How Often Should You Change Your Car's Transmission Fluid?
2 Answers
Car transmission fluid should be changed every 40,000 kilometers. Transmission fluid is a lubricant that keeps the gear system clean, lubricates to extend the lifespan of the transmission components, and provides effective lubrication even in low-temperature conditions, reducing fluid loss under harsh operating conditions. Depending on the transmission structure, transmission fluid is categorized into automatic transmission fluid (ATF) and manual transmission fluid. ATF is specifically designed for automatic transmissions, while manual transmission fluid, commonly referred to as gear oil, is used for lubricating hypoid gear drive shafts and manual transmissions that operate under severe high-impact conditions.
I've gained some experience over the years when it comes to transmission fluid changes. Generally speaking, it should be replaced every 30,000 to 60,000 kilometers, depending on the vehicle model and owner's manual. Automatic transmissions require more frequent changes, while manuals are slightly more forgiving. Once, my old car went over 50,000 km without a change, and it started jerking badly during gear shifts. Upon inspection, the fluid was black with a burnt smell - lubrication failure had caused internal wear, costing me nearly 8,000 yuan in repairs. Prevention is key: regularly check the fluid level and color - bright red is good, while brown or foul-smelling means it's time for a change. If you frequently drive in city traffic with constant gear shifts accelerating fluid degradation, consider shortening the interval. Extreme driving conditions like heavy towing or long mountain trips also warrant earlier replacements. Don't penny-pinch - a few hundred yuan for maintenance can prevent tens of thousands in repairs and extend your transmission's lifespan by years. Remember, the best approach combines the manual's guidance with your personal driving habits.
