Does Changing Transmission Fluid Affect Performance?

[DiFinley]

Changing transmission fluid does not affect performance. The signs that indicate the need for transmission fluid replacement are: body vibration, gear shifting hesitation; the dashboard displays a transmission overheating warning; the car stalls; unusual noises occur. The methods for changing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid before refilling. 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 from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. The hazards of not changing transmission fluid for a long time include: 1. Damage to the transmission's gear shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affecting the normal operation of the transmission, leading to damage to the transmission valve body.
