If a transmission is in fail safe mode, will the Torque Converter apply?

When a transmission is in fail-safe mode, it is designed to limit functionality to prevent further damage or adverse operating conditions. In this mode, the system typically disables certain functions, including the application of the torque converter clutch. The main purpose of fail-safe mode is to ensure the vehicle can still operate, but in a limited capacity, often with reduced power and efficiency.

This means that the torque converter clutch, which helps improve fuel efficiency by locking the converter in direct drive, will not apply when the vehicle is in this mode. By not applying the torque converter, the system helps to avoid potential overheating or damage that could occur from malfunctioning components. Thus, the correct understanding of fail-safe mode is that it leads to the non-application of the torque converter.
