What is transmission service: How to know if your transmission is faulty and needs a service

Many drivers opt to ignore gearbox problems to avoid the associated costs. They are, however, ignorant of the difficulties that may occur. Therefore, we’re here to tell you when to know if your car needs transmission service.

This article will explain what is a transmission service, how it is performed, and what the indicators of a bad transmission are, among other things.

Continue reading to see if you can find a useful remedy for your car’s transmission. Moreover, take a glance at the table of contents to see what the article has to offer.

What is transmission fluid?

Transmission fluid acts as a lubricant, allowing moving parts inside your car’s transmission to move freely. In an automatic transmission car, the fluid also serves as a coolant and performs a variety of additional functions.

When should you get your transmission service?

Instead of relying on third-party sources, check for information in the manufacturer’s manual. According to our research, every car manufacturer will recommend that the transmission be maintained at various periods. Furthermore, the transmission method varies based on whether you have an automatic or manual gearbox vehicle.

Four types of transmission service

These are the four most common transmissions available in the automotive industry. Moreover, we will also discuss what exactly they require.

Automatic transmission fluid exchange

The automatic transmission fluid is a sticky liquid that ensures the smooth operation of your car’s gearbox. The fluid works successfully due to the interaction of heat, friction, and time. The automatic transmission manual recommends checking and changing the fluid at regular intervals.

During the procedure, you must completely disconnect the transmission plugin to drain the old fluid. Furthermore, it is recommended that you check the power of the plug before reinstalling it to ensure that it is in good working condition. In case, if it is faulty., you should fill the plug with new, clean, and fresh fluid from a reputable source.

Automatic transmission filter and fluid replacement

A filter is mounted to the transmission. When the fluid in the system starts to circulate, it begins to remove debris and dirt from the transmission. However, you must pay close attention to the filter, as it will become unclean with time. In this case, make sure to clean it as well to maintain its great performance.

Remove the transmission pan first, then replace the old filter with a new one. Make sure it complies with the manufacturer’s guidelines and requirements. Furthermore, before reinstalling the transmission pan, you must remove the gasket material. Finally, you must re-fill the transmission with new, clean fluid.

Manual transmission service

The manual transmission’s mechanical operation is very similar to that of the automatic transmission. The important distinction, however, is the ‘CLUTCH’. Rather than the automobile doing it on its own, the driver is the one who interacts with this component.

Before you replace the fluid in a manual transmission, you must first separate the entire transmission system. It is also vital for you to determine whether the fluid’s grade is suitable.

Complete transmission service

The complete transmission service is the best method for cleaning the transmission. Not only would you change the transmission fluid and filter during this procedure, but you’d also inspect the rest of the car’s components to see if they’re working properly.

Furthermore, after removing the gasket, you should inspect the transmission’s pan and sump. You must also notice any transmission damage caused by friction or metal particles. If you discover that the transmission is not in perfect working order, we recommend that you take your vehicle to a reputable repair. This is the safest course of action to take.

What are the signs of a bad transmission?

You should be alerted if you notice these signs in your vehicle. Instead of delaying the repair, you should get your vehicle’s transmission checked before any big misery takes place.

Let’s discuss what could be the significant signs of a bad transmission;

Check engine light “ON”

The check engine light is installed in both older and newer vehicles. This is one of the ways to determine if your car’s transmission is malfunctioning. The check engine light, on the other hand, might be triggered by a variety of other issues.

However, if you see it, you should inspect your vehicle’s transmission.

Fluid leaking

The fluid begins to leak as a result of the car’s extensive use and lack of maintenance. This indicates that your car’s transmission needs to be checked or the fluid needs to be changed once you see it.

Trouble while shifting gears

The gearbox begins to jam. This occurs when there is insufficient fluid in the transmission, causing the smoothness to be interrupted. It should come as no surprise to you that your transmission needs to be serviced.

Burning smell

Maybe you haven’t replaced the fluid in a while, just like the engine oil. If you haven’t changed the fluid in a while, it can degrade and cause a burning smell, which is a clear indication of transmission malfunction.


In the same manner that you take care of your car’s outside, you must pay attention to the inside as well. Rather than ignoring the problem for a lengthy time, repair it as quickly as possible.

We hope that this information on what is transmission service has helped you realize the importance of a properly running transmission.
