Frequent question: What’s the hottest your transmission should get?

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 hot is too hot for transmission temp?

#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 250 too hot for a transmission?

The problem is even normal driving can push fluid temperatures well beyond safe limits. … 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.

How hot can a transmission get?

What if you don’t catch it in time? 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 a normal 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.

Is 210 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.

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 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.

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 synthetic fluid run cooler?

An alternative is to use a high end synthetic lubricant. As a result of the reduced friction, the tranny will run cooler, and transmission life will be lengthened considerably. For example, AMSOIL synthetic automatic transmission fluid provides useful service up twice as long as conventional fluids.

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.

What temp does transmission fluid break down?

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. At 240 degrees, seals start to harden.

What to do when transmission is overheating?

What to do when your transmission is overheating:

  1. Stop driving immediately and let your transmission cool down.
  2. Make a note of what you were doing, where you are, what’s happening (noises, etc.)
  3. After cooling down, start back up & gingerly continue on your way.
