Don’t Get it Wrong, This is the Difference between Transmission Oil vs Gear Oil!

In maintaining vehicle performance, the selection and maintenance of transmission oil and gear oil play a crucial role. However, vehicle owners are often confused about the differences between these two types of lubricants. Understanding the basic differences between transmission oil vs gear oil is important to keep your vehicle operating optimally and avoid unwanted damage.

These two oils have different roles in the vehicle system. Transmission oil is used to lubricate the gears in the transmission system, while axle oil is specifically designed to lubricate the gears in the axle or differential system. While both aim to lubricate vehicle components, the differences in function, mode of action, and oil specifications make them have different characteristics.

In this article TransTRACK, we will discuss in detail the differences between the two, including their respective functions, how they work, the required dosage, the recommended replacement time, and the appropriate oil specifications. By understanding these differences, it is hoped that readers can be smarter in maintaining their vehicles and keep the transmission and axle performance optimized. Let’s explore the differences between these two types of lubricants.

Definition of Transmission Oil vs Gear Oil

Transmission oil and axle oil are two different types of lubricants used in vehicles to lubricate certain components and maintain vehicle performance and reliability.

Transmission fluid is a specialized lubricant designed for use in the transmission system of a vehicle. The transmission system is responsible for transferring power from the engine to the wheels of the vehicle using various gears and mechanisms. Transmission fluid helps lubricate the gears in the transmission, reduce friction, cool components, and help smooth gear transitions. Transmission fluid usually has different characteristics depending on the type of vehicle transmission, such as manual transmission or automatic transmission.

Axle oil (also known as differential oil) is a lubricant specifically designed for use in a vehicle’s axle or differential system. The axle system allows the wheels of a vehicle to rotate at different speeds as the vehicle turns, thus allowing the wheels to rotate at different speeds in situations such as turning. Axle oil lubricates the teeth in the axle, helps prevent wear, reduces friction, and helps transfer power efficiently to the proper wheels.

Both are critical components in the vehicle system and should be selected according to the specifications recommended by the vehicle manufacturer. Proper oil use and regular maintenance will help extend the life and maintain the performance of the vehicle’s transmission and axle system.

Differences between Transmission Oil vs Gear Oil

Here are the differences between transmission oil vs gear oil based on several aspects:

By Function

• Transmission Oil: Serves to lubricate the gears in the transmission system, help smooth gear shifts, and cool transmission components.
• Axle Oil: Serves to lubricate the teeth in the axle or differential system, helps transfer power efficiently to the proper wheels, and prevents wear on axle components.

How Oil Works

• Transmission fluid: Usually contains special additives designed to handle the workload and operating conditions of the transmission, such as high pressure and high temperatures.
• Axle oil: Generally has strong lubrication properties and withstands high pressure and friction inside the axle or differential.

Oil Measurements

• Transmission Oil: Transmission oil dosage usually depends on the type and model of the vehicle and the specifications recommended by the manufacturer.
• Axle Oil: The axle oil dosage also depends on the vehicle make and model and manufacturer’s specifications, and is generally less than the transmission oil dosage.

Oil Change Time

• Transmission Oil: Transmission oil change times may vary depending on vehicle usage conditions and manufacturer recommendations, but generally range from 30,000 to 60,000 kilometers.
• Axle Oil: The timing of axle oil changes also depends on the manufacturer’s recommendations and the vehicle’s usage conditions, but can generally be done every 50,000 to 100,000 kilometers.

Oil Specifications

• Transmission fluid: Transmission fluid has certain specifications that must match the type of vehicle transmission, such as manual or automatic transmission, and must be selected according to the manufacturer’s recommendations.
• Axle oil: Axle oils also have specifications that should be considered according to the vehicle’s axle type and model, and should be selected according to the manufacturer’s recommendations.

By paying attention to these differences, vehicle owners can optimally select and maintain transmission oil and axle oil according to the needs and specifications of their vehicles.

Signs you need to change your Transmission Oil vs Gear Oil

The signs that indicate you need to change the transmission oil and axle oil in your vehicle can vary depending on the condition of the vehicle, the type of oil used, and the manufacturer’s specifications. However, here are some common signs that may indicate that it’s time to change the transmission oil and axle oil:

Signs to Change Transmission Oil

Here are the signs to change the transmission oil:

Oil Color and Condition

If the transmission oil has turned brown or black in color, or if there are visible impurities or metal particles in the oil when checked, it could be a sign that the oil should be replaced.

Burning Oil Odor

If you smell a fishy or unusual odor when using the transmission, it could indicate that the oil has been contaminated or burnt, which could be a sign that the oil needs to be changed.

Changes in Transmission Performance

If you start to notice symptoms such as unsmooth shifting, unusual noises or vibrations when operating the transmission, or increased roughness when shifting, it could indicate that the transmission oil has lost its ability to lubricate and maintain optimal performance.

Signs to Change the Axle Oil

Here are the signs to change the axle oil:

Oil Condition

If the axle oil looks dirty, dark in color, or has dirt and particles in the oil when checked, it could be a sign that the oil should be changed.

Burning or Fishy Oil Odor

An unusual odor or fishy smell when using the axle can also indicate that the oil has been contaminated or burnt, and needs to be replaced.

Unusual Sounds and Vibrations

If you start to hear strange sounds like rattling or detect unusual vibrations when using the axle, it could indicate that the oil has lost its ability to properly lubricate the components.

Changes in Vehicle Performance

If you notice a change in vehicle performance, such as a decrease in acceleration, an increase in fuel consumption, or a feeling of unsteadiness while driving, it could indicate a problem with the axle system that may require an oil change.

It is important to pay attention to these signs and refer to the maintenance schedule recommended by your vehicle manufacturer to change the transmission oil and axle oil in a timely manner to maintain the performance and reliability of your vehicle.

In vehicle maintenance, the selection and maintenance of transmission oil and axle oil play an important role in ensuring the performance and reliability of your vehicle. By understanding the differences between the two and the signs of when it’s time to change them, you can keep your vehicle’s transmission and axle systems operating properly.

However, to ensure that this maintenance is done in a timely manner and according to your vehicle’s needs, it is important to have a tool that can help you effectively monitor oil conditions and replacement schedules. One solution you can consider is using TransTRACK’s Fuel Monitoring service.
