Symptoms of water contamination in transmission fluid are as follows: 1. Mild contamination: Partial rusting of screws inside the transmission. 2. Moderate contamination: White sediment appears in the oil pan. When oil mixes with water, it produces a white emulsion that adheres to the oil pan. The presence of such sediment indicates moderate water contamination in the transmission. 3. Severe contamination: Can be determined by the color and viscosity of the transmission fluid. Water entering an automatic transmission will corrode the steel screws inside, requiring prompt transmission inspection and repair. Severe cases may lead to significant transmission damage.

Should I schedule the driving test (Subject 3) first or practice driving first?

It's better to schedule the Subject 3 test first and then practice driving, which is also the common practice at driving schools. Subject 3 practice tips: When practicing for Subject 3, try to avoid using the half-clutch technique. Coordinate the accelerator and clutch properly - they shouldn't be pressed simultaneously. Before shifting gears, release the accelerator first and then press the clutch. After shifting, release the clutch before pressing the accelerator. Gear shifting movements should be coordinated and not too forceful, as excessive force with the right hand may cause the steering wheel (controlled by the left hand) to deviate. Subject 3 scheduling tips: The current Subject 3 test scheduling system operates automatically, and neither local vehicle management offices nor driving schools can manually intervene. Therefore, choosing the "system allocation mode" can to some extent improve the success rate of scheduling a test, but the specific test session and time won't be fixed. Try to avoid choosing test centers that show as crowded, and it's recommended to select some more remote test centers.
