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.

Great product! Way better than my stock cooler my truck came with! Keeps my truck much cooler on the hot days and while in stop and go traffic and on the trail! Fan is loud but that what you would expect from and high output fan.

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.

Works perfectly in my Tacoma, i can keep track of all my temps

Excelente producto y de buena calidad. Se siente la diferencia en la caja.

Well-made, good quality and flawless transmission cooler unit installed behind the grille/core support assembly on an '82 El Camino to cool a 2004R transmission. Recommended.

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.

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!

Haven't had it fitted yet but looks good quality

Great
