How many liters of transmission fluid are needed for an Envision 28T transmission fluid change?

[VonSamuel]

If it is a manual fluid change (gravity drain), four to six liters are required; if a fluid exchange machine is used, approximately nine to twelve liters are needed. The methods for changing transmission fluid are as follows: Loosen the drain plug at the bottom of the transmission to drain the fluid, then refill. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a transmission fluid exchange machine for automatic transmission fluid changes: A smart exchange machine can perform dynamic fluid changes, filtering and cleaning sludge and impurities inside the automatic transmission. Hazards of not changing transmission fluid for a long time: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission valve body.
