Best Transmission Coolers – Reviews & Buyer’s Guide

best transmission coolers - top rated transmission coolers - Transmission Cooler Guide

Transmission coolers have one job, keeping your car’s transmission fluid cool. The cooler is used every time your car is running. If you’re wondering if an external transmission cooler is worth it, that is for you to decide. More often than not, transmission oil coolers are a worthwhile investment to help prolong the life of your transmission.

A transmission cooler is needed if your vehicle requires extra transmission cooling such as towing heavy loads, live in a warm climate area, or often drive in stop and go traffic, you may want to consider getting a transmission cooler. These types of driving conditions will increase the risk of your transmission overheating, which can cause premature transmission failure. 

Once your transmission fluid reaches a certain temperature, the internal components within the transmission will begin to fail and not be able to do their job, which is to move your vehicle. Below is a transmission temperature chart showing the ideal temperatures for transmission fluid, and the lifespan you can expect out of your transmission at certain temperatures. 

transmission temperature chart - Transmission Cooler Guide

If you are unfamiliar with what a transmission coolers is or how they work, here is a quick rundown of the different  types of transmission coolers available and the way they function:

Tube and fin coolers have a characteristic tube winding through it. The tubes encased within turbulators carry the fluid while the fins on the outside absorb the heat from the fluid.

Plate and fin coolers, unlike tube and fin coolers, plate and fin coolers have parallel plates running horizontally. You might confuse it for a radiator at first glance. With a larger surface area, fluid passes through the row of plates for more effective cooling.

Stacked plate coolers are arguably the most popular and have the best cooling efficiency out of the three types of coolers. This cooler has stacked plates (like its name indicates)  that make it look like a radiator. Similarly, fluid is forced through cooling plates to cool it. However, they have larger turbulators for higher air flow.  

How Much Do Transmission Coolers Cost?

Transmission cooler costs can vary depending on the size and style.  Often the bigger the cooler, the more it will cost.  Typically tube and fin coolers are the least expensive, followed by plate and fin, then stacked plate being the most expensive. 

It is likely that a transmission cooler for your every day vehicle may cost somewhere in the $40 – $80 range.  A transmission cooler in this price range will be able to handle all of your daily driving needs. 

If you need something more heavy duty for towing or drag racing, you can expect to spend anywhere from $50 to over $200.  Coolers in this price range offer much more cooling capacity, and are better suited to handle the more extreme conditions to help keep your transmission temperatures in a safe range.

Let’s take a look at some of the best transmission coolers available.

Transmission Cooler Buying Tips

When it comes to purchasing a transmission cooler for your car, truck, or SUV, it is important to understand your needs, and how much cooling capacity you need. In addition, below are some other factors that need to be taken into account as well.

Efficiency – this is the obvious thing to look into when buying a transmission cooler. Assessing a transmission cooler by your vehicle’s needs and the cooler’s capacity are important factors.  If you have a simple car you use to get to work everyday, a basic tube and fin cooler may be best. However, if you have a truck that tows often, a large stacked plate cooler might be more up your alley.  

Compatibility – purchase a cooler that is compatible with your automobile. I’m not talking about how it aligns; this is important too. A compatible cooler should suit the cooling requirement of your vehicle.

Ease of installation – If you are looking to install a transmission cooler yourself, it is best to get one that won’t be too complicated.  If this is your first time installing a transmission cooler, it is recommended to get one that comes as a complete kit.

Reviews – before you click that final buy button, you may want to go through the reviews section. Reviews give you a generally unbiased outlook on the functionality of the cooler. The specs may look great on paper but how well does the cooler actually perform?

Final Thoughts

Choosing a transmission cooler is a delicate balance of a number of factors. Before you can settle on one choice, make sure to evaluate all of your options, and see which cooler would be best based on your vehicle specs and cooling requirements.

If you want, you can make a comparative checklist and see which transmission oil cooler suits you best. If you think your vehicle’s transmission temperatures are too high, or you are looking to add a cooler for extra insurance, be sure to choose a cooler that’s best for your application. It is important to understand what your transmission needs and select the best transmission cooler to help solve these needs for a well performing long lasting transmission.
