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.
What temperature is too hot for a transmission?
If the temperature gets above 250 degrees F., rubber seals begin to harden, which leads to leaks and pressure losses. At higher temperatures the transmission begins to slip, which only aggravates overheating even more. Eventually the clutches burn out and the transmission calls it quits.
What is dangerous temp 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.
Is 200 too hot for transmission?
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 know if my transmission is overheating?
3 Symptoms of Transmission Overheating
- Acrid Burning Odor. Transmissions change gears using principles of hydraulic power. …
- Slow Response Times. A transmission stands a much greater chance of overheating if fluid levels drop too low. …
- Transmission Slipping.
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.
What should I do if my 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.
How do I lower my transmission temperature?
Installing an external cooler can prove greatly effective in cooling your transmission and keeping it at a regulated temperature, which helps to prevent damage. External coolers also help to reduce friction to the transmission, which is another common cause of damage.
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.
Does transmission fluid expand when hot?
If the fluid level is OK when cold, it should also be within the cross hatched area for “H” as well. The reason for checking when both hot and cold is transmission fluid expands as it is heated. … Transmission fluid expands and keeps expanding the hotter it gets.
Is 180 too hot for a transmission?
(180°F to 200°F). So, this manual indicates that the normal automatic transmission oil temperature range is 180F – 200F. If you have a temperature gauge on your transmission oil and find that it exceeds those numbers you should be adding an extra transmission oil cooler to your vehicle.
How hot can synthetic transmission fluid get?
Amsoil’s full synthetic ATF is capable of lowering your transmissions operating temperature a full 30-50 degrees and in most cases just a 20 degree drop is more than sufficient.
