The ideal temperature for your transmission is 200 degrees. For every 20 degrees past 200, the lifespan of your transmission is reduced by a factor of 2. In other words, if you hit 220 degrees, you can expect to get about half the normal life out of your transmission.
How hot should a automatic transmission run?
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?
#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.
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.
Can transmission temp be too low?
The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick. The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily. … If water is in it when cold, it will freeze at 32 degrees Fahrenheit.
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 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 to do when your transmission is overheating?
What to do when your transmission is overheating:
- Stop driving immediately and let your transmission cool down.
- Make a note of what you were doing, where you are, what’s happening (noises, etc.)
- After cooling down, start back up & gingerly continue on your way.
What temperature is too cold for transmission fluid?
The ideal temperature for your transmission fluid is 175 degrees, plus or minus 25 degrees, however, when your transmission gets below zero degrees, it gets too thick. In this condition, it won’t be able to properly lubricate the internal parts, wearing the transmissions internal parts.
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.

Can a bad thermostat cause transmission problems?
If the thermostat is stuck open
Temperature gauge reads lower than normal. Heater doesn’t work. Automatic transmission has trouble shifting into higher gears. Fuel economy drops noticeably.
What is the normal temperature of transmission fluid?
It doesn’t take long for the automatic transmission fluid (ATF) to heat up once the vehicle is in motion. Normal driving will raise fluid temperatures to 175 degrees F., which is the usual temperature range at which most fluids are designed to operate.
What temperature does transmission fluid boil?
The boiling point of tranny fluid is much, much higher than 200 degrees F. Your transmission fluid would have to get to about 600 degrees F. before it would boil. Auto Transmission Fluid (ATF) – This fluid is a highly specialized oil optimized for the special requirements of the automatic transmission.
Why is my transmission fluid cold?
If the fluid level was below the “Cold” range on the dipstick when the engine is cold, then you need to add more transmission fluid to the transmission. If the fluid level was below the “Hot” range on the dipstick when the engine is hot, then you need to add more transmission fluid to the transmission.
