How often should the transmission be serviced?
2 Answers
The transmission should be serviced every 2 years or every 40,000 kilometers. Different vehicle models have different requirements, and the appropriate maintenance time for the automatic transmission can be reasonably selected based on the recommendations in the maintenance manual. Below is additional information about the transmission: 1. Transmissions are divided into manual and automatic. 2. Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. 3. Automatic transmissions are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system. 4. The function of the transmission is to change the transmission ratio, expand the range of torque and speed changes of the driving wheels to adapt to frequently changing driving conditions, while allowing the engine to operate under favorable conditions.
I'm an old-timer with decades of driving experience, and transmission maintenance is no joke. The manual usually says every 30,000 to 60,000 miles, but I learned the hard way when I neglected it in my younger days—my automatic transmission started shifting roughly, costing me thousands to fix. Automatic transmissions wear faster, especially with stop-and-go city driving, so changing the fluid every 40,000 miles is wise. Manuals are more forgiving, stretching to 60,000 miles. Driving habits matter too—towing heavy loads or frequent long trips mean more frequent checks. Old fluid, like engine oil, wears out parts if not replaced. Spending a few hundred on fresh fluid can save you big bucks. Don’t wait for trouble—regular checks keep shifts smooth, your drive worry-free, and safer too.
