What is normal automatic transmission temperature?

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. Fluid breakdown often results in harsh shifting and slip-bump concerns.

How hot should a automatic transmission run?

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.

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.

Tips and Tricks to Cool a Transmission

  1. Use an Additive. One of the simplest things you can do to keep your transmission cool and extend its life is to use a transmission fluid additive on a regular basis. …
  2. Go Neutral. …
  3. External Coolers.

How do I check my transmission temperature?

Install the scan tool, start the vehicle and look for the transmission temperature. The fluid temperature should be between the 185- and 194-degree marks with an idle of 600 to 800 rpms. Remove the bolts and clips from the front fender well on the driver’s side, and locate the transmission fill plug; remove it.

How do you know if your transmission is overheating?

Is My Transmission Overheating?

  1. A sudden experience of a burning odor inside and outside the vehicle.
  2. The gears “slipping” when accelerating or decelerating.
  3. A feeling of hesitation or delayed gear shift when you are driving.
  4. Any grinding or shaking sensation that occurs while accelerating or while idling.

What temperature does ATF break down?

As a rule of thumb, every 20 degree increase in operating temperature above 175 degrees F. cuts the life of the fluid in half! At 195 degrees F., for instance, fluid life is reduced to 50,000 miles. At 220 degrees, which is commonly encountered in many transmissions, the fluid is only good for about 25,000 miles.

What causes automatic transmission overheating?

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.

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.

Is 165 a good transmission temp?

At highway speeds, it is usually about 165F.

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 normal coolant temperature?
