Is it safe to bypass radiator transmission cooler?

Bypassing your radiator transmission cooler would likely cause the fluid in your transmission to over heat causing premature transmission failure.

Can I bypass my transmission oil cooler?

When the transmission is cold, the thermal bypass will “bypass” the cooler so it can bring the transmission up to operating temperature more quickly. … The bypass works very well with other coolers, such as the Tru Cool™ 49211 cooler. So if you already have a cooler you like, adding the bypass on is definitely okay.

Is a transmission cooler necessary?

Our coolers offer maximum heat dissipation by constantly swirling and agitating the fluid as it flows through, and with the addition of our thermostatic flow control we ensure that your customer’s transmission maintains the ideal temperature for shiftability and long-life.

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.

What happens if you bypass transmission cooler?

Bypassing your radiator transmission cooler would likely cause the fluid in your transmission to over heat causing premature transmission failure.

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 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.

Can a transmission run too cool?

Heat is a huge cause of transmission failures but running too cool is bad also. Just as an engine has to run hot enough the trans has to run hot enough to get rid of any condensation that builds up inside and to keep the viscosity at the correct level for best operation.

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.

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

What fluid runs through transmission cooler lines?

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.

What fluid runs through a 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 transmission bypass?

The thermal bypass valve is the gatekeeper of cooling your transmission, quite literally. Depending on the vehicle, ATF will cycle out through an external cooler once it reaches a specified temperature. Once that heat builds, an internal thermostat shifts and opens a passageway to the cooler.

What is a transmission cooler bypass valve?

INTRODUCTION. The thermal bypass valve is used in transmission cooling & heating systems. It regulates oil flow and flow direction in order to self-control the operating temperature of the transmission. … In hot weather the valve allows oil to flow to the vehicle auxiliary oil cooler for maximum cooling performance.

Is radiator connected to transmission?

The largest component to your vehicle’s cooling system is the radiator, but did you know that the radiator is also connected to your transmission and in some cases your engine’s oiling system too? Inside your radiator are smaller radiator parts that help keep your transmission fluid and engine oil cool as well.
