Manual Transmission Oil: Signs You Need to Change, Functions, and Costs

An oil change is identical to engine oil, even though a car transmission is also an oil change. Just like automatic transmissions, manual transmission cars also require special oil. There are still many vehicle owners who do not know about manual car transmission oil. Check out this article for complete information about manual transmission oil.

There are many types of oil needed by a car, in order to operate normally, namely engine oil, axle oil, power steering oil, brake oil, and transmission oil. There are people who know more about automatic car transmission oil than manual car transmission oil,

Manual transmission, depending on the operation of the clutch and shifter by the driver whenever a gear shift is required. This type of transmission requires different fluids for best performance depending on the make, model and year of the car.

Function of Manual Car Transmission Oil

Before we talk about transmission oil, it helps us to know how to operate a vehicle's manual transmission.

Driving a car with a manual transmission requires the driver to move body parts from the feet to the hands. The way a manual transmission car works requires a harmonious movement between the two feet and the driver's left hand.

Manual cars usually have three pedals at the driver's foot. The right foot is usually used to step on the brake and gas pedals, and the left foot is specifically used to step on the clutch pedal.

Manual transmission cars also require that the left hand movement is always active, to move the transmission lever so that gear shifts occur.

To start a manual car, press the clutch pedal with your left foot and then your left hand moves the gear lever to 1st gear position. Then slowly lift your left foot off the clutch pedal. At the same time, slowly step on the gas pedal with your right foot.

Find a balance between the movement of the left foot lifting the clutch pedal, and the movement of the right foot stepping on the gas pedal, so that the car can go slowly. Do not immediately step on the gas pedal, just do it slowly adjust the speed.

If the car is moving steadily, then you can step on the gas pedal deeper to increase speed. If the sound of the engine is roaring, step on the clutch pedal again with your left foot and shift the gear lever to 2nd gear. Then step on the gas pedal slowly again using your right foot.

That's how the driver operates the manual transmission on a vehicle. Seeing how it operates, the manual transmission is very at risk of being damaged due to operating errors by the driver.

What Is the Function of Oil in a Manual Transmission System

In general, transmission oil serves to lubricate the components of the transmission system that work to change the gear ratio and increase speed.

This oil is in charge of facilitating the process of changing gears and also reducing friction. Transmission lubricant also plays a role in connecting the transmission to the axle.

Many people consider changing the manual transmission oil unnecessary, unlike automatic transmission cars. Yes, it is recommended to replace the automatic transmission oil when the odometer on the vehicle shows the number 80 thousand to 100 thousand kilometers.

In fact, manual cars also require a transmission oil change. Manual transmission oil must also be replaced periodically. This aims to keep the components in the transmission well maintained.

The following is a more complete explanation of the function of transmission oil for manual cars.

  1. Improve engine performance

If you are diligent in changing the transmission oil, you will feel the performance of your favorite manual car engine increases. Acceleration of the car becomes lighter, then the engine also feels smoother.

This condition is caused by additives in manual transmission oil which can make the transmission performance like new again in distributing engine power. In addition, oil that has gone bad and blackened can cause black smoke to come out of the exhaust.

  1. Maintain machine components

To avoid the appearance of harsh noises and heavy shifting, the manual transmission oil should be changed periodically.

Because manual transmission oil makes the friction in the manual transmission system smaller, so it can indirectly make the life of the manual transmission components more durable.

  1. Prevent engine down

Vehicles that get routine maintenance will have good engine performance. The car is not easy to break down and get off the engine. Do not let you have to do down the car engine.

If you plan to sell your favorite manual car, then dropping the engine can make the price of the car go down too. It's better to spend on regular maintenance, rather than the selling price of your car having to go down in the future due to having experienced a downturn in the engine.

  1. Prevents engine contamination by dust and dirt

Oil that is already bad can carry dust and dirt circulating in the transmission system. Dust and dirt can settle and corrode if left untreated for a long time. It can even cause corrosion which makes the transmission components become scuffed and damaged.

Sae Manual Transmission Oil

SAE stands for Society of Automotive Engineers, an international institution that regulates the standardization of the viscosity index of vehicle engine oils. SAE also regulates the standard of oil's ability to maintain viscosity stability when affected by engine temperature.

