Question: What is a safe transmission 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.

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 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.

How do I lower my transmission temperature?

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.

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.

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.

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 I know if my 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?

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.

What should I do if my 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.

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.

What is a good coolant temp?

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.

Why do CVT transmissions overheat?

#2: Overheating CVT

The belt-driven CVT transmission is cooled by transmission fluid. If there’s been a fluid leak, a glitch in the computer or some other problem, the transmission could begin to overheat. … You may be low on transmission fluid, or the fluid you already have may need to be exchanged for fresh fluid.
