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.
Is 200 degrees hot for a transmission?
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. … Hot transmissions give off an odor.
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.
How do I cool down my transmission?
Allowing the car to idle in neutral, while sitting at red lights, in congested traffic or at rail road tracks, reduces the strain on the transmission, allowing the transmission to cool.
At what temp 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 temp high?
Old, worn out, or burned fluid will cause the transmission to run hot. Transmission slipping is another hint that the fluid is low and old. A defective solenoid can cause the transmission to run hot. Driving habits, conditions, and weather are other possible causes of transmission overheating.
How do I know if my 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.
What to do when 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.
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.
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 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 does it mean when your transmission fluid smells burnt?
Overheated or low transmission fluid could be a potential source of this burning smell. Fresh transmission fluid tends to smell sweet or tart. When that smell turns burnt, your transmission fluid has broken down and the system is burning too hot, leading to an increase in friction and corrosive activity in the engine.
