Abstract:
A method for an automatic transmission includes measuring torque of a component of the transmission using a torque sensor in communication with the component. The torque of the component is estimated from information other than the measured torque. The measured torque is rejected from being used in a control operation of the transmission if the difference between the measured torque and the estimated torque is greater than a selected threshold.
