How many liters of CVT transmission fluid are needed for a Corolla during replacement?
1 Answers
When replacing the CVT transmission fluid in a Corolla, manual fluid replacement (gravity drain) requires 4 to 6 liters; using a fluid exchange machine requires approximately 9 to 12 liters. Functions of transmission fluid: Reduce friction and wear, control clutch friction and synchronizer performance; bear loads (low-speed high torque, vibration loads), dissipate heat, reduce vibration and noise, remove contaminants at gear meshing points (cleaning function); prevent corrosion, pitting, and surface metal tearing, isolate metal surfaces to prevent direct metal-to-metal contact. Hazards of not replacing transmission fluid for an extended period: Damage to the transmission's shift control mechanism; abnormal wear of gears and clutch plates inside the transmission; impaired normal operation of the transmission, leading to damage to the transmission valve body. Methods for replacing transmission fluid are as follows: Loosen the drain plug at the bottom of the transmission to drain the fluid before refilling. Directly remove the transmission oil pan to drain and refill the fluid: this method is more thorough than the previous one, removing impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: dynamic fluid exchange with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.
