What is the model number of the transmission fluid level screw?

[LeBrianna]

The transmission filling screw is M20x1.5, and the drain screw and oil pan screw are of the same model, both being M14x1.5. The signs that indicate the need for transmission fluid replacement are: body shaking, gear shifting hesitation; the dashboard shows a transmission high-temperature warning; the car stalls; unusual noises occur. The methods for replacing transmission fluid are as follows: Unscrew the drain screw at the bottom of the transmission to drain the 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 replacing transmission fluid for a long time: 1. Damage to the transmission's gear shifting control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission valve body.
