What are the symptoms of a torque converter failure in an automatic transmission?

There are many manifestations of transmission failure issues, such as transmission noise, transmission slippage, transmission oil leakage, etc., which need to be addressed based on the actual situation. Details of the fault causes are as follows: Transmission slippage: While driving, when accelerating, you can hear the engine racing. Transmission oil leakage: Oil leakage can lead to insufficient lubrication inside the transmission. Transmission jerking: The impact, vibration, and jerking sensation during gear shifting are relatively strong. Transmission noise: When the car is idling, driving, or under high-load driving conditions, abnormal noises or even loud noises from the transmission can be heard.
Last time I was driving, I noticed it was particularly difficult to accelerate. Even when I floored the gas pedal, the speed wouldn't increase—it felt like something was holding the car back. During takeoff, the engine RPM kept climbing with an extremely loud noise, but the car just moved sluggishly. When shifting gears, I could clearly feel the car shaking, especially when starting from a red light—the entire steering wheel vibrated. The fuel consumption increased alarmingly, burning 20% more gas for no apparent reason. On the highway, it was even worse: once I hit 50 mph, a buzzing sound came from the transmission area. The temperature gauge showed abnormally high transmission fluid temperature, forcing me to take breaks every half hour.
