Do You Need a Transmission Cooler?

September 30, 2019 | By Mister Transmission

Do You Need a Transmission Cooler?

Overheating is like kryptonite for your transmission. Transmissions work best when they can stay cool. (“Cool”, not cold. In winter, transmissions can take time to warm up.) But the engine block gets hot and this can heat the transmission. Furthermore, there are transmission problems that can interrupt your transmission’s normal cooling mechanisms and cause it to overheat. All of this begs the question: do you need a transmission cooler?

Transmission Temperature

Transmission fluid is tasked with regulating your transmission’s temperature as well as lubricating parts of it. The healthy range of temperature for transmission fluid is about 71 to 93 degrees Celsius. If your transmission fluid exceeds this temperature, it will begin to burn. This is bad. Not only can burnt fluid not effectively cool your transmission, it can actively damage it, even after is has cooled down.

Clearly, overheating your transmission and thus your transmission fluid is something to be avoided. But how can you avoid it? Well, most transmissions when operating under normal conditions will not exceed this range, even on long drives. But a malfunctioning transmission? There’s no telling. This is why you must get your transmission inspected at the first sight of trouble. Don’t let leaks, whirring noises, or grinding go ignored. Bring your vehicle into a Mister Transmission repair shop as soon as you notice any problems. Furthermore, don’t put any undue stress on your transmission. Drive responsibly and easy.

Transmission Coolers

If you drive a truck or other form of vehicle for work that involves towing, then you’re in danger of overheating your transmission. Just like walking back from the grocery store with all your shopping will make you hot and sweaty on an otherwise temperate day, towing heavy loads will overheat your transmission. Likewise, if you’re planning on a long road trip with a lot of stuff in your car, you could also be at risk of overheating your transmission.

In such instances as described above, you should consider installing a transmission cooler. A transmission cooler is a component that you can add on to your transmission that, big shock here, cools your transmission. It does so by cooling heated fluid that is sent through it by using the air flowing over the fins of the cooler. The cooled liquid is then sent back to the transmission in a continuous loop.

Installing Transmission Coolers

Transmission coolers are not standard issue. There are different types and sizes of transmission coolers for different types of transmissions and different sizes of vehicle. Your vehicle’s gross vehicle weight rating (GVWR) is key to determining what kind of transmission cooler you need. As is the type of terrain over which you usually drive. Hilly and rocky terrain might require more of a heavy-duty transmission cooler.

The choice of where to install your transmission cooler is also tricky. You could put it just about anywhere you find space. But airflow is key; you want to install it where it will experience the most airflow and thus be the most effective.

Great experience. They didn’t charge me for diagnostics- other mechanic shops I’ve been to in red deer will charge around $150 so simply scan your vehicle so that was very positive. Good guys, would recommend

I had an outstanding experience here. From start to finish, the team was professional, friendly, and incredibly knowledgeable. They quickly diagnosed an issue with my truck and offered a clear, honest explanation of what needed to be done. The repair was completed efficiently, and the price was very fair. I also appreciated their transparency throughout the process and how they kept me updated on the progress. It's rare to find such trustworthy mechanics, and I’ll definitely be returning for all my future car needs. Highly recommend!

I had an excellent experience with Giorgio! He took the time to explain some issues with my car's transmission and motor mounts. He went above and beyond to help me—without charging me a dime. His honesty, knowledge, and willingness to assist were truly impressive. It’s rare to find someone so dedicated and kind in the automotive industry. I highly recommend him to anyone in need of expert advice and great service.

Alexander Sousa
Customer service was exceptional, especially the free diagnosis. Alistair was excellent and very knowledgeable at explaining my transmission issue in detail and providing a breakdown of the problem for my vehicle in specific. Transmissions are an unfortunate expensive repair, but I was pleased with the results and my vehicle’s improved performance. My vehicle ended up being a two day fix. I highly recommend visiting Mister Transmission in Burlington instead of taking your vehicle to a dealership that will double the cost of a minor repair, just to have thicker pocket change.

I found myself on a road trip with a low rear Differential oil level. I stopped in and asked if they could take a look before heading home. Not only did they get me in between other work and fill the differential but didn't even charge me for there help. That's old time service Thank you. I will repay this kindness to someone in need.

Acouple years ago CAA was a pick and wouldn't tow my POS car to my apartment and I was strapped for cash so I asked them to drop my car in this guy's parking lot so I could push it to my place... he came out after hours and asked what I was doing... he was very cool about me dropping my car there. Glad to see he has a near perfect rating, others get way to involved.
