What are the symptoms of water ingress in a CVT transmission?
1 Answers
Introduction to symptoms of water ingress in a CVT transmission: 1. Mild water ingress: Some screws in the transmission may rust. 2. Moderate water ingress: White deposits appear in the oil pan. When oil mixes with water, it forms a white emulsion that adheres to the oil pan. The presence of such deposits indicates moderate water ingress in the transmission. 3. Severe water ingress: Can be determined by the color and viscosity of the transmission fluid. Maintenance methods for automatic transmissions: 1. Use the specified transmission fluid for power transmission: Do not opt for cheaper or more convenient manual transmission fluid, as it can cause severe burning of clutches and brakes. 2. In addition to using the specified fluid: Ensure the correct type of gearbox oil is used, otherwise issues like clutch slippage and hot gear jumping may occur. 3. Strictly control the amount of automatic transmission fluid added: The ATF fluid level must be between the bottom of the planetary gears and the top of the control valve body. If the fluid level is too high, the planetary gears may churn the fluid, causing foaming and potential leakage during driving. If the fluid level is too low, clutches and brakes are prone to slipping.