Different types of oil, different specifications. SAE manual transmission oils generally have an oil viscosity specification of SAE 40 or 90, while other types of oil such as axle oils use SAE 90 to 140.

Several other sources also state that the lubricant for a good manual transmission is one that uses natural ingredients with an oil viscosity above SAE 40.

When to Change Manual Transmission Oil

Manual cars are generally designed so that the manual transmission oil does not need to be changed too often. Usually after a distance of tens of thousands of kilometers of new manual transmission oil replaced. But in practice it turns out not to be so.

How Many Km to Change Manual Car Transmission Oil

Each car may have different manual transmission oil change regulations. Therefore, it is recommended that you read the user manual of the car. Generally in the manual it is usually recommended to change the manual transmission oil on the car when it has reached a distance of 40 thousand kilometers.

However, these numbers can be different when they are on the streets. The owners of this car are advised to change the manual transmission oil faster, such as once every 25 thousand kilometers or even 20 thousand kilometers.

But that time interval does not apply if you have felt the strangeness of the car's manual transmission. Here are some characteristics of your car's manual transmission oil that should be replaced immediately.

  1. Sound comes from the transmission

The sound that appears is the buzzing sound of the transmission. This buzzing sound usually appears rather loud when you are driving a car, and comes from the bottom of the car.

Just like other components, if it makes an unusual sound, you should take your car to a repair shop to check the transmission.

The hum of this transmission usually arises as a result of the contact between the gears in the transmission. This can happen if the quality of the manual transmission oil has decreased.

  1. Black oil color

Characteristics can be a sign of two things, namely the transmission oil is bad or the clutch lining is thin. But it will be easier and cheaper for you to change the manual transmission oil first. We recommend changing the manual transmission oil along with changing the oil on the axle as well.

It is highly recommended that you remember the last time you changed the transmission and axle oil. If the manual transmission oil and axle oil have been changed, it will usually be easier for you when you want to shift gears.

  1. Manual transmission vibrates

One more characteristic of your car's manual transmission oil that is no longer good is the appearance of vibration. The gears vibrate when in the idle or stationary position. The appearance of this vibration can come from various factors, one of which is the transmission oil or it can also come from the transmission mounting that is not good.

Before starting to check the manual transmission oil, your first step must have a measuring stick (dipstick), its function is to measure the condition of the manual transmission oil fluid.

Since most manual cars don't come with a transmission oil gauge, it's best to buy one separately.

Once you have the measuring stick, the second step is to remove the filler plug on the side or top of the transmission.

There is a hole where you can insert a dipstick, or your finger, to see if the fluid level is at the car manufacturer's recommended level.

You also have to observe the color and smell of the transmission lubricating oil. Transmission oil that is dark in color, or has a burning smell generally has a bad condition.

Also make sure the transmission oil does not contain metal powder or mud in it. The oil needs to be changed if it doesn't have a reddish tint, which means it's still in normal condition.

Find the position of the two holes. If you have trouble, you can look for the information in the vehicle manual or browse the internet from a smartphone. Generally the position of the fill plug is on the side of the transmission, while the drain plug is at the bottom of the transmission housing.

  1. Drain the old transmission oil

Prepare a large enough empty container. Then put the container for the used transmission oil liquid under the drain plug. Then open the drain plug bolt using a wrench.

You can also put a cloth over the container to filter the transmission oil that comes out. Check for metal debris or other material contamination in the used transmission oil fluid. If there is, immediately check with the repair shop for further action.

If no dirt is found, replace the drain plug bolt after all the transmission oil has been drained.

  1. Put in the new manual transmission oil

After confirming that the transmission tank is empty, unscrew the fill plug bolt using a wrench. Then pour the new manual transmission oil fluid into it. To fill the transmission oil, you can use tools such as hand pumps and hoses.

These two tools are very useful in helping to enter the transmission oil fluid into the transmission hole, so it doesn't spill or spill on the floor.

  1. Close and re-tighten the fill plug bolt

If you have done the steps above, reinstall the fill plug bolt and tighten it with a wrench so that the transmission fluid does not spill.
