Frequent question: At what temperature does synthetic transmission fluid break down?

Does synthetic transmission fluid break down?

While traditional transmission fluid is made from crude oil and the reshaping of hydrocarbons for specifications of different vehicles, synthetic transmission fluid is created through different chemical reactions. This type of transmission oil is less likely to break down, oxidize or thin out in high temperatures.

What temp does transmission fluid degrade?

Without enough transmission fluid or effective fluid, your transmission will start acting out. 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.

How long does it take for transmission fluid to break down?

If you don’t change it often enough, your transmission fluid will become contaminated with metal particles and begin to break down. Transmission fluid change intervals can vary widely, but we recommend somewhere between 30,000-60,000 miles, or every two to four years.

Is 180 degrees 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.

Is it OK to mix synthetic fluid with regular transmission fluid?

Is it OK to mix synthetic ATF with a conventional and/or synthetic blend ATF? Yes. Synthetic ATF and conventional fluids are 100 percent compatible with each other.

How long does full synthetic fluid last?

Transmission fluid does need to be changed from time to time, and the most accurate answer to the question is that the fluid will usually last between 30,000 and 60,000 miles. That said, if your vehicle sustains heavy use, you could have to change the transmission fluid in as few as 15,000 miles.

Is 230 degrees to hot for a transmission?

200-225 is very common when the ambient air temp is 80-100 degrees and your transmission is under an increased load. 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.

Does synthetic fluid run cooler?

With the use of a synthetic product, you will find that your transmission will run cooler and cleaner and will be less susceptible to breakdowns of by-products that can often clog your transmission components or other internal parts.

What temp is too hot 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.

How many miles is synthetic transmission fluid Good For?

Most manufacturers recommend replacing transmission fluid every 30,000 to 60,000 miles. If you tow, or do mostly city driving with constant changes of gears, it may be wise to change your ATF even more often. Here’s why. Your automatic transmission has a lot of moving parts.

Should I change transmission fluid after 100k miles?

Do You Need to Have the Transmission Fluid Changed? The simple answer is yes. But service intervals for new vehicles can exceed 100,000 miles before this needs to be done. … Those who don’t hold on to a new vehicle for very long may never have to have the transmission fluid changed.
