Frequent question: How do I keep my transmission cooler?

How do I stop my transmission from getting hot?

A transmission cooler provides extra cooling power to your car’s cooling system, assisting it in preventing the many hot, running systems in the engine from overheating. The best transmission cooler is a stack plate cooler.

Where is the best place to put a transmission cooler?

Mounting a transmission cooler is typically best in front of the air conditioning condenser so it gets ample air flow. Mounting here provides significant air flow which will help keep temperatures low. In addition, having the right parts to install a transmission makes the process easier.

What causes high transmission temperature?

Temperatures begin to increase when your transmission of lubricating fluid is scarce. This breaks down the liquid within your transmission, generating even more friction, but instead of forgiving your palms, bits of metal scrap together, seals break, and many components approach destruction.

Does coolant cool the transmission?

The cooler for the automatic transmissions are placed inside the radiator, the reason behind this is the antifreeze provides the perfect environment. It warms the transmission up with it’s cold and keeps it from getting too hot in extreme heat.

How hot is too hot for a transmission?

Fluid Life Expectancy vs Temperature

The ideal operating temperature of transmission fluid is 175 degrees. Overheating occurs after the temperature surpasses 200 degrees, and the failure rate doubles for every additional 20 degree increase after that.

What happens if your transmission gets too hot?

#1 Cause of Failure

The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, 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.

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.

Do you really need a transmission cooler?

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.

Why does my transmission stop working when hot?

Transmissions shifts hard when hot because their parts tend to get damaged, worn, and malfunction under high heat levels. Your transmission needs fluid to keep cool and if the fluid leaks then it may create more heat and pressure.

IT\'S FUNNING:  Quick Answer: What is the average cost for a transmission flush?

Does ATF expand when hot?

The reason for checking when both hot and cold is transmission fluid expands as it is heated. … So, when checking if it’s hot, you can’t do that check if you just drove 50 miles across the desert because the fluid will have expanded. Transmission fluid expands and keeps expanding the hotter it gets.

What is too hot for an Allison transmission?

Temperatures from 230-240 have been reached with no damage to the transmission. If you are seeing temps above 225 degrees on a regular basis you should check your fluid level. Fluid levels to high may cause excessive temperature. … These transmissions will run from 200-230 in the summer months when towing in hilly areas.
