How Many Liters of Transmission Fluid Are Needed for Gravity Drain?
1 Answers
6-7L is the required amount of transmission fluid for a gravity drain. Gravity draining involves loosening the drain plug on the transmission oil pan to allow the fluid to flow out under gravity, then refilling the transmission through the fill port. The advantage of this gravity drain method is that the operation is relatively simple and requires a smaller amount of fluid. The downside is that not all the old fluid is drained, leading to a mix of old and new fluid, which shortens the transmission maintenance interval. Functions of transmission fluid: Reduce friction and wear, control clutch friction and synchronizer performance. Load-bearing (low-speed high torque, vibration loads), heat dissipation, noise and vibration reduction, and cleaning contaminants from gear meshing (cleaning function). Prevent corrosion, pitting, and surface metal tearing, isolate metal surfaces to prevent direct metal-to-metal contact. Three methods of changing transmission fluid are as follows: Loosen the drain screw 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 settled at the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: A smart circulation machine enables dynamic fluid exchange, filtering and cleaning sludge and impurities from the automatic transmission.
