How many liters of transmission fluid are needed for a Huansu S3 transmission fluid change?

[AveryMarie]

When changing the transmission fluid for a Huansu S3, approximately 4 to 6 liters are required for a manual fluid change (gravity drain method), while around 9 to 12 liters are needed if using a fluid exchange machine. The methods for changing transmission fluid are as follows: 1. Loosen the drain plug at the bottom of the transmission to drain the old fluid, then refill with new fluid. 2. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the first, as it allows for the removal of debris from the bottom of the oil pan. 3. Use a circulation machine to change automatic transmission fluid: A smart circulation machine performs a dynamic fluid exchange, filtering and cleaning sludge and debris from the automatic transmission. Hazards of not changing transmission fluid for an extended period: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impaired transmission operation, leading to damage to the transmission valve body.
