What Causes Transmission To Overheat?

What causes transmissions to overheat? 

 Transmission overheat because of internal issues. These issues usually begin with neglected services and maintenance such as leaks causing low fluid levels, worn out fluid, clutch material and metal shavings in the fluid, and a occasionally a overfilled transmission.

There are a few signs that your transmission is overheating. The first sign is a smell of burning fluid, which doesn’t have a good odor, which you may notice outside of your vehicle. Another sign is when your you notice your tranny is slipping. And, if you feel harsh  or elongated shifting, your transmission is probably overheating as well from the extra work it has to do.

The transmission will begin to overheat when it has reached a temperature of 270 degrees or higher. Transmissions will last anywhere from 10,000 miles to 200,000 miles. It all depends on how well you maintain them. Every 60,000 to 100,000 miles, your transmission fluid needs to be changed. If not, you risk your transmission failing, requiring transmission repair.

There are a few factors that may cause a transmission to slip. The most popular reason is because of your transmission fluid. Your transmission fluid could be empty, dirty, or, it could be burnt. Another reason for transmission slipping is because of broken or worn-out transmission bands. This factor is most common in older transaxles.
 
A malfunctioning torque converter is another possible reason for transmission slipping. The torque converter is filled with transmission fluid. Its job is to create hydraulic pressure for the automobile. A slipping clutch is another reason for your transmission slipping.  Faulty shift solenoids are yet another reason for your transmission slipping. 

What happens to transmission fluid when it overheats?

At 240 degrees, your transmission fluid will begin to overheat. This will then cause the formation of varnish, seals will begin to harden, plates will slip, clutches and seals will burn out, carbon will be formed, and in the end, your transmission will fail. 

Trans fluid lubricates the operating parts inside your transmission. It also creates hydraulic pressure inside the unit. Transaxle fluid will overheat if it’s old, worn out, or burned. Later on, this will cause your vehicle to slip, and eventually fail to operate. 

What do you do when the transmission fluid overheats? 

Transmission fluid is supposed to lubricate the moving parts inside your transmission, if it’s unable to do so, it could cause major problems. 

Some of these problems include transmission failure, engine failure, and gear spillage. We advise having transmission fluid service done every 60,000 miles so these sorts of things don’t happen. 

If your transmission fluid overheats, it is most likely dirty or old. When it overheats, we recommend having it refilled immediately! This way, more challenging tasks don’t occur.

What happens when transmission overheat? 

Transmissions overheat because of many reasons. The most common reason is low trans fluid. When there is little to no fluid in your transaxle, there will be too much friction between the transmission’s moving parts, thus causing the transmission to overheat. 

If the transmission is unable to cool the engine, it could catastrophic failure which could lead to heavy transmission service or even transmission replacement. Also, the transmission wouldn’t be able to perform such tasks it is supposed to be able to do, which could lead to horrible, unsafe, problems.
