What transmission temperature is too hot?

What transmission temperature is too hot?

#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.

What should the transmission temp be when overheating?

The main culprit for this is low transmission fluid. The normal transmission temp is 175 degrees but with overheating, it could rise to over 240 degrees. This then leads to hardening of seals, and they soon start to melt slowly.

What happens when transmission fluid gets too hot?

This is caused by overheating the transmission fluid. Not only is the temperature critical but also how long the transmission is exposed to the particular temperature. High heat will cause damage to seals, burnout clutches, clutches slip, seals harden, varnish forms and the fluid burns. Transmission Application Guide.

What should the transmission temp gauge be at?

Transmission Application Guide Transmission Temp Gauge Transmission Troubleshooting What is the optimum temperature for the longest life of the transmission? Keeping the transmission temperature between 175 and 200 degrees will allow the fluid to last the longest. This is the normal operating temperature for a transmission.

What happens if you don’t put coolant on your transmission?

However, if your transmission is slipping a lot or you are pulling something heavy, the coolant may not be enough to cool the transmission efficiency and the temperature may rise drastically to temperatures over 240 degrees.

What causes the transmission fluid to get hot?

Transmission fluid wears out over time and can become contaminated with dirt and grit. Additionally, burned transmission fluid results from transmission heat – and transmission heat results from low fluid or old, ineffective fluid that needs to be changed.

What can cause a car transmission to overheat?

Driving habits, conditions, and weather are other possible causes of transmission overheating. If your transmission is running hot, be aware of possible causes. Most transmission problems are a result of overheating. Reasons for overheating include low fluid levels, leaks, burned, old or dirty fluid, or problems with the solenoid.

Why does my transmission fluid smell like burning?

Either way, low or bad fluid can cause transmission heat, and transmission heat can burn the fluid – a vicious cycle that ends in transmission failure. Keep your transmission fluid clean and fresh and it most likely won’t burn. If the transmission fluid is burning, you will notice a strong smell that is difficult to describe, but can’t be missed.

How often should you change your transmission coolant?

Consider a transmission cooler to help your car’s cooling system. Your car’s radiator does the job of cooling the transmission, so be sure to maintain it. You should check the coolant from time to time, and change it about every two years. If you tow or haul heavy loads, consider getting a transmission cooler.
