Quick Answer: How do you keep a transmission cooler?

How do I stop my transmission from getting hot?

A transmission cooler provides extra cooling power to your car’s cooling system, assisting it in preventing the many hot, running systems in the engine from overheating. The best transmission cooler is a stack plate cooler.

How does a transmission get cooled?

In almost all vehicles with an automatic transmission there is a transmission cooler placed inside the radiator. Most standard transmissions do not make as much heat and therefore do not have a cooler. … This way the transmission is being cooled by two different coolers; one with antifreeze and on through air flow.

Does a transmission cooler really help?

An automatic transmission works harder when towing heavy loads or driving in rough conditions, so it gets hotter than usual. … A transmission cooler helps the transmission stay cool, even when working harder than normal, which in turn lets you get the best performance and long life out of it.

What temperature is too hot for transmission fluid?

Fluid Life Expectancy vs Temperature

The ideal operating temperature of transmission fluid is 175 degrees. Overheating occurs after the temperature surpasses 200 degrees, and the failure rate doubles for every additional 20 degree increase after that.

What makes a transmission overheat?

Low fluid levels or old transmission fluid causes friction between the parts and causes overheating. Fluid problems are the most common reason for transmissions overheating.

How do I keep my transmission cool while towing?

Adding a simple auxiliary cooler inline with the factory unit can nearly double the life of transmission fluid, keeping your gearbox happy and healthy for a long time. Also helpful are aftermarket aluminum pans. Their added fluid capacity and finned heat-sink design provide additional cooling as well.

Should transmission cooler be before or after radiator?

Should the cooler be installed before or after the radiator? Answer: We recommend installing the auxiliary cooler after the radiator to return the coolest fluid directly to the transmission.

Can you drive without a transmission cooler?

Yes, I said “almost” because some cars have an air-cooled transmission. A perfect example of this is the Chevrolet Corvair Powerglide transmission, in the ’60s. It had cooling fins. Otherwise, without a cooler, the transmission will overheat.

Do transmission coolers need a fan?

Mechanical fans are almost always better than electric fans in terms of CFM or cooling power if you will. In this case an external transmission cooler is what is needed. Whether it needs it’s own fan or not would require testing the temps of the fluid to find out.

Is a bigger transmission cooler better?

The larger the cooler, the better it will be at lowering fluid temperature. The plate and fin and the stacked plate coolers offer a larger surface area to cool transmission fluid faster and better, which is why they are so popular.

How do I know if I need a transmission cooler?

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.

What fluid runs through a transmission cooler?

A transmission cooler operates like a heat exchanger mounted adjacent to your car’s radiator. Hot transmission fluid flows through the unit and comes in contact with a series of fins or plates.
