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.

Christy McMurray
Thank you, Mister Transmission! After taking my vehicle to the dealership where I bought it, and paying $150 for them to tell me what I already told them was wrong, the Dealer gave me a quote of $6,500 to replace my 9 year old transmission with a factory rebuilt one, because it couldn't be fixed or rebuilt by them. Thankfully I called Mister Transmission and Chris knew exactly what the issue was, how to fix it, and it only cost me $385 for everything and it was fixed in a day. I am so grateful that Chris and Dawn run an honest operation and provide genuinely great service. Thanks again!

Cambridge Mister Transmission was awesome. We ended up having a small issue but they still took the time to show me where on my vehicle the problems were and fully explain the possible issues. They were prompt in getting back to me the following day and I had my vehicle back in no time. Chris and Nick were amazing and the office is so clean and pleasant. Great customer service!

Chris Elmquist
Mazda 3 AT light came on one with some bad noises and clunking. Dealer said need a new transmission for only $4400. Took it to this and a quick check they determined it needed new TCM which is very common on the mazdas. They took care of it and even did a bunch of extra work fixing a wiring harness all for the cost of the TCM . cannot say enough about how we were treated by Chris and Dawn. Would recommend them. FIRST CLASS!!!!!

Kieran Massicotte
I took my differentials down to get rebuilt and Steve was very professional and the total was 200 bucks cheaper than the quoted price and there was a few things during the whole process that didn’t go as planned as I had brought all the bearings parts and some bearings were the wrong ones and I had brought 4.88s to put in end they would not work and before continuing with anything Steve would call and double check to let you know what needs to be done and get the ok from me first before they would continue overall amazing place Steve and the guys were awesome and the work was done perfect and the diffs have never been more smooth highly recommend.
