According to TCI, the ideal operating temperature for automatic transmission fluid is between 175 and 225 degrees. At approximately 240 degrees, important additives in automatic transmission fluid (ATF) begin to cook. The result is the formation of varnish inside the transmission.
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.
What is the average transmission fluid temperature?
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.
What temp is too high for 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.
Is 180 too hot for a transmission?
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 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.
What is a low transmission temperature?
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.
What temperature is too hot for transmission fluid Celsius?
If the temperature gets above 125 degrees C., 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 makes a transmission hot?
Reasons for overheating include low fluid levels, leaks, burned, old or dirty fluid, or problems with the solenoid. You can ensure the long life and efficient performance of your transmission – and your car – by doing some things to make sure it does not run too hot.
What is normal coolant temperature?
Normal Temperature engine temperature gauge
Most experts agree that your engine should run between 195 degrees and 220 degrees. In ideal situations, your needle will maintain a posture right in the middle of your gauge.
What is normal transmission temperature in Celsius?
A question that gets asked the alot is what is the best temperature my automatic transmission should operate at? Most late model vehicles operate at 90°C – 95°C which is quite normal and what the transmission control module will operate its smoothest shift strategy.
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.
