What are the symptoms of clutch slippage in an automatic transmission?
2 Answers
Symptoms of clutch slippage in an automatic transmission include: 1. When pressing the accelerator pedal during startup, the engine speed increases quickly but the vehicle speed rises slowly; 2. During driving, when pressing the accelerator pedal to accelerate, the engine speed increases but the vehicle speed does not improve; 3. The engine speed is very high, and the vehicle runs normally on flat roads, but lacks power when going uphill or under heavy load; 4. Increased fuel consumption. Causes of clutch slippage in an automatic transmission: 1. Insufficient or dirty transmission fluid, leading to incomplete clutch engagement and disengagement; 2. Wear and burning of the clutch disc due to prolonged use, preventing the clutch from being tightly pressed; 3. Excessive wear of the oil pump or leakage in the main oil circuit, resulting in low oil pressure; 4. Damage to the piston seal ring of the clutch or brake, causing oil leakage.
The symptoms of automatic transmission clutch slippage are quite obvious. I remember once driving a friend's car where the engine RPM suddenly surged during acceleration, but the car accelerated very slowly, with little response even when the gas pedal was pressed hard—it felt like the engine was revving in neutral. Starting from a stop was especially bad; when the light turned green and I pressed the gas, the car hesitated for a few seconds before moving, as if the power wasn't reaching the wheels. Climbing hills was even more troublesome—the engine kept roaring, but the car barely moved, sometimes accompanied by slight shaking or metal grinding noises, which was quite alarming. Over time, fuel consumption skyrocketed because energy was wasted on the engine. This situation is likely due to worn clutch plates or issues with the hydraulic system. I recommend taking it to a repair shop immediately for inspection to avoid further damage to more components and ensure driving safety.
