How Many Liters of Oil Are Needed for a Manual Transmission Oil Change?

[Talia]

Manual transmission oil change (gravity method) requires four to six liters; using an oil change machine requires approximately nine to twelve liters. The methods for changing transmission oil are as follows: Loosen the drain screw at the bottom of the transmission to drain the oil, then refill. Directly remove the transmission oil pan to drain and refill: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Using a circulation machine to change automatic transmission oil: Dynamic oil change with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. Transmission oil can reduce friction, minimize wear, control clutch friction, and optimize synchronizer performance. It also supports load-bearing (low-speed high torque, vibration loads), heat dissipation, reduces vibration and noise, and cleans contaminants from gear meshing areas (cleaning function). Additionally, it prevents corrosion, pitting, and surface metal tearing, while isolating metal surfaces to prevent direct metal-to-metal contact.
