What are the symptoms of a torque converter failure?

[MacDante]

The symptoms of a torque converter failure are as follows: 1. No working fluid in the torque converter: Since there is no mechanical connection between the pump impeller and the turbine in the torque converter, power is transmitted through the fluid as a medium. Without fluid, power naturally cannot be transmitted. 2. Loose or stuck connection between the turbine and the turbine shaft: Cracks at the welding point between the turbine blades and the turbine spline hub, damage to the spline connection between the spline hub and the turbine shaft, or bearing failure inside the torque converter can cause the turbine to become loose or stuck to the turbine shaft, preventing power from being output through the turbine. 3. White smoke: The engine operates normally, but fuel consumption increases. The transmission and transmission oil temperature rise significantly, and the transmission oil is prone to deterioration. In severe cases, white smoke may emerge from the oil filler port.
