Should Transmission Fluid Be Changed During the First Maintenance of a New Car?

Transmission fluid does not need to be changed during the first maintenance. Below is relevant information about the transmission: Introduction: The transmission is a very important component of a vehicle, capable of altering the gear ratio and expanding the torque and speed of the drive wheels. With the advancement of modern technology, transmissions have also been upgraded, evolving from the original manual transmissions to the current continuously variable transmissions, and from non-synchronized to synchronized transmissions, making operation increasingly convenient. Working Principle: Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT), on the other hand, are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.

As a car enthusiast who treats my vehicle like my own life for years, there's no need to worry about transmission fluid during the first maintenance of a new car. Modern vehicles are well-designed, with transmission fluid lasting up to 40,000 kilometers or even longer. The first maintenance usually occurs at only 5,000 to 10,000 kilometers, typically involving tasks like engine oil change and filter cleaning. The manual is the bible, clearly listing different models such as sedans or SUVs. For instance, my experience shows that long-term components like automatic transmission fluid have extended replacement intervals. Changing them unnecessarily not only wastes money but may also cause oil passage blockage or excessive wear, damaging the transmission. As the saying goes, flipping through the user manual or consulting experts at a trusted repair shop is the safest approach. Don't blindly follow online rumors and mess things up.

As an automotive technology enthusiast, I'm well-versed in maintenance intervals. For a new car's first service, there's absolutely no need to change the transmission fluid, because manufacturers specifically design the fluid to last tens of thousands of kilometers considering transmission durability. The primary tasks during the first service are changing the engine oil and filter to ensure proper component break-in. You can check the manual for specific instructions; changing transmission fluid prematurely is completely unnecessary and might even affect oil pressure balance. Even for high-performance vehicles like sports cars, the difference isn't significant – I've tested several, and just checking for leaks as needed suffices. Regularly monitoring fluid conditions saves both money and hassle.

The first maintenance of a new car does not include transmission fluid replacement. The owner's manual specifies that the primary focus of the initial maintenance is engine oil replacement. Transmission fluid has strong durability and only needs to be addressed at the designated mileage. The manual is the authoritative reference.
