Automatic Transmission

Did you see a small puddle of reddish fluid underneath your automated car? It indicates you have a leaky transmission. It isn't a good sign in simpler terms, and you need to get your transmission inspected right away.

Although transmission fluid leaking isn't dangerous, it won't let you drive your car with ease. The leaks will also form a stain either on the driveway or garage floor, which can serve as a reminder to get your transmission inspected.

If you're curious to know what causes transmission fluid to leak, this blog has valuable information for you.

How to Spot Transmission Fluid?

Before exploring the causes, it's essential to identify transmission fluid. The fluid plays a significant role as a multipurpose lubricant and hydraulic solution. It conditions seals and gaskets to elevate their lifespan.

Transmission fluids are said to have a red color. But the color varies from one manufacturer to another. Moreover, the fluid is thinner in consistency than engine oil and thicker than brake fluid.

Some Common Causes of Transmission Fluid Leaks

There might be minor issues causing a leaky transmission. However, you shouldn't ignore fluid leaks and opt for extensive inspection. Here is a list of some standard causes that tell when your transmission needs to be checked.

Cracks in Fluid Line

Transmission fluid lines are made of steel or aluminum. Therefore, there's no denying that these lines are durable. But if exposed to heat and road debris, these lines will get damaged or break completely.

Leakage of Torque Converter

Did you know transmission fluid move into the entire system through a torque converter? If your torque pump develops a crack on its body or its needle bearings get damaged, it'll contribute to transmission fluid leaking.

It isn't a simple task to fix torque converter leakage. Therefore, taking your vehicle to the mechanic for replacement sounds like the best solution.

Failure of Transmission Pan Gasket

Inadequate manufacturing, improper installation, or constant exposure to heat, these factors severely damage the gasket, contributing to a leaky transmission.

However, the pan gasket is reasonable to fix, so you need to do it right away. This way, you will prevent the occurrence of severe problems in the future.

Broken Seals

Your transmission sustains hydraulic pressure through various transmission seals. That's why it usually needs automatic transmission service. Over time, these seals develop cracks and get worn out, especially when exposed to heat. Suppose you get a transmission leak from this; you need to inspect many transmission areas.

The leaky seal will either in the input or output shaft. If not, you can also inspect plug seals, sensors, driveshaft, transmission pan, valve body, shifter housing seal, speedometer input seal, and tail housing seal.

Transmission Pan or Drain Plug

Transmission pans will experience some wear and tear over time. These pans are susceptible to damage from the debris on the road. Moreover, a leak can also occur if the pan gets a small puncture or there are loose drain plugs or bolts.

If it comes in contact with a big rock, your transmission will lose fluid in the blink of an eye. However, you'll know when this happens.

Road Accidents

Car accidents damage your car's internal parts. Some of these problems could lead to a leaky transmission. If your wheels or axles were hit in the accident, there are chances of fluid leak. Moreover, transmissions feature three output shafts.

And if one of these shafts got pushed hard in the accident, they damage transmission or seal, causing a leaky transmission. If you find pink fluid leaking out of your car, you need to get it fixed at the earliest.

Not Changing Fluid

As a car owner, you need to check your car's fluid regularly. You need to refer to your owner's manual as it tells how often transmission fluid needs to be changed.

Over time, the fluid accumulates metal particles during every day's drive. These particles lead to significant gasket or seal wear and tear. Therefore, it's best to change the fluid regularly to avoid unpleasant fluid issues.

Leaking Fluid Inspection Method

Professional mechanics don't take long to identify where and how the fluid is dripping from. The fluid often moves towards a path that is least resistant to it. Moreover, if a loose part is causing the leakage, your mechanic will tighten the loose part.

And if damages or cracks cause leaks, then you need to opt for replacement services. The mechanic will also give you an estimated cost of the process.

Summing it up!

It's best to know the causes that contribute to fluid leaking. This way, you will detect the leaks earliest and opt for the solution without further ado.

To avoid leaking problems, you can ask for its transmission inspection when you go for automatic transmission services. Keeping your transmission in good condition will prevent leakage and other issues, elevating its lifespan.
