Do I Need a Transmission Cooler?

Transmission coolers help to protect your transmission when you turn up the heat.

Transmission Coolers help transmissions deal with the added stress and heat caused by towing boats, trailers and other heavy objects.

Each year, hundreds of thousands of automatic transmissions fail and the majority of them are due to overheating of the fluid.  Most of this overheating is due to today’s vehicles being engineered with downsized engines and transmissions in an effort to maximize fuel economy.  We demand the same or better performance from these smaller, more efficient powertrains, therefore they must work harder than ever before.

For the same reason, the addition of an auxiliary transmission fluid cooler isn’t just necessary for those who tow trailers anymore.  Many manufacturers are now also recommending the addition of a transmission cooler if you carry extra passengers or cargo (ie – vacation, car-pool), drive in stop-and-go traffic, drive in hot or very cold weather, or climb steep inclines.  This would likely be 90% of your customers, just as the above statistic would indicate.

Due to the extra strain placed on today’s vehicles, automatic transmissions require a lot from a transmission fluid.  The fluid must lubricate the moving parts, clean the interior surfaces, protect against corrosion, transmit energy, and most of all, cool the transmission.

When an automatic transmission’s temperature exceeds 200F, the transmission fluid is pushed to its limits. Overheated transmission fluid will break down causing seals to crack, moving parts to clash, and leaks to occur.  At Mister Transmission, we offer our own brand of high-quality transmission fluid coolers (also available at Canadian Tire) and the expertise to install them properly.

Mister Transmission’s aluminum-construction, transmission fluid coolers are among the best in the business.  Our coolers offer maximum heat dissipation by constantly swirling and agitating the fluid as it flows through, and with the addition of our thermostatic flow control we ensure that your customer’s transmission maintains the ideal temperature for shiftability and long-life.

There are many areas under the hood of a modern automobile where you could install a transmission cooler, but there’s really only one location where you will get the full 100% cooling efficiency.  You want to install the transmission fluid cooler in front of all other heat exchangers (ie – radiator, a/c condenser, etc) and in an area with good incoming airflow.

For every 20F degree drop in transmission fluid temperature, you can expect to extend the fluid and equipment life, thereby extending the life of the vehicle.  That’s why it is very important to have a quality transmission cooler, and more importantly, to have it professionally installed.

Mister Transmission recommends offering transmission fluid coolers to all of your customers since this would not only decrease the likelihood that they may suffer a premature transmission failure, benefiting both your customers and your business.  To ensure proper application and function of your customer’s transmission fluid cooler, we recommend you allow the experts at Mister Transmission to install it for you.

If you are interested in having a transmission cooler installed in your vehicle, please contact your local Mister Transmission and book an appointment for our FREE 21-Point Multi-Check Inspection.

Sanjay was amazing and he explained all my problems thoroughly. I had a 2016 Honda pilot with transmission issue and he did a free diagnosis and gave me quotes so I can make an educated decision. If I ever have another problem with my transmission, I will definitely seek out Sanjay.

Pete L.
I recently had my vehicle into the Pembina Hwy location for transmission repair. They did a transmission rebuild in their shop and installed another reconditioned torque converter to fix my transmission problem. Now that I got my vehicle back, the transmission is working like a new vehicle. While there, some parts were replaced for the steering and suspension that were just worn out. Now my ride is much smoother. My experience there was very professional and I felt confidence in their mechanics. The small but dedicated staff were very pleasant and courteous. I was given a courtesy car for ten days while my baby was in the vehicle hospital too. Thanks guys..👏

Bill Martin
I am very pleased with the service provided at Mr. Transmission. We had our transmission break on our 2019 Ford Explorer, and the dealer quoted us 10-12K! I called Mr. Transmission, and they were able to rebuild it for half of the price. Lee was very informative, and kept me up to date with the progress. I'd recommend Me.Transmission to anyone who would like the save money at the dealer, and get their transmission rebuilt.

Had an excellent experience at this shop. Brought it to my dealership for a suspected transmission problem (shuddering) and they recommended rebuilding it. Came here for a 2nd opinion and they found the problem was actually just a warped brake calliper. I almost bought a new transmission for no reason from my dealership so coming here saved me about $7000. The staff were friendly and great communication at every step. Thanks again for the great work.
