What are the steps for changing the transmission oil of a BYD F3?

[ElliottFitz]

The steps for changing the transmission oil of a BYD F3 are as follows: 1. Currently, there are two main methods for changing the transmission oil of an automatic transmission: gravity oil change and circulation machine oil change. Gravity oil change is similar to changing the engine oil, where the oil pan screw is removed to directly drain the old oil, and then new oil is added. The advantages of this method are simple operation, less oil consumption, and low cost; but the disadvantage is that the oil change rate is low, only about 50% of the old oil can be replaced, and the old oil remaining in the torque converter and valve body cannot be drained, so the effect of mixing old and new oil after gravity oil change is not very obvious. 2. Circulation machine oil change uses the function of the machine to circulate out the old oil inside the transmission. The advantage is that the oil change rate is high, reaching about 85%, and the effect after the change is obvious. The disadvantage is that the oil consumption is relatively large and the cost is high. Both methods can be used.
