue wire is for positive but the fan pulls the air AWAY FROM the cooler. However, if you connect the blue wire to negative and the black wire to positive then you will have air flowing into the cooler (I know, its fkn confusing). No need to worry about things burning down because I contacted mishimoto and they confirmed (2 different representatives on 2 separate calls) that they designed it this way. Its up to the customer to decide which way they want the air to flow. This thing is nice and now I have peace of mind when I hit trails, or rock crawl or head up hills.

I have a 2013 Ford F-150, 3.5L V6 EcoBoost. I was having trouble towing up steep grades, truck was starting to overheat. I had a new (Freak-O-Boost) aftermarket radiator installed and had this Trans cooler installed at the same time. The fan kicks on with the radiator fan does. The combination of both seamed to have solved my problem. Trailer fully loaded is about 6,200 lbs. I pulled it up Sherwin grade (on the way to Mammoth, past Bishop in CA). If you have driven the 395, you know the grade. This trans cooler did it's job! If you complain about the noise when it is on, I suggest you drive a Prius then. Fan turns off once temps drop. Good product.

Lowered my trans temp 30 degrees, great product however the fan doesn't work, it cuts in and out of you tap it, making the fan useless, can't get ahold of them to send me a new fan, if I could get a working fan this would be a 5 star review. If the seller would contact me and get me a fan that would be great!

Great quality, and very useful for transmission cooler. Fan moves plenty of air through the radiator

Installed on a 95 f350 7.3 with the e40d trans. It's been in for about 2 weeks now and I am very pleased. Trans Temps are down 30-40 degrees from before. Even towing 8k lbs up 8% grades it won't even get within 20 degrees from where it use to run with the truck empty driving on flat ground. Fan is hooked up but havnt had to use it yet.
