When to Replace Your Transmission Cooler – The Mishimoto Guide

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

With the arrival of the fourth-generation Tacoma and its all-new 2.4L turbocharged powerplant, our engineers jumped at the chance to dive under the hood and get to work. Every new generation brings fresh challenges and fresh opportunities, and for us, that means figuring out where we can improve on OEM design to better serve the drivers who take their trucks beyond the pavement. The expansion tank was one of the first components we had our eyes on.

Like most stock units, it’s made from plastic—a material that works well enough under normal conditions but can show its limits over long-term use. Off-roading, heat cycles, and time itself will eventually take their toll. That’s where our latest upgrade comes in.

Choose Your Fighter – Mishimoto Universal Oil Cooler Kits

When it comes to keeping engine oil temperatures in check, a high-quality oil cooler is essential for performance vehicles and trucks (even those of the electric variety). Excessive heat can break down oil, reducing its viscosity and leading to premature engine wear. To combat this, Mishimoto offers two universal solutions—the 23-Row and 25-Row Oil Cooler Kits—each designed to serve different needs while delivering outstanding cooling performance. Both kits include an 8-inch fan capable of moving 600 CFM of air at 3,000 RPM, ensuring consistent cooling even in low-airflow conditions. But what sets these two oil coolers apart?

The 23-row fan kit is built with a robust 68mm-thick tube-and-fin core design and features strutted

This past weekend, thousands of excited drift enthusiasts poured into Old Bridge Township Raceway Park in Englishtown, New Jersey for the kick-off of the third year of the LZ World Tour. Returning to its roots in Englishtown, where the first round of the LZ World Tour was initially held in 2023, this year fans saw drivers take on E-Town’s Road Course over two days of high-speed tandem battles.

With a sunny but cool start to the weekend, the raceway roared to life as attendees poured into the venue. As the smell of gasoline and exhaust fumes permeated the air, enthusiasts made their way through the car show as proud owners discussed their builds and hurriedly polished their vehicles with microfiber cloths.

Hard Lines, Hard Work – Transmission Cooler for the 2020-2022 Ford 6.7L Powerstroke

With 475 horsepower and 1,050 ft-lbs routed through a 10-speed 10R140 TorqShift transmission, the 2020-2022 Ford 6.7L Powerstroke was designed for serious towing. With big power comes lots of heat, and this is especially true when hauling heavy loads or towing uphill. As impressive as this truck is, heat is the enemy of any transmission, and as temperatures rise, so do problems.

The stock transmission cooler does a decent job of cooling, but if you’re looking to push this truck to the limit, decent won’t do. That’s why we’ve been hard at work developing the Mishimoto Transmission Cooler for the 2020-2022 Ford 6.7L Powerstroke—the first of its kind on the market.

Hot Hatch, Cool Turbo – Performance Intercooler for the 2023+ Toyota GR Corolla

As the Toyota GR Corolla enters its third model year, we’ve been hard at work expanding our lineup of performance products for the rally-inspired machine. The 1.6 liter three-cylinder G16E-GTS engine is the highest power-per-liter output of any Toyota road car engine with each cylinder responsible for 100 horsepower, boasting a total of 300 horsepower out of a remarkably small engine. The engineers at Toyota’s Gazoo Racing Division achieved this feat by pairing the G16E-GTS with a turbocharger capable of 26.3 psi of boost.

Picture yourself on the shoulder of the highway. You noticed the gears slipping a few miles back but decided to ignore it because you were only a few miles from home. Those slipping gears turned into violent lurches, and before you knew it, your 2019+ RAM 6.7L Cummins was sporting a Christmas tree dashboard and that dreaded burnt smell. Your transmission is toast.

But it didn’t have to be this way—if you had the Mishimoto Performance Transmission Cooler, you’d have made it home.

Every owner of a performance vehicle knows the importance of keeping their car running cool, but not everyone knows where to start when it comes to upgrading their cooling system. For owners of the 2024+ Ford Mustang looking to take the next step in performance and reliability for their car’s cooling system, it’s best to start with the basics—the coolant expansion tank.

The stock coolant expansion tank on the 2024+ Ford Mustang leaves a lot to be desired. The plastic construction isn’t just an eyesore, it’s not designed to stand the test of time. After repeated heat cycles the plastic yellows and becomes brittle, leading to a higher risk of cracking and coolant leakage. This risk only increases when the vehicle is driven hard, such as fast laps at the track or hard pulls on the dragstrip.

For truck owners who depend on their vehicle for work, reliability and performance are paramount. Whether your truck is a construction fleet vehicle or a dedicated tow rig, one of its greatest enemies is heat — especially when it comes to the transmission.

Transmissions can generate a lot of heat, especially when towing, driving in rough conditions, and off-roading. This becomes more of a problem when they’re paired to a powerful engine, such as those used in GMT800 and GMT900 trucks, which is why we’ve been hard at work developing our Performance Transmission Cooler for the 1999-2013 Chevy Silverado and GMC Sierra.

Following the immense success of the rally-inspired GR Yaris overseas, Toyota’s Gazoo Racing division needed an offering for the North American market. After years of work—including delays brought on by Toyota CEO Akio Toyoda, who wasn’t initially satisfied with the prototype—their result was the Toyota 2023 GR Corolla. Sharing the unique 1.6 liter three-cylinder G16E-GTS engine with the GR Yaris, the GR Corolla puts out an impressive 300 horsepower and 273lb-ft of torque.

So, what does having one of the most powerful three-cylinder engines in history mean? Well, it means you’re in for a lot of fun. But it also means when you’re driving hard, you’ve got to keep that straight-three engine cool. That’s why we’ve been hard at work developing the aluminum Performance Radiator for the 2023+ Toyota GR Corolla.
