But if the engine coolant level is low, the coolant won’t immerse the transmission cooler properly. So the cooler won’t release the heat necessary for the transmission to cool off. The heat continues to increase in the transmission, causing parts to expand and pressures to build.
Can coolant affect transmission?
It may seem like a rather remote possibility, but engine coolant, or anti-freeze can get into automatic transmission fluid. The temperature of transmission fluid is regulated inside the engine cooling system. … Any rupture of the internal radiator tank can allow coolant to mix with, and contaminate transmission fluid.
Can low coolant cause transmission issues?
Transmission failure – In some cases the transmission fluid cooler is internal to the radiator, meaning that a lack of engine coolant can not only cause the engine to overheat, but also the entire transmission. The engine may overheat and cause even more problems.
What causes high transmission temperature?
It is estimated that close to 90 percent of automatic transmission failures are caused by overheating, and the main reason they overheat is because of overworked transmission fluid. The optimal temperature range for transmission fluid is 175 to 220 degrees.
How do you know if your transmission is overheating?
This article takes a closer look at three common signs of transmission overheating.
- Acrid Burning Odor. Transmissions change gears using principles of hydraulic power. …
- Slow Response Times. A transmission stands a much greater chance of overheating if fluid levels drop too low. …
- Transmission Slipping.
How do you know if your transmission is leaking coolant?
Clues You Have an Antifreeze Leak
- A sweet aroma that you notice from outside the vehicle, coming from the vehicle after you’ve driven it. …
- Puddles under the car of lime-green, orange, pink, or blue-green after you’ve parked. …

How can I make my transmission last longer?
By utilizing the following tips, you can make your vehicle’s automatic transmission last longer.
- Stop Completely Before Changing to Drive or Reverse. Before changing from drive to reverse or vise versa, wait for your vehicle to come to a complete stop. …
- Check Fluid Levels Once a Week. …
- Change the Fluid.
How do I lower my transmission temperature?
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.
What temp should my transmission be when towing?
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.
