Do you have to bleed transmission cooler?

You would not need to bleed the transmission cooler part # D13503 before you install it on your truck. The fluid is thick enough and the pressure it high enough that air bubbles would immediately work themselves out.

What to do if your transmission cooler is bad?

The only way to fix a bad transmission cooler or line is to replace it. Since the factory transmission cooler is typically found within the radiator, this means the whole radiator will have to be replaced as well. If this is the case, it is highly recommended to perform a full coolant flush to ensure no ATF got into the cars cooling system.

Is it better to bypass the factory transmission cooler?

If you live in a very warm area, it may be better to bypass the factory transmission cooler in the radiator in favor of a larger, external transmission cooler.

Where does the coolant go in a transmission cooler?

To cool the fluid, it travels through the transmission cooler, where it can be dispersed with the help of the radiator and coolant before returning back to the transmission. If you have a transmission cooler located on the air conditioning condenser, the fluid is cooled with the help of this system instead.

Why do you need a transmission cooling system?

When you install your cooler you will need to account for adding additional transmission fluid to compensate for the increased capacity of the transmission cooling system. A transmission cooler will not only help keep your fluid temperatures lower, but improves the longevity of your transmission.

Where does transmission fluid go in an aftermarket transmission cooler?

When an aftermarket transmission cooler is installed, you can plumb it a number of ways.

Why do you need a radiator cooler on a transmission?

now also add the extra B&M aux cooler, but do not just bypass the radiator. The radiator cooler serves two functions. It warms the trans fluid to operating temp quicker than the transmission can do on its own, which help prolong its life.

Why do I hear grinding in my transmission cooler?

You might hear grinding during a shift change or clunking. The entire purpose of the transmission cooler is to reduce the heat in the fluid as it passes through the system. When the cooler can’t work right, it leads to higher fluid temperatures. When the transmission becomes too hot, other problems follow.
