Should I bypass my radiator when installing an external transmission cooler?

“Should I bypass a radiator transmission cooler?” No. Automatic transmissions generate a lot of heat — heat that breaks down the fluid that courses through them to make them function. When the fluid breaks down, it can no longer protect the bits that need protecting, so things start wearing and having problems.

What happens if you bypass a transmission cooler?

The thermal bypass is a small added valve that goes in the transmission line. When the transmission is cold, the thermal bypass will “bypass” the cooler so it can bring the transmission up to operating temperature more quickly.

Does coolant run through transmission cooler?

Transmission coolers do not attach to the radiator. They attach in-line with the transmission fluid return line. It is common for an OEM transmission cooler to be built into the radiator tank to be cooled by the coolant in the radiator.

Does a transmission cooler get hot?

160 – 200 are considered normal temps providing your engine radiator is functioning properly . If your engine overheats , your transmission will also overheat when using the factory internal rad cooler . Normal fluid temperature in transmission to be 175 deg.

Does it matter which transmission cooler line goes where?

Generally the higher line on the radiator has fluid going INTO the transmission and the lower one goes back to the transmission, so the higher line has fluid coming out of it and the lower line sucks it back into the transmission.

Does it matter which way you mount a transmission cooler?

Mount the B&M SuperCooler with the fittings on top or on the sides. It is not recommended to mount the cooler with the fittings pointing down as this may create an air pocket in the cooler resulting in reduced cooling efficiency.

Do I need a thermal bypass valve?

A thermal bypass valve is necessary for hydraulic circuits that require fast warm-up, controlled fluid temperature, and low return line backpressure. Temperature control is the critical element for optimal system performance.

Can you install 2 transmission coolers?

Because the Atomic-Cool unit had done so well, another one was ordered up, and the plan was to run both concurrently. The crew at Peformance Transmission in Lawndale, California, were ready to take on the install. This is a relatively simple process; a second transmission cooler can be piggybacked on a primary unit.

Is transmission connected to radiator?

How Car Transmission Lines Work. Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. Also known as transmission cooling lines, they are typically made of metal or composite aluminium and rubber hoses because they can handle the flow of hot transmission fluid.

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 fluid goes through 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.

Are transmission coolers necessary?

For every 20F degree drop in transmission fluid temperature, you can expect to extend the fluid and equipment life, thereby extending the life of the vehicle. That’s why it is very important to have a quality transmission cooler, and more importantly, to have it professionally installed.

Is transmission cooler worth it?

These types of coolers have been around as long as the automatic transmission and for the most part do an effective job of keeping the transmission going for many thousands of miles. The in-the-tank coolers not only perform the job of cooling the fluid, but warm the fluid in extremely cold environments as well.

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.
