Correct me if I am wrong, but my understanding is that the torque converter basically only multiplies torque from a stop or when trying to accelerate hard in a high gear.

I remember reading somewhere that a torque converter needs at least a 500 RPM difference between input and output speed (slip) to multiply torque, so any less than that just wastes energy from my understanding.
