Hi Everyone,

I've been trying to mathematically model a torque converter in MATLAB Simulink and have been having issues with some conceptual problems. The first one deals with negative torque going through a torque converter. Say we were to apply engine braking or regenerative braking via an engine/motor. Would there still be a torque multiplication? Can we even apply a negative torque through a torque converter or would the lock-up clutch need to be engaged?

Thanks!

How do most automatic transmissions handle low gear?
