How does an automatic transmission cooler work?

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. The resulting heat dissipation cools the liquid as it cycles back into the transmission.

How does an automatic 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.

Why is an oil cooler necessary for an automatic transmission?

Do I Need a Transmission Cooler? Transmission coolers help to protect your transmission when you turn up the heat. Transmission Coolers help transmissions deal with the added stress and heat caused by towing boats, trailers and other heavy objects.

How do I know if my transmission cooler is working?

You hear odd noises coming from the transmission: Your transmission may have difficulty shifting between gears, or there may be clunking or grinding noises during shifts. This can indicate transmission fluid loss, high internal transmission temperatures, or both, which can be caused by a bad transmission cooler.

Is a transmission cooler a good idea?

It is a flow-through device and does not affect any internal components of the transmission. A transmission cooler will just help to prolong the life of the transmission by keeping the fluid cooler. Transmission fluid cannot be cooled too much, so the addition of a cooler is a good idea, especially if you are towing.

Can an automatic transmission run too cold?

The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick. The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily.

Does the radiator cool the engine in the transmission?

When the fluid passes through a small tank inside the engine’s radiator it cools the engine. … All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.

Does transmission cooler increase performance?

Though each performs the same job – cool the transmission – each type does it a little differently. Whichever transmission cooler design you choose, rest assured that it will extend the life of your transmission by preventing heat-related failures and improving shifting performance.

Is a transmission cooler the same as an oil cooler?

Transmission, differential, and power steering coolers do the same thing an engine oil cooler does. They transfer heat away from the lubricating oil. Although it may seem like transmissions, differentials, and power steering run cooler than engines, exactly the opposite is true.

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.

What happens when transmission cooler line breaks?

Like all parts of an engine, transmission cooling lines can wear out. If they break or develop a leak, you will lose transmission fluid, leaving your car vulnerable.

Should transmission cooler be before or after radiator?

Answer: We recommend installing the auxiliary cooler after the radiator to return the coolest fluid directly to the transmission. Installing the cooler before the radiator will still provide additional cooling and may be necessary in some difficult-to-access applications.

How big of a transmission cooler do I need?

You should get the biggest heavy duty transmission cooler that can fit on your car! 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.

Where do you put a transmission cooler?

The cooler should be mounted ½ to 1 inch in front of the radiator or A/C condenser for vehicles with air conditioning.

  • Find the oil cooler lines. …
  • With the mounting hardware provided with your oil cooler kit, mount the cooler 1/2 to 1 inch in front of the radiator or A/C condenser.
