The Focus requires approximately 2 liters of transmission oil for manual transmissions and 5.5 liters for automatic transmissions. If using the circulating machine oil change method, around 10 liters may be needed. Transmission oil is essential for maintaining the cleanliness of the gear system, ensuring proper transmission operation, and extending the lifespan of the transmission components. The Focus is an A-segment family sedan with body dimensions of 4378mm in length, 1810mm in width, and 1468mm in height, featuring a wheelbase of 2705mm. In terms of safety, the Focus is equipped with keyless entry, one-touch start, TPMS tire pressure monitoring, EBD electronic brake-force distribution system, EPAS electric power-assisted steering system, and a lightweight suspension system with SLA short long arm blade rear independent suspension featuring an independent subframe.

I've studied maintenance data for many Ford models, and the transmission fluid quantity for the Focus depends on the specific model configuration. The manual transmission version is more fuel-efficient, requiring approximately 1.8-2.2 liters. If you're changing it yourself, buying two 1L bottles is sufficient. The automatic transmission fluid quantity varies significantly. The older 4AT requires a full 8 liters, while a recent change for a 2012 1.6L automatic model used 5.7 liters. The newer 6AT typically requires between 5.3-5.8 liters. The safest approach is to check your vehicle's maintenance manual or provide the VIN to parts suppliers for verification. Remember to select oil with the correct certification standard, such as MERCON-LV for DCT transmissions, as using the wrong oil can cause jerking.

Last week, I helped my neighbor replace the transmission fluid for a 2013 Focus. The actual drained old fluid measured 4.9 liters, and it took 5.2 liters of new fluid to reach the standard level. The fluid replacement volume for automatic transmissions varies significantly - the 1.6L engine with dual-clutch typically requires 4.5-5 liters, while the 2.0L models need about 0.3 liters more. Repair shops using fluid exchange machines for circulation cleaning should prepare 12 liters, but this thorough fluid replacement delivers excellent results. Reminder: The filler port is located inside the left front wheel. DIYers should prepare a ratchet wrench and special fluid filler tool. After refilling, remember to check the fluid level with the engine warmed up.

The transmission fluid volume is directly related to the oil change method. Gravity drain: 1.5-2L for manual transmissions, 4.5-6L for automatic transmissions; Machine flush: 8-12L for automatic transmissions. The 2010 Focus owner's manual specifies 7.3L for automatic transmissions including radiator line capacity. Recommended change interval is every 60,000 km using OEM WSS-M2C938-A certified fluid. After changing, cycle through all gears to circulate the fluid.
