Causes of Transmission Fluid Leaks, gNewscar – Your car might have a transmission fluid leak for various reasons, but before we talk about why your car has a transmission fluid leak, it’s important to talk about how to identify that one. You will notice poor transmission fluid leaks when parked for a long time. Usually you will see some brownish or distinctive smelling oil on the garage floor or parking floor when you move your car.
These transmission oil liquids are often dark brown or red in color and have a distinctly unpleasant odor. This does not guarantee transmission leaks, because many power steering systems also use transmission fluid as a working fluid. Even though you might notice when the transmission fluid is leaking, first make sure you experience a slow leak? Because if so, you might have a shift problem or you might not have another indication that something is wrong.
Because these symptoms can be misleading, it is important to thoroughly check your transmission fluid level and look for other signs of leakage.
On most cars, you can check the transmission fluid level using a dipstick as well as check engine oil. Dipsticks often have a different color or say “trans” on the handle and will point toward the middle or back of your engine compartment. You should check the liquid level when your car is warmed, after driving 20-30 minutes, and with the engine idling at the ground level. If the level is low, the only cause is leakage. It is important to stop leaks quickly so that your transmission fluid is at the correct level to prevent damage to your transmission.
3 Main Causes of Transmission Fluid Leaks
Too long to replace the transmission fluid
One of the main causes is not hanging your transmission fluid often enough. Your vehicle owner’s manual will give you a recommended service interval to replace your transmission fluid in normal and extreme driving conditions. If you are wondering how often you need to replace your transmission fluid, most vehicle owner manuals can be found easily online!
As you drive, your transmission fluid picks up small pieces of metal as components in the wear-resistant engine box. If you don’t change fluid often, these metal flakes increase and can begin to damage the seals and gaskets in your transmission prematurely.
Impact of a violent impact or accident
If one of your wheels or axles crashes during an accident, it can cause the transmission fluid to leak. Your transmission has between 1 and 3 output shafts which are driveshafts or differential shafts coming out to your wheels. If one of these shafts is pushed in or jolted hard enough they can damage the seal in your transmission which causes leakage after an accident. If you suspect this to be the cause of your leak, it is often best to replace the seal and check the transmission gap for damage or damage.
Normal wear can cause transmission fluid leaks simply because of your transmission operating environment. For example, the output shaft are all in direct contact with the seal around them so that the movement of the shaft will eventually damage the seal and cause leakage. Also, temperature changes and constant transmission shifts can cause movement between seals and gaskets in your transmission which ultimately leads to leakage as well.
Often, replacing a gasket or seal that leaks in your transmission can be very expensive because of the labor costs associated with repairs. A cheaper way to cover your current leak, or prevent problems from appearing in the future due to leakage transmission fluid in your car.
Causes of Matic Car Transmission Oil Leaks
A cracked gasket plate or plate.
When there is some kind of friction in the gasket, you have to replace it, because the liquid inside will continue to seep out. This cause is easily corrected. All you need to do is buy a new gasket (which is relatively cheap). Also, make sure the bolts on the plate are tight enough. If not, this can cause leakage. Often the plates are not properly secured after the transmission fluid has changed, causing transmission leaks to occur. All you need to do here is tighten the bolt, which is simple. If this problem is not resolved immediately it can cause a lot of damage.
There is a problem with the torsion or torque of the vehicle converter.
Inside the torque converter there is a hydraulic pump that produces pressure in the transmission. This pressure then transmits the liquid throughout the system. If there is a gap in the converter body or there is a problem with the needle bearing, the transmission will leak. It is usually difficult to determine the transmission leakage to the torque converter and once it works, it is very expensive to fix it because it needs to be replaced completely.
Damage to the Fluid Channel
Transmission fluid lines are made to last because they are made of aluminum or steel. However, if it becomes damaged due to excessive heat exposure or scattered debris, the channel will eventually crack and then leak. Even hard aluminum or steel will not be strong enough to prevent it.
Obsolete Transmission Plates
The transmission fluid pan or pan will eventually wear out. Because the pan contains lots of small bolts and drain plugs, leakage can easily occur if one of these parts becomes loose or damaged. In fact, the plate itself can be damaged if you continue to drive on rough or uneven roads. This type of road has a lot of debris and rocks which will significantly damage the pot and cause leakage. If you only have loose bolts, then you might be able to improve the situation just by tightening it. But if you lose these parts, then you have to replace them. However, you have to replace your liquid too.
Crack Transmission Seal
Automatic transmission seals keep hydraulic pressure the same. The only problem is that this seal is constantly exposed to heat while the transmission is operating. Seals will eventually get to the point where they will wear out and crack from all these long-term heat exposure. The seal will then leak the transmission fluid.
How to Stop an Automatic Transmission Leak?
Although you can learn how to repair transmission leaks, it is also important to know how to stop transmission fluid leaks before they occur.
1. It is important to check the level of your transmission fluid at each oil change.
2. Pay attention to the color of your transmission fluid. The new liquid is bright red and translucent. If the liquid is more opaque or turns brown or black, it’s time to replace it.
3. A common cause of transmission fluid leakage is constant wear on the rubber seal. Once the seal gives way to your transmission, the liquid will start to leak.
