Ford Focus transmission fluid should be changed every 3 years or 60,000 kilometers. Below is an introduction to automotive transmissions: 1. Introduction: An automotive transmission is a gear-shifting device used to coordinate the engine's speed with the actual driving speed of the wheels, optimizing the engine's performance. The transmission can produce different gear ratios between the engine and the wheels during vehicle operation. 2. Function: It alters the transmission ratio to expand the range of torque and speed variations of the driving wheels, adapting to frequently changing driving conditions while allowing the engine to operate under favorable conditions (higher power and lower fuel consumption).

I've been driving a Ford Focus for ten years, and the transmission fluid change is generally determined by mileage. The official Ford manual recommends changing it every 70,000 to 100,000 kilometers. My own car gets it changed every 80,000 kilometers to keep the transmission running smoothly. Don’t delay too long, as old fluid accumulates impurities, affecting shift precision and potentially damaging the gearbox, which can be costly to repair. Pay attention to whether shifting feels rough or if there are unusual noises while driving—these are signs that you need a fluid change. If you frequently drive in congested urban areas, the fluid gets dirty faster, so it’s advisable to check it at 60,000 kilometers. Regular maintenance extends your car’s lifespan, saving you money and giving you peace of mind.

I've repaired quite a few Focus models, and when to change the transmission fluid depends on usage. It's recommended to change it every 60,000 to 80,000 kilometers. Transmission fluid lubricates internal components to prevent wear. Overuse can degrade the fluid, leading to sluggish shifting or excessive vibration. When changing the fluid, use specialized equipment to drain the old fluid and refill with new fluid. Never mix types—automatic and manual transmissions require different specifications. Timely changes avoid major repairs, as transmission fixes can cost thousands, which isn't worth it. Also, check the fluid level and color—clean and transparent is normal, while dark and murky means it's time for a change. This habit ensures driving safety and a more comfortable ride.

We use our Ford Focus as a daily commuter car, and it has been over four years. According to the Ford manual, it's appropriate to change the transmission fluid every 5 to 6 years or 60,000 kilometers. For a commuter tool like ours, timely fluid changes ensure smooth gear shifts and safe driving. Don't overlook the small things—old fluid can cause the transmission to overheat and seize up, leading to risks. I make it a habit to check during maintenance; if the fluid is clear, it's fine, but if it's cloudy, it needs attention. Keeping it in good condition makes driving the kids to school more reliable and worry-free.
