What happen if the torque converter fails?

Transmission Issues: A faulty torque converter can lead to transmission problems. It won't be able to effectively transfer power from the engine to the transmission, resulting in erratic gear shifting, loss of power, or even transmission failure.

Overheating: Due to the lack of proper fluid circulation, the torque converter can overheat, causing damage to its internal components and potentially leading to transmission failure.

Stalling: If the torque converter completely fails, it may cause the vehicle to stall while driving, especially when coming to a stop or slowing down.

Engine Damage: In severe cases, a failed torque converter can cause excessive wear and tear on the engine, as it struggles to overcome the resistance of the faulty torque converter.

Reduced Fuel Efficiency: A malfunctioning torque converter can affect fuel efficiency as the engine has to work harder to overcome the problems caused by the faulty converter.

Unusual Noises: A failing torque converter may produce unusual noises, such as grinding, whining, or humming, indicating internal damage.

Loss of Power: The vehicle may experience a loss of power and acceleration due to the torque converter's inability to transfer power effectively.

It's important to address a faulty torque converter promptly to prevent further damage to the transmission and other components of the drivetrain. If you suspect issues with the torque converter, it is advisable to consult a professional mechanic for diagnosis and repair.
