What Are the Common Faults of a Transmission?

[Frances]

When pressing the accelerator pedal during vehicle startup, the engine speed increases rapidly, but the vehicle speed rises slowly. During driving, when pressing the accelerator pedal to accelerate, the engine speed increases, but the vehicle speed does not rise quickly. The vehicle operates normally on flat roads but lacks power when going uphill, accompanied by abnormally high engine speed. Here are additional details: Troubleshooting: Automatic transmission fluid level is too low; Automatic transmission fluid level is too high, generating excessive bubbles when vigorously agitated by the planetary gear mechanism; Excessive wear or burning of clutch or brake friction plates and brake bands; Excessive wear of the oil pump or leakage in the main oil circuit, resulting in low oil pressure; Slippage of the one-way overrunning clutch; Damage to the piston seal rings of the clutch or brake, causing oil leakage.
