What oil is transmission oil
Transmission oil is a special lubricating oil used in vehicle transmission systems, which is mainly used to lubricate and cool transmission components such as transmissions and differentials. Its main functions are to reduce friction, prevent wear, dissipate heat and keep the transmission system clean. Different types of vehicles and drivetrains require different specifications of transmission oil, so choosing the right transmission oil is crucial to the performance and life of the vehicle.

Types of transmission oil
Transmission oil can be divided into the following categories according to the use scenario and performance requirements:
| type | Applicable scenarios | Features |
|---|---|---|
| Automatic transmission oil (ATF) | Automatic transmission | It has high antioxidant and foam resistance |
| Manual transmission oil (MTF) | Manual transmission | High viscosity, suitable for high load conditions |
| Differential oil | Differential | Contains extreme pressure additives, suitable for high torque scenarios |
How to choose transmission oil
When choosing transmission oil, the following factors need to be considered:
1.Vehicle manufacturer recommendations: Different models have different requirements for transmission oil, so the recommendations in the vehicle instructions should be preferred.
2.Transmission oil specifications: Transmission oil usually has API, SAE and other standards to ensure that the selected oil meets the specifications.
3.Usage environment: In high or low temperature environments, the transmission oil with corresponding performance needs to be selected.
4.Replacement cycle: The transmission oil will gradually age with the use time, and regular replacement is the key to ensuring the health of the transmission system.
How to replace transmission oil
Replacing the transmission oil usually requires the following steps:
1.Preparation tools: Including suitable transmission oil, oil pan gasket, filter, etc.
2.Emission of old oil: Lift the vehicle, find the transmission oil discharge port, and release the old oil.
3.Replace the filter: If the transmission system has a filter, it needs to be replaced.
4.Add new oil: Inject new oil through the gas refueling port to ensure that the oil volume is within the standard range.
5.Check for leaks: Start the vehicle and check for leakage.
FAQ
1.What is the difference between transmission oil and engine oil?
Transmission oil is mainly used to lubricate the transmission system, while engine oil is used to lubricate the internal components of the engine. The formula and performance requirements of the two are different and cannot be mixed.
2.How often does the transmission oil need to be replaced?
It is generally recommended to replace it every 40,000 to 60,000 kilometers, and the specific details are subject to the vehicle instructions.
3.Does the transmission oil need to be replaced if it turns black?
It is usually normal to turn black in the transmission oil, but if it is accompanied by odor or impurities, it needs to be replaced in time.
Through the above content, I believe everyone has a deeper understanding of transmission oil. Choosing the right transmission oil and replacing it regularly can effectively extend the service life of the vehicle's transmission system and improve the driving experience.
