Transmission Fluid Change: Flush Machine or Gravity Drain?

[GrahamAnn]

Both flush machine and gravity drain methods can be used for transmission fluid replacement. The transmission fluid change procedure is as follows: 1. After loosening the tightening nut at the bottom of the oil pan, the transmission fluid will automatically flow out from the drain hole; 2. Connect the transmission and the flush machine through pipeline interfaces to push out old fluid with new fluid; 3. Remove the oil pan for fluid replacement. The purposes of transmission fluid replacement are: to maintain cleanliness of the gear system, and to lubricate transmission components while extending their service life. Precursors for transmission fluid replacement include: 1. Vehicle vibration and gearshift hesitation; 2. Transmission overheating warning appears on the dashboard; 3. Engine stalling; 4. Abnormal noises occur.
