How high is too high for transmission temp

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 temp is too high for transmission?

The ideal maximum transmission temperature is 200 degrees. This is important to know because for every 20 degrees your transmission goes above 200, its life span is cut in half. Think about it. At 220 degrees, your transmission’s life is cut in half.

What is dangerous temp for transmission?

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.

How hot can an automatic transmission get?

Automatic transmission failures are usually a result of overheating. The main culprit for this is low transmission fluid. The normal transmission temp is 175 degrees but with overheating, it could rise to over 240 degrees.

How do you know if your transmission is overheating?

Signs of an Overheating Transmission

If the transmission fluid is dark brown to black in color, it means the fluid is burning from the transmission overheating. Another common sign of an overheating transmission is the smell of burning transmission fluid.

How do I lower my transmission temperature?

Transmission fluid additives contain special coolants designed to reduce the temperature of your transmission, particularly when it is under strain from stop and go traffic, driving on hilly terrain or carrying extra weight. Transmission fluid additives can be purchased at most auto supply stores.

What do I do if my transmission is overheating?

What to do when your transmission is overheating:

  1. Stop driving immediately and let your transmission cool down.
  2. Make a note of what you were doing, where you are, what’s happening (noises, etc.)
  3. After cooling down, start back up & gingerly continue on your way.

Is it OK to slightly overfill transmission fluid?

A slightly overfilled gearbox will not be damaged if quantities such as 0.3 litres/0.3 quarts are involved. If you overfill your transmission with one liter or more above the max mark, your transmission could be damaged. Transmission fluid performs several functions in your vehicle.

How long should I let my transmission cool down?

Pull over, put it in Neutral, and rev the engine (or use your fast idle). About 5 minutes should do it.

What temperature does transmission fluid start to break down?

The ideal fluid temperature is under 175 degrees, but as fluid ages it starts to break down and lose its capacity to cool down the transmission. This is when transmission overheating occurs. At 220 degrees, varnish forms. At 240 degrees, seals start to harden.

Can you over cool a transmission?

Can you over cool the transmission fluid? Answer: Transmissions are not highly sensitive to cool operating temperatures. However, in sub-freezing (20-30°F) weather conditions, transmission fluid can actually gel up in an external cooler and cease to flow, causing damage.

Can too much transmission fluid cause overheating?

The proper amount of fluid also keeps a constant level of pressure inside the transmission. However, when you have too much transmission fluid, the pressure builds within the transmission. … Second, because the gearbox is not fully lubricated, your transmission will start to overheat.

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 are the first signs of a transmission going bad?
