Do I Need a Transmission Cooler?

By Mister Transmission

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.

I had an issue with...
Scott J
I had an issue with my Nissan Altima jerking on the way home. Waited into I could take it here and have them do a quick test drive (which is free and very nice, though they may not feel the same issue which is the hard part). Peter was able to tell something was wrong and it’s a common issue with the CVT transmission on Nissans. He took us in the back of the shop as they were currently working on one and could show us the pulleys and CVT housing and the one piece that fails. Unfortunately, due to the price of the parts from Nissan, and low margins, and the fact that in order to fix the one small part would require a whole new transmission to ensure everything was new, it would be $4,500-5,500 + taxes. This is basically the value of the car (probably more than the worth) so not really an option for us. We appreciated the detailed info and seeing the parts and the free test drive. Very helpful - so if you have an issue with your transmission and know nothing about cars (like me), definitely worth it to take here.

William Ong
My son’s Pontiac Vibe was developing a whiny noise. We traced the sound to the front of the engine. We brought the car to Mister Transmission for them to diagnose. They took time to fully check it out and found the ac compressor to be the culprit. They didn’t charge us at all. I can’t thank them enough. They gave recommendation on what to do. Good people.

Akayla Mitchell
I don’t even know where to begin. Mark went above and beyond from our first conversation and walked me through everything and kept me updated the whole way. My car ended up being more complex then we all originally thought but the team handled it amazingly and Mark made sure I understood everything that was happening and worked longer hours to help trouble shoot. I must say have to worry about a big repair on a 3 month old car was not something I imagined having to navigate but Mark showed compassion and honesty I would go back in a heartbeat(hopefully I won’t need to for a long time!) Thank you again Mark, Tyler and team. My car runs 1000x better than when I bought it.
