How Many Liters of Transmission Fluid Does the X-Trail Need for Replacement?

[Xavier]

The X-Trail generally requires an automatic transmission fluid change every two years or every 60,000 kilometers, with approximately 6 liters of transmission fluid needed. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the gear ratio between the output and input shafts, also known as the gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also featuring a power output mechanism. Most transmission mechanisms use ordinary gear transmission, while some employ planetary gear transmission. Ordinary gear transmission mechanisms typically use sliding gears and synchronizers. Under normal circumstances, automatic transmission fluid should be changed every 2 years or every 40,000 kilometers. For manual transmissions, it is generally recommended to change the transmission fluid every 3 years or every 100,000 kilometers, as the internal structure of manual transmissions is much simpler than that of automatic transmissions. Methods for replacing transmission fluid: Gravity Drain: After loosening the tightening nut at the bottom of the oil pan, the transmission fluid will automatically flow out from the drain hole. Machine Flush: Connect the transmission to a flushing machine via pipeline interfaces to push out the old fluid with new fluid. Oil Pan Removal: Remove the oil pan to replace the fluid. Reasons for regular transmission fluid replacement: Ensures smooth and seamless gear shifting, improving driving performance. Provides excellent oxidation resistance, reducing component rust. Offers superior protection for gear assemblies. Enhances anti-wear effects, extending the lifespan of the automatic transmission. Key points to note when replacing transmission fluid: During replacement, old transmission fluid and other impurities should be promptly cleaned, and specialized equipment should be used to prevent any impact on transmission performance. Select the same type of transmission fluid as originally specified for the vehicle. Manual transmission vehicles require manual transmission fluid, while automatic transmission vehicles need automatic transmission fluid. Choose the appropriate transmission fluid model; vehicles with manual-automatic transmissions must also use automatic transmission fluid.
