Are Transmission Coolers Worth It?

Transmission coolers are absolutely worth it if you plan on towing or doing any kind of heavy-duty hauling. They help reduce the amount of heat built up in your vehicle’s transmission during these activities, which can lead to premature wear and tear. Transmission coolers also help improve fuel economy by keeping the transmission at a cooler temperature, resulting in less strain on the engine and better overall performance.

Additionally, they can extend the life of your vehicle’s transmission by reducing fluid breakdown due to excessive heat build-up. All in all, installing a transmission cooler is an investment that will pay off for years down the road!

How Do I Know If My Transmission Cooler is Working?

To determine if your transmission cooler is working properly, you should check it periodically. You can do this visually by checking the condition of the hoses and looking for any leaks or signs of corrosion on the fittings. Additionally, you can use a thermometer to measure the temperature at each end of the cooler – both before and after fluid passes through it – which will help to identify whether heat is being successfully dissipated from within your transmission’s system.

If there are discrepancies in these readings, then it may be an indication that your transmission’s cooling system needs some attention.

Do External Transmission Coolers Work?

Yes, external transmission coolers do work. They are designed to be installed in the vehicle’s cooling system and act as an additional heat exchanger for the transmission fluid. The cooler helps to reduce the temperature of the fluid, which can extend its life by preventing it from overheating and breaking down prematurely.

Additionally, a cooler allows you to run your vehicle at higher temperatures without fear of damage to the transmission components. In general, they are considered essential upgrades for vehicles that tow or haul heavy loads or are driven in extreme conditions such as off-roading or racing applications.
