Symptoms of Too Much or Too Little Transmission Fluid

[DiPatrick]

When there is too much transmission fluid, starting the vehicle requires the gears to overcome the resistance of the fluid, leading to power loss. Additionally, the agitation of the gears causes the fluid to foam, introducing air into the fluid passages and reaching the clutch. When shifting into D gear, the presence of air between the clutch plates prevents them from pressing tightly, resulting in clutch slippage. When the transmission fluid is insufficient, acceleration power is reduced, and internal transmission components may overheat and fail. Signs that transmission fluid needs replacement include: vehicle shaking, rough gear shifting; transmission overheating warning on the dashboard; engine stalling; and unusual noises. Methods for replacing 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 to drain and refill the fluid: This method is more thorough than the previous one, as it allows for the removal of debris from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: A smart circulation machine enables dynamic fluid replacement, filtering and cleaning sludge and impurities from the automatic transmission. Long-term failure to replace transmission fluid can lead to: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impaired transmission operation, resulting in damage to the transmission valve body.
