You may be losing transmission fluid if your car has been parked for a few days and when you move it, you see fresh droplets or a puddle of fluid in your garage or on your driveway. Since most cars use a variety of fluids, it’s crucial to attempt and pinpoint the source of the leak.
Place some newspaper, a sizable piece of aluminum foil, or a clean piece of cardboard under your car when it’s parked for the night to check for transmission fluid leaks. It’s frequently a clue that there’s a transmission issue if the drips and stains you’re seeing are reddish, pink or light brown in color and appear to be coming more from the center of the automobile. In particular when it ages, transmission fluid becomes slick like motor oil and frequently has a burnt petroleum odor.
For the car to run, the fluid must remain at a specified level. Do you have any questions about the causes of transmission fluid leaks? The common causes, symptoms, and significant remedies for transmission fluid leaks are covered in this article.
What Causes Transmission Fluid Leak When Parked
Checking the level of the transmission fluid is a good part of taking care of your car. How did the transmission fluid start to leak? Well, it could be something small or something big. So, you should get the car checked as soon as you notice it. Still, here are a few things that can cause transmission fluid to leak.
Transmission Pan Is Worn Out
A worn transmission pan is one of the most common things that can cause transmission fluid to leak. This can also happen if the pan is in the wrong place. If the transmission fluid pan is used all the time, it may soon get holes or lose some bolts.
Different things can damage the pan, which can lead to problems with the transmission fluid. Basically, if you start to see this kind of leak, you should try to check the transmission fluid pan.
If the drain plug is not tightened, there may be a leak of transmission fluid. It can also be a problem if the drain plug is too tight, to the point where it breaks. These can cause a leak that lets transmission fluid out of the car. So, you should also look at it and fix it.
What kind of car transmission does your car have? In an automatic transmission, there is a steady flow of hydraulic pressure across the transmission seals. If these seals are exposed to heat for a long time, they may crack and start to leak.
The seals on the output and input shafts may be broken, so you should check these important parts. The shifter housing, the tail housing, and the speedometer input seal are some other places to check. You might also want to check the driveshaft and the sensors.
Broken Transmission Pan Gasket
Some cars’ gaskets aren’t made well, which makes them vulnerable to heat. Also, your car expert might have forgotten to make sure the gasket was in the right place the last time it was installed. No matter what is going on, this could be the cause of the leaks.
So, you need to get in touch with a professional auto mechanic. You may also notice that the gasket is damaged from being exposed to heat all the time. If you act quickly, you can fix this. Letting the leak go on for a long time can cause more problems with your car.
Fluid Line with a Crack
The smooth lines are made of aluminum or steel, so they will last for a long time. Still, the constant heat and debris from the road can cause the line to crack or even break completely. If the fluid line was broken, transmission fluid would leak.
The Torque Converter Has a Leak
The transmission fluid is pushed into the car’s system by the torque converter. So, a small crack in the body of the torque converter or worn-out needle bearings can cause it to leak. A broken torque converter needs to be replaced, so you should take your car to the mechanic.
Transmission fluid leaking: What to look for
There are many ways that transmission fluid can leak. You might start to notice a few signs that the transmission fluid in your car is leaking. Still, here are some common things you might notice.
Slow Getting Going
The car’s transmission makes sure that the engine and wheels both work at the same time. When there isn’t much transmission fluid left, it can be hard to change gears. When you step on the gas pedal, you might notice that your car isn’t going as fast as it used to.
Most of the time, “grinding gears” are caused by a bad Transmission Filter. But this can also be a sign of a leak in the transmission fluid. The vehicle’s gear is making a grinding sound because there isn’t enough lubrication and the fluid level is low. If you see this sign, you should get your car fixed quickly.
The Transmission System Is Making Too Much Heat
Have you noticed that the transmission system in your car is giving off too much heat? It could be because of a leak in the transmission fluid or a major problem with the car’s transmission. It’s not very common for the transmission system to get hot, as this can cause a lot of damage to the car.
So, you should keep a close eye on the heat gauge on the dashboard. You can also tell if the transmission is getting too hot if you start to notice a strange burnt smell. So, you would need to fix the car quickly to avoid more problems.
There’s a Puddle under the Car
This seems to be one of the most obvious signs that your transmission fluid is leaking. Depending on the transmission fluid you use, the fluid on the ground will be a different color. You might see a puddle of fluid that is red, brown, pink, or even green.
When you see a puddle of green or red fluid, it might not be coming from the transmission. Some of the parts inside of a car, like the steering, use transmission fluid.
Since there isn’t much transmission fluid left, you may soon feel strange vibrations when you shift into gear. If you see this, it could mean that your car’s transmission fluid is leaking. Soon, your car’s speed will slow down.
Along with this, the transmission is making a clunking sound, which is a clear sign that your car needs to be fixed. It doesn’t look safe to drive with such a sign, so you should fix this problem as soon as possible.
What to do When Transmission Fluid is Leaking When Parked
If you notice a transmission fluid leak when your vehicle is parked, here are some steps you can take:
- Identify the source of the leak: Look for any visible signs of a leak, such as a puddle under the vehicle or a wet spot on the transmission. If you can’t see the source, try wiping down the area with a clean cloth and looking for any fresh fluid that appears.
- Check the transmission fluid level: If the fluid level is low, it could be causing the leak. If the level is low, add more fluid to the transmission until it reaches the proper level.
- Repair the leak: Once you have identified the source of the leak, you will need to repair it. Depending on the severity of the leak, this may involve replacing a seal, gasket, or another component.
- Monitor the transmission fluid level: After you have repaired the leak, check the fluid level regularly to ensure it stays at the proper level. If you notice the level drops quickly, it could be an indication of a new leak.
- Get the vehicle checked by a mechanic: If you are unable to identify the source of the leak or if you are unable to fix it yourself, it is best to have a mechanic check the vehicle. A professional can diagnose the problem and make any necessary repairs.
