How Much Oil Should Be Added to the Equipment Transmission?
2 Answers
There are two methods: gravity oil change generally requires 3-5L, while machine circulation oil change requires 12L. Here is a partial introduction about adding oil to the equipment transmission: 1. Gravity Oil Change: Similar to changing engine oil, this method is the most convenient and cost-effective, usually requiring only 3 to 5 liters of transmission oil. However, the downside is that gravity draining does not completely remove the old oil, only about one-third of the original oil can be drained. The remaining oil, which cannot be drained through the active transmission oil pan, is the dirtiest part. 2. Machine Circulation Oil Change: This method involves connecting a transmission circulation machine to the transmission's oil circuit interface. New oil is added to the circulation machine, which then "pushes" the old oil out of the transmission. It cleans and removes metal impurities and sludge from the transmission torque converter and oil passages. The dirtier the oil that comes out, the cleaner the transmission becomes. This method requires approximately 12 liters or even more transmission oil. The more oil used, the cleaner the transmission becomes.
Last time I changed the transmission fluid, I was also quite puzzled by this issue. After checking the vehicle manual, I realized the required fluid volume varies significantly between different models. My manual transmission compact car needed less than 2 liters, while my neighbor's automatic transmission SUV required over 7 liters. The most reliable approach is to consult the manual for the manufacturer's recommended quantity or simply provide your vehicle model to the repair shop for clarification. If doing it yourself, pay attention - the filler hole is usually located on the side, and you need to level the car before adding fluid. Insufficient fluid leads to inadequate lubrication and accelerated wear, while overfilling may cause gear agitation and foam formation, which actually impairs heat dissipation. After filling, I specifically ran the engine for a few minutes before rechecking the dipstick to ensure both cold and hot fluid levels were within the middle range of the scale before feeling assured.
