Does BMW Need Transmission Fluid Replacement?
2 Answers
BMW transmission fluid requires replacement. Generally, BMW models should have their transmission fluid replaced after exceeding 60,000 kilometers in mileage, with specific details to be referred to in the vehicle's maintenance manual. Transmission fluid is an oil product that maintains the cleanliness of the gear system, ensuring the normal operation of the transmission and extending the lifespan of the transmission device. Relevant information is as follows: 1. For older BMW models, the regulations require mandatory transmission fluid replacement based on mileage. Typically, it should be replaced every 50,000 kilometers; 2. The current new 8-speed automatic transmission also adopts a maintenance-free design that does not require fluid replacement; 3. Its four-wheel drive mechanism is also maintenance-free and does not require replacement of the corresponding fluid.
I've been driving a BMW for several years, and the transmission fluid does need to be changed regularly. BMW's automatic transmissions are particularly precise. If the fluid ages and deteriorates, gear shifts can become very jerky, and internal components may even get damaged. Personally, I change it every 60,000 kilometers or so, and after the change, the car feels much smoother to drive. If you don't change the fluid for a long time, impurities in the fluid will accumulate, increasing friction and making the transmission prone to overheating or premature failure. Repairing a transmission can cost several thousand or even tens of thousands of yuan, so this maintenance expense is worth it. I recommend everyone check their owner's manual or consult a professional technician—don't wait until problems arise to regret it. Regular fluid changes can also help maintain the car's resale value, giving you peace of mind.
