You asked: What temperature should your transmission run?

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?

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. Eventually the clutches burn out and the transmission calls it quits.

What is a safe temperature 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.

When should I worry about my transmission temperature?

By the time the temperatures reach 250 degrees, the rubber seals have started cracking and leaking pressure and liquid. At over 290 degrees, the transmission will often have stopped working due to damaged parts and seals.

How do I lower my transmission temperature?

External Coolers

Installing an external cooler can prove greatly effective in cooling your transmission and keeping it at a regulated temperature, which helps to prevent damage. External coolers also help to reduce friction to the transmission, which is another common cause of damage.

How do I know if my transmission is overheating?

3 Symptoms of Transmission Overheating

  1. Acrid Burning Odor. Transmissions change gears using principles of hydraulic power. …
  2. Slow Response Times. A transmission stands a much greater chance of overheating if fluid levels drop too low. …
  3. Transmission Slipping.

What is to hot for a transmission?

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.

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.

Can a transmission be too cold?

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. The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily. … If water is in it when cold, it will freeze at 32 degrees Fahrenheit.

What do you do when your transmission temperature light comes on?

If you see this red light come on in your car, you should first pull over to allow your transmission to cool. If not, you could cause expensive transmission damage. Then, as soon as you can, bring your car in to have it serviced immediately.
