How Much Oil Should Be Added to the Transmission?
2 Answers
Transmission oil quantity varies by method: manual oil change (gravity method) requires 4-6 liters, while machine-assisted oil change needs approximately 9-12 liters. Introduction to Transmission Oil: Transmission oil is a lubricant that maintains the cleanliness of the gear system, ensuring proper transmission operation and extending the lifespan of the transmission components. Methods for Changing Transmission Oil: 1. Drain the oil by loosening the drain plug at the bottom of the transmission, then refill. 2. Remove the transmission oil pan for draining and refilling: This method is more thorough than the first, as it removes impurities accumulated at the bottom of the oil pan. 3. Use a circulation machine for automatic transmission oil change: A smart circulation machine performs dynamic oil change, filtering and cleaning sludge and impurities inside the automatic transmission. Replacement intervals vary by vehicle type. Below are the recommended intervals for transmission oil changes: Manual Transmission: Generally recommended every 3 years or 100,000 kilometers. Automatic Transmission: Generally recommended every 2 years or 40,000 kilometers. Continuously Variable Transmission (CVT): Generally recommended every 2 years or 60,000 kilometers.
The transmission fluid amount isn't a one-size-fits-all number. Based on my years of driving experience, manual transmissions typically take 2 to 4 liters, while automatics range between 4 to 8 liters - the exact amount depends on the vehicle model and year. My old car was a manual, and I always used the dipstick to ensure the level stayed between the marks during oil changes. If underfilled, the transmission can overheat or even seize up - once I neglected this and ended up stranded with costly repairs. Automatic transmissions are more sensitive; incorrect fluid levels can cause foaming or leaks leading to rough shifting. I recommend checking fluid level and color every 40,000 km - replace if it appears too dark or thick. Never eyeball the amount, especially with older vehicles that may consume more fluid than new ones. Bottom line: always follow the manual for safety - never cut corners for convenience.
