How many liters of transmission fluid are needed for an Axela transmission fluid change?
2 Answers
For an Axela transmission fluid change, manual fluid replacement (gravity drain method) requires approximately 4 to 6 liters; using a fluid exchange machine requires about 9 to 12 liters. The methods for changing transmission fluid are as follows: Loosen the drain plug at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly for draining and refilling: This method is more thorough than the previous one, as it removes impurities accumulated at the bottom of the oil pan. Automatic transmission fluid exchange using a circulation machine: A smart circulation machine performs dynamic fluid exchange, filtering and cleaning sludge and impurities inside the automatic transmission. Transmission fluid reduces friction, minimizes wear, and controls clutch friction and synchronizer performance. It bears loads (low-speed high torque, vibrational stress), dissipates heat, reduces vibration and noise, and cleans contaminants from gear meshing areas (cleaning function). It prevents corrosion, pitting, and surface metal stripping, while isolating metal surfaces to prevent direct metal-to-metal contact.
My Mazda3 is the automatic transmission version. Last time at the shop, about 4 to 5 liters of transmission fluid were used for the replacement, employing the gravity drain method. The technician mentioned that if a flush machine were used, it would require 8 to 10 liters to thoroughly clean it out. The exact amount depends on the model year; generally, manual transmissions only need 2 to 3 liters. Not changing the transmission fluid can lead to overheating and damage components. It's recommended to have it checked approximately every 60,000 kilometers. After my replacement, the driving became much smoother. It's also crucial to choose the right fluid; the viscosity recommended by the manufacturer is best. Avoid using cheap, off-brand oils to prevent affecting shift precision.
