Does the car transmission fluid need to be replaced?
3 Answers
Transmission fluid needs to be replaced. Here is the relevant information about transmission fluid replacement: 1. Dry dual-clutch transmissions and manual transmissions have similar structures, so they both use synthetic transmission fluid with a service life of approximately 150,000 kilometers. Most automatic transmissions require fluid replacement every 60,000 to 80,000 kilometers. 2. The transmission fluid replacement cycle is just a general guideline. Due to factors such as driving conditions and habits, the condition of the transmission fluid may vary. If the vehicle experiences issues like rough shifting, strong jerking sensations, or significantly increased noise during use, it is necessary to check whether the transmission fluid needs replacement. 3. There are three common methods for replacing transmission fluid in vehicles: (1) Gravity drain: Similar to changing engine oil, the transmission fluid drain bolt is loosened to drain the fluid, and then new fluid is added through the fill port. The drawback is that gravity draining does not completely remove all the old fluid. (2) Machine flush: A transmission flush machine is connected to the transmission's fluid lines, and new fluid is added to the machine. The new fluid is then used to "push" out the old fluid from the transmission. The advantage is a thorough replacement, but the process is time-consuming and requires more transmission fluid. (3) Removing the transmission pan: The advantage is that the transmission filter can be cleaned or replaced directly, and the replacement is more thorough. The downside is that the procedure is more complicated.
As a veteran driver with over a decade of experience, I firmly believe transmission fluid should be changed regularly. This oil lubricates the gears and shafts inside the transmission. Over time, it gets contaminated and loses effectiveness. Not changing it can lead to internal wear and even premature transmission failure. Personally, I change mine every 40,000 km or two years - the exact interval depends on the vehicle model and driving habits. Automatic transmissions are more sensitive than manuals. If you notice rough shifting or unusual noises while driving, it might indicate fluid issues. The replacement process isn't complicated, but I recommend having it done professionally as DIY attempts might damage seals. Remember, regular maintenance saves both headaches and money by avoiding costly major repairs.
Driving to and from work every day makes transmission fluid changes crucial for keeping your vehicle running smoothly. If you ask me, I'd say it's a must. The fluid acts like blood, nourishing the transmission, but over time metal particles can mix in and affect performance. My automatic transmission car gets its fluid changed at the dealership every 50,000 kilometers - it's affordable maintenance that prevents major issues. On occasional long highway trips, old fluid can cause sluggish gear shifts and increased fuel consumption. Don't forget to check your owner's manual for recommended intervals - don't delay too long. Fluid changes are basic maintenance that, when combined with other inspections, gives you greater peace of mind behind the wheel.
