What happens when you overheat your transmission?

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.

How do you know if your transmission is overheating?

This article takes a closer look at three common signs 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.

Can you drive with a hot transmission?

In other words, if you hit 220 degrees, you can expect to get about half the normal life out of your transmission. At 240 degrees, your transmission will last about 1/4 the time that it should. And if you get up to 260 degrees, you are down to 1/8 the normal life. Hot transmissions give off an odor.

What temperature is too hot for a 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 temp is too high for transmission?

#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.

Will low transmission fluid cause overheating?

Low levels of transmission fluid will cause overheating because there won’t be enough to go through all of the working parts in the transmission. This will lead to a completely damaged transmission.

How do you stop a transmission from slipping?

Burnt or Worn Out Fluid – Drain & Refill

  1. Jack the vehicle up and unbolt the pan. …
  2. Remove and replace the filter.
  3. Scrape off the old transmission pan gasket and replace.
  4. Bolt-on the pan and fill with ATF.
  5. Start the vehicle and check for leaks.
  6. Use copious amounts of kitty litter to cleanup the mess that you’ve just made.

Can a bad thermostat cause transmission problems?

If the thermostat is stuck open

Temperature gauge reads lower than normal. Heater doesn’t work. Automatic transmission has trouble shifting into higher gears. Fuel economy drops noticeably.

What is normal transmission temp?

Normal transmission fluid temperature is about 160-175 degrees. It might rise as high as 200-220 degrees under demanding conditions but hopefully it won’t go any higher. Transmission fluid degrades rapidly at higher temperatures. Cooked fluid and high operating temperature are transmission killers!
