The Mishimoto Universal Transmission Cooler and Power Steering Cooler Kit is used to cool automatic transmissions and power steering units. Some Mishimoto radiators are available only for manual transmission applications. By using the universal transmission cooler, automatic transmission users have the ability to use our all-aluminium radiators with their automatic applications. Transmission coolers can also be installed as supplemental cooling units for trucks which undergo a high amount of stress due to towing. Many transmission cooler kits use standard 3/8" push on fittings, although you should check your service manual for your specific application.

Whether you're hauling a heavy trailer through the mountains or crawling over rocks in 4WD low, your truck’s transmission is under constant stress—and that stress generates heat. Lots of it. Left unchecked, heat is one of the fastest ways to wear down a transmission. That’s where a transmission cooler steps in. So, what does a transmission cooler actually do, and why might it be time to consider replacing or upgrading one?
An automatic transmission operates by using hydraulic fluid to transfer power, control gear changes, and lubricate internal components. Every time your truck shifts, tows, climbs, or even just idles in traffic, that fluid heats up. Ideally, it stays within a temperature window around 175°F, but under heavy load, temps can climb fast—often past 225°F or even 250°F. That’s bad news for longevity.
A transmission cooler functions as a dedicated heat exchanger, just like your radiator or intercooler. It works by routing hot ATF (automatic transmission fluid) away from
