How Many Liters of Transmission Fluid Are Needed for Replacement?
2 Answers
Replacement methods for transmission fluid vary, and the required amount differs accordingly. Gravity drainage typically requires 6-7 liters, while a flush with a machine generally needs 12 liters. The steps for replacing transmission fluid are as follows: 1. Start the engine to warm it up, allowing the transmission to reach operating temperature; remove the drain bolt and collect the old fluid from the transmission; 2. Once the old fluid has completely drained, open the oil pan and replace the transmission filter; reinstall the oil pan and tighten the drain plug; 3. Add new transmission fluid; start the car and shift through all gears; 4. Check if the automatic transmission fluid level is normal and adjust as needed.
When it comes to changing transmission fluid, the amount really depends on the specific vehicle model and transmission type. Generally, automatic transmissions require about 5 to 7 liters, while manual transmissions may only need 3 to 5 liters, but SUVs or large vehicles might exceed 7 liters. In my work, I often see owners guessing the amount without checking the manual, leading to incorrect quantities that cause transmission slippage or leaks. The replacement process includes draining the old fluid, inspecting the filter screen, and adding new fluid, sometimes requiring the engine to be started for circulation to distribute the fluid evenly. It's recommended to change it every 50,000 kilometers; otherwise, aging fluid increases the risk of wear. Using the wrong type of fluid can also shorten the system's lifespan, so choosing branded fluid and reputable shops is key. Don’t underestimate this maintenance—it keeps your car running smoother.
