Save Money With An Aftermarket Transmission Cooler On Your Vehicle

Has anyone ever told you to install an aftermarket transmission cooler on your vehicle? Do you know why they gave you that advice? Did you do it? Let’s discuss why aftermarket transmission coolers are so important and how they can actually save you money!
There is one reason and one reason only to install an aftermarket cooler on your automatic transmission equipped car: to keep the transmission from overheating. Overheating is the number one cause of premature automatic transmission failure. If you can prevent your transmission from overheating you will delay the purchase of a new transmission by a considerable amount of time.
We’ve discussed this fact in other articles, but I will mention it again. For every 20 degrees you go over the temperature of 200 degrees you cut the life span of the transmission by a factor of 2. To put it in easier to understand terms, at 220 degree the life is cut in half. At 240 degrees the life span is cut to a quarter, and at 260 to 1/8th.
So you may ask yourself why don’t the automotive manufacturers install a better cooler on their vehicles right from the factory? First, they add extra cost to the vehicle. Bean counters are looking to save every penny possible. Automobile manufacturers use the most cost effective parts in order to maximize profit. The automotive parts industry has been guilty of price fixing. What this means is that auto parts manufacturers have agreed to set prices in order to control supply and demand. Companies that manufacture vehicles must purchase parts from these companies, and they pass the added cost on to the consumer.
Second, we sometimes use our vehicles in a way they were not designed to be used. Hard off-roading, racing, towing above recommended weight limits are all ways we abuse our vehicles.
Transmission coolers come in many sizes, shapes and designs. There are coolers that are made of tubing and have thin cooling fins brazed to them. These coolers are cost effective but not super durable. There are coolers that use a stacked plate design. These coolers are more costly but are much more durable and are actually more efficient than the tube type coolers.
A transmission cooler is only efficient if it gets adequate air flow. The airflow is what helps move the heat from the cooler to the surrounding air. Therefor it is import to mount the cooler in such a way that it gets airflow while going down the road. Today’s modern cars are compact and space under the hood is at a premium. Not to worry. Coolers with built in fans are available from a number of manufacturers. With a built in fan the transmission cooler can be mounted almost anywhere, even under the vehicle. The best transmission cooler with built in fans will also come with a temperature controller that turns on the fan only when needed. Most are designed to turn on at 160 degree.
Don’t just sit there reading this article. Go out and get a cooler for your automatic transmission equipped vehicle now and save yourself the cost of replacing your transmission prematurely!
