What fluid is in 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. The resulting heat dissipation cools the liquid as it cycles back into the transmission.

What fluid runs through transmission cooler?

Transmission oil can reach extremely high temperatures during operation, and this fluid can be cooled down with an external oil radiator. Some vehicles manufactured after 1975 will have transmission coolers built into the car’s radiator, as will most trucks designed for towing.

What is inside a transmission cooler?

The tube-and-fin type consists of a tube that carries transmission fluid through the cooling unit. … The heat is absorbed by the aluminum and is transferred to aluminum fins attached to the outside of the tube, which quickly dissipates the heat.

Does a transmission cooler need fluid?

A transmission cooler is a component that you can add on to your transmission that, big shock here, cools your transmission. It does so by cooling heated fluid that is sent through it by using the air flowing over the fins of the cooler. The cooled liquid is then sent back to the transmission in a continuous loop.

Does coolant run through transmission cooler?

The transmission cooler lines are piped to the radiator and run through an internal circuit that’s kept separated from the coolant.

Can I use rubber hose for transmission cooling lines?

You can use rubber hose, but make sure it’s transmission cooler line rated. The pressure is quite low (12-15 psi). Double clamp it or use FI type clamps instead of the worm-drive style.

Does transmission fluid flow through radiator?

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.

What does oil cooler do?

An oil cooler is a radiator-like component specifically designed to keep your oil cool. It consists of tubes and fins that allow for good airflow to pass through. Usually, they are placed where they can receive maximum airflow such as in front of or behind the radiator or fans.

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.

Is transmission cooler worth it?

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 transmission fluid mix with oil?

When different types of oils and greases are mixed together, it can spell disaster for machinery. This is why it’s best to avoid mixing lubricants. … For example, if you mixed 1 gallon of automatic transmission fluid (ATF) with 300 gallons of gear oil from the same mineral group, the dilution would hardly be noticeable.
