WHAT IS A SEALED TRANSMISSION?

A sealed transmission refers to a type of transmission that is designed to be completely sealed off from the external environment. This means that the transmission has a closed housing that does not allow any external contaminants, such as dust, dirt, or water, to enter the system.

Sealed transmissions are commonly found in modern vehicles and are typically designed to be maintenance-free. They are often filled with a specific type of transmission fluid that is designed to last for the life of the vehicle. This eliminates the need for regular transmission fluid changes and reduces the risk of internal damage due to contaminated fluid.

The use of a sealed transmission can help to improve the overall reliability and longevity of a vehicle’s transmission system. However, it is important to note that if a sealed transmission does develop a problem, it may require specialized tools and expertise to diagnose and repair the issue.

Why Do We Replace Transmission Fluid?

Transmission fluid is a critical component of a vehicle’s transmission system. It serves several important functions, including lubricating moving parts, cooling the transmission, and helping to transfer power from the engine to the wheels. Over time, the transmission fluid can become contaminated with debris, metal particles, and other impurities that can degrade its performance and reduce its ability to protect the transmission. This can lead to increased wear and tear on the transmission, reduced fuel efficiency, and potentially costly repairs.

Regularly replacing the transmission fluid can help to prevent these problems and extend the life of the transmission. By changing the fluid, you can remove contaminants and ensure that the fluid is able to perform its essential functions effectively. Additionally, replacing the fluid at regular intervals can help to identify potential issues before they become more serious problems, such as leaks or damage to the transmission itself.

It is important to follow the manufacturer’s recommended service interval for changing the transmission fluid. This can vary depending on the make and model of the vehicle, as well as the type of transmission fluid used. Failure to replace the transmission fluid as recommended can lead to serious damage to the transmission and potentially result in the need for costly repairs or replacement.

How Do We Replace Sealed Transmission Fluid?

Replacing the fluid in a sealed transmission can be a more complicated process than changing the fluid in a traditional, non-sealed transmission. Sealed transmissions are designed to be maintenance-free and typically do not have a dipstick or fill tube for adding or checking the transmission fluid level. Instead, the fluid level is typically checked and filled through a fill port located on the side of the transmission.

To replace the fluid in a sealed transmission, the vehicle may need to be lifted and supported on a hoist or jack stands, depending on the make and model of the vehicle. The technician will need to locate the fill port on the transmission, which may require the removal of a cover or other components to access.

Once the fill port is located, the technician will need to use a specialized tool to add the new fluid to the transmission. This may involve using a pressurized system to force the fluid into the transmission, or using a tool that attaches to the fill port and allows the fluid to be added under pressure.

It is important to use the correct type of transmission fluid when replacing the fluid in a sealed transmission. The manufacturer’s specifications should be followed carefully to ensure that the correct type of fluid is used and the correct amount is added to the transmission.

Because of the specialized tools and expertise required to replace the fluid in a sealed transmission, it is typically recommended that this service be performed by a qualified technician with experience working on sealed transmissions.

Can You Check the Transmission Fluid Yourself?

In a sealed transmission, it is not typically possible for a vehicle owner to check the transmission fluid level themselves, as there is no dipstick or fill tube accessible to the owner. Sealed transmissions are designed to be maintenance-free, and the fluid level is typically checked and filled through a fill port located on the side of the transmission.

However, some modern vehicles may have a sensor or display that allows the driver to check the transmission fluid level electronically. This information may be accessible through the vehicle’s onboard computer system or displayed on the dashboard.

If your vehicle does not have an electronic system for checking the transmission fluid level, it is generally recommended that you have the fluid level checked and serviced by a qualified technician. The technician will have the tools and expertise necessary to properly check the fluid level and add or replace fluid as needed.

It is important to follow the manufacturer’s recommended service interval for checking and replacing the transmission fluid. Neglecting to check or replace the fluid as recommended can lead to serious damage to the transmission and potentially result in costly repairs or replacement.
