Does a manual transmission require gearbox oil change?

[LeJack]

Manual transmissions do require gearbox oil changes. Extended relevant information is as follows: 1. The replacement cycle for manual transmission fluid is relatively long, typically every 2-4 years or 60,000 kilometers. If usage intensity is low, it can generally be changed every 100,000 kilometers, while under high-intensity use, replacement may be needed every 60,000-80,000 kilometers. 2. The hazards of not changing transmission fluid are as follows: (1) Prolonged failure to change transmission fluid may result in weak acceleration when starting the vehicle cold. (2) Long-term neglect of transmission fluid changes can cause the fluid to thicken, potentially obstructing the transmission cooler and leading to excessively high fluid temperatures, which accelerates wear.
