Do You Need a Transmission Cooler?

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.

These days, among all the horror stories you hear about auto shops who either don't know what they're doing or flat out make things worse (and charge mightily either way), it's easy to overlook the real gems who deliver over and above. This shop came highly recommended to me by my son's auto shop class teacher - this on top of the numerous and overall excellent Google reviews. I had transmission shifting problems with an old Dodge pickup truck with which they were initially unfamiliar, and not only did they take on the challenge, research possible causes, and effect what appeared to be logical repairs (at a *very* reasonable price, I might add), when those repairs turned out not to be the root cause of the problem they took it upon themselves to further track down and fix the problem without additional charge (drawing upon their networks of other contacts in the industry to do so). All in a timely manner, keeping well-appraised of their progress every step of the way. As a small business owner myself, I can say that you simply can not expect better service than this. If I could give more than 5 stars I would. Although this is my first experience with them, I will not go anywhere else in the future for transmission work on any vehicle I own.

Mister Transmission saved us! We had a sudden car issue and were taken care of by Raman. He quickly let us know how to get our vehicle to the shop and was very transparent about the process. He was up front with all costs beforehand and was very responsive, putting us immediately at ease. The fix was completed quickly and even before the estimated time given! We were super pleased with his professionalism, knowledge and workmanship. Car issues suck, but this was an excellent, pain free, no hassle, process. Highly recommend!Thank you Raman & Mister Transmission team!

The owner went above and beyond to fix my car. So much so he called one of his employees back after they were closed to check another issue for me that was unrelated to my original issue. Amazing is all I can say

Paul was the gentleman who was taking care of my appointment. He was very informative with the issues I was having with my transmission. He was honest in giving his opinion on what course of repair I should use to fix my issue. His customer service and personability were exemplar. The repair was done in a timely manner and he even did some cleaning of the engine bay of my car without mentioning it. For any transmission or drive system repairs I wouldn't recommend any shop other than this one.

Do not hesitate to get Mr. Transmission to take a look at your vehicle. They will properly diagnose and fix your issues, with no hidden nonsense. Very straight shooters. Cam was great to deal with. They completely rebuilt my transmission, and I ran into a small issue later on. They took care of my issue under warranty, and it didn’t cost me a penny. Fantastic mechanics and customer service! We will be returning for any vehicle needs in the future.
