What is the max temp for transmission fluid?

The greater the load on the transmission, the more heat it generates and the hotter the fluid becomes. Normally, the maximum allowable temperature for conventional transmission oils is 80 to 100°C/175 to 212°F and for special transmission oils 110 to 130°C/230 to 265°F.

Is 200 degrees hot for a transmission?

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 temperature is too hot for transmission fluid?

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.

What temp should a transmission run?

Normal operating temperature for an automatic transmission is about the same as the engine temperature, i.e., about 195°F. The temperature inside the torque converter, while pulling a big load from a standing start, could easily rise above 350°F.

Can too much transmission fluid cause overheating?

Overheating

Transmission fluid is responsible for keeping the transmission cool. By using too much of it, you could cause an overheating situation, which sounds a little backward at first. However, when you overfill the transmission, there is going to be some leakage from the buildup.

What temp is too hot for 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.

What happens if transmission overheats?

A transmission that frequently overheats can cause fluid to leak from the transmission, so if you are constantly replacing the fluid, it’s a good indication of a leak. A slipping transmission is also an indication of low, dirty, or burnt transmission fluid. You also need to be aware of the check engine light.

What makes a transmission overheat?

An overheating transmission usually means there is already some sort of internal damage or a transmission fluid issue, such as a leak, low fluid level or just old/dirty fluid running through the system. It can also happen with too much transmission fluid, which causes excess pressure within the transmission.

Is 185 to hot for a transmission?

Since automatic transmissions are located closer to the middle of the car, how do you know when your gears are running a little too hot? … A transmission operating temperature normally tends to be anywhere from 175 to 200 degrees, with the fluid inside ranging between 185-194 degrees Fahrenheit.

Is 170 hot for a transmission?

Ideally, the fluid temperature in the automatic transmission would range from 170 to 225 degrees Fahrenheit. If the transmission is slipping or you are pushing the vehicle hard, the temperature could rise above 240 degrees. … The temperature inside the torque converter runs the hottest.

Is 165 a good transmission temp?

At highway speeds, it is usually about 165F.

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. … Shifting problems: When it’s cold, the transmission will shift harder and shift points can become delayed which can lead to yet harder shifting.

How do I lower my transmission temperature?

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.
