Transmission Cooler Information

Transmission Fluid Temperature

Transmission coolers have one job, keeping your car’s transmission fluid cool.  ATF flows through this cooler every time your car is running. All automatic transmission equipped vehicles come with a transmission cooler built into the radiator.  This cooler allows the fluid to warm up to a suitable temperature. 

The draw back to this is that the factor cooler inside the radiator does not do a good enough job at cooling because it is surrounded by hot coolant. One way to combat this is to use an externally mounted cooler in conjunction with the factory unit. This will allow the trans fluid to heat up first then pass through the external cooler before flowing back to the transmission.

A transmission oil 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 installing an aftermarket 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 Cooler Types 

If you are unfamiliar with what a transmission oil 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 body of the cooler allow the fluid to flow freely while the fins on the outside absorb the heat.

types of transmission coolers - transmission cooler guidePlate and fin coolers, unlike tube and fin coolers, plate and fin coolers have parallel plates running horizontally throughout the body of the cooler, similar to that of a radiator. With a larger surface area, transmission fluid passes through the row of plates for more effective cooling compared to tube and fin coolers.

plate fin transmission cooler - Transmission Cooler Guide 

Stacked plate coolers are arguably the most popular type of transmission oil coolers and have the best cooling efficiency. This cooler has stacked plates (like its name indicates)  that also make it look like a radiator. Similarly, fluid is forced through cooling plates to lower temperatures. 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 type.  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 tranny cooler for your every day vehicle may cost somewhere in the $30 – $80 range.  A transmission cooler in this price range will be able to handle all of your daily driving needs. 

If you are looking for a more heavy duty transmission cooler for towing or drag racing applications for example, you can expect to spend anywhere from $50 to over $200.  Coolers in this price range are typically larger in size offer much more cooling capacity, have a higher GVWR, and are better suited to handle the more extreme conditions. Based on the needs these more higher volume trans coolers will help keep your transmission temperatures in a safe range.

Best Transmission Coolers Brands 

Shopping for a transmission cooler for your car, truck, or SUV can be a challenge if you are unfamiliar with this product.  However, once you figure out your needs, there are a number of companies out there that provide reliable transmission cooling.  

Some of the top transmission cooler brands include:

Each atf cooler brand has its own styles that offer maximum cooling for you vehicle.  No matter what cooler you need, any of these brands can keep your transmission temperatures where you need them to be.

Tru Cool Transmission Coolers

Tru Cool Transmission Coolers - Transmission Cooler Guide

Tru-Cool has a long standing history of developing some of the most quality transmission coolers available.  Their motto is “Drive Hard. Rest Easy”. The engineering behind Tru-Cool’s line of coolers allows for more efficient cooling, even when fluid is still cold. 

Tru-Cool offers two main styles of transmission coolers, their Max and LPD. The Tru-Cool Max coolers are designed for vehicles that require heavy duty use and need a cooler that can handle the abuse.   These coolers are some of the most popular in performance trucks or for towing, more specifically the Tru-Cool 40k because of its 40,000 GVWR

Tru-Cool Low Pressure Drop (LPD) Transmission Coolers

The Tru-Cool LPD coolers are built with a low pressure drop system similar to B&M. These coolers have 13 sizes to choose from in either stacked plate or tube and fin designs depending on your needs.   Tru-Cool claims their low pressure drop coolers provide 30% more cooling than tube and fin coolers. 

The low pressure drop system works based on the coolers having a unique cold weather passive bypass that allows thicker automatic transmission fluid (ATF) to flow more efficiently through the cooler at the top of the system, or as it enters the cooler. As ATF temps increase and becomes thinner, the warmer fluid will start to flow more freely through the body of the cooler. Essentially, this system is self regulating for maximum cooling efficiency and protection. The below image shows how the Tru-Cool LPD system in their coolers works.

Transmission Cooler Buying Tips

When it comes to purchasing a tranny 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.
