Can different types of automotive transmission fluids be mixed?
Mismatch of friction coefficient leads to transmission failure: Different gearboxes have significantly different requirements for oil friction coefficient. For example, CVT gearbox relies on steel strip and cone wheel friction transmission, requiring specialized oil with low friction coefficient to prevent slipping; The AT gearbox relies on a hydraulic torque converter and clutch to operate, requiring a medium friction coefficient to ensure power transmission. If AT oil is added to the CVT gearbox, it will cause severe wear of the steel strip due to high friction coefficient; On the contrary, adding CVT oil to the AT gearbox may cause clutch slippage and poor power transmission.

What should be noted when checking and replacing the gearbox oil in a car?
The premise of inspection should be accurate: Oil temperature requirement: Most automatic transmissions (AT/DCT/CVT) need to heat the oil to 40 ℃ -60 ℃ (idle for 5-10 minutes without turning off the engine), at which point the oil is at normal working viscosity and the liquid level measurement is most accurate; The manual gearbox can be inspected for cold driving.

What are the symptoms of insufficient transmission oil in a car?
Transmission oil is the medium for power transmission and gear shifting execution. Insufficient oil can lead to insufficient hydraulic pressure (AT, DCT, CVT) or insufficient lubrication of gear meshing (MT). Manifesting as noticeable stuttering and impact during gear shifting, or requiring a delay of several seconds for power response after shifting, especially during low-speed upshifts.
