How to Maintain the Inside of a Transmission?

The internal maintenance of a transmission involves cleaning and replacing the lubricating oil, as well as checking whether the fasteners of the transmission assembly are loose and whether there is oil leakage at the joint surfaces and oil seals. Below is relevant information about transmissions: 1. As one of the important components of a car, the transmission has a significant impact on the vehicle. Like the engine, the transmission requires regular oil changes, which can extend the vehicle's service life to a certain extent. 2. Manual transmission: If the transmission uses mineral gear oil, the transmission oil should be changed every 3 years or 60,000 kilometers. If synthetic oil is used, the transmission oil should be checked regularly, and it can be used continuously as long as the oil quality is good. 3. Automatic transmission: For most brands, automatic transmission vehicles require a transmission oil change every 4 years or 60,000-80,000 kilometers. 4. CVT transmission: Due to its simple structure and the use of synthetic transmission oil, the replacement interval is longer than that of an automatic transmission, with a suitable interval of 80,000-100,000 kilometers. Since dual-clutch transmissions come in dry and wet types, their maintenance methods differ. Dry dual-clutch transmissions do not require oil changes, while wet dual-clutch transmissions need to have the transmission oil and filter replaced every 60,000 kilometers, similar to automatic transmissions.
As a driver with twenty years of experience, I can say that the key to internal transmission maintenance is regular oil changes and maintaining good driving habits. I remember when I first bought my car, I didn’t pay attention, and the transmission oil aged without being replaced, resulting in increased internal friction and severe gear-shifting hesitation. Later, I started going to a professional shop to change the oil every two years or around 30,000 kilometers, and also had the filter checked for blockages. Accumulated sludge can clog internal passages, causing the transmission to overheat. When driving, avoid aggressive acceleration or deceleration—smooth driving reduces wear. Regular maintenance can extend the transmission’s lifespan by over ten years. Don’t skimp on small expenses only to incur big costs later; just find a reliable technician to handle it.
From the perspective of a car maintenance enthusiast, let's talk about internal transmission maintenance: The core task is replacing the transmission fluid. It's crucial to follow the manual's recommended mileage and fluid type. For instance, some vehicles use ATF fluid, and using one that's too thick can lead to poor lubrication. Don't forget to replace the filter as well—it traps metal particles to prevent internal wear. In daily driving, avoid frequent starts in heavy traffic or overloading, as these increase internal pressure. When checking the fluid level, do it when the engine is cold using the dipstick. If the fluid appears dark or murky, it's time for a change. Proper maintenance like this ensures much smoother transmission operation.
