Vehicles, transmissions, and methods of dampening oscillations at an output shaft of a transmission are disclosed. A vehicle includes a chassis, a plurality of wheels coupled to the chassis, and a powertrain mounted to the chassis that includes a transmission. The transmission includes an input shaft to receive torque from a drive unit, an output shaft to transmit torque to a load, at least one torque-transmitting mechanism coupled between the input shaft and the output shaft, and a control system having an output speed sensor to provide an input signal indicative of a rotational speed of the output shaft and a controller communicatively coupled to the output speed sensor.

An apparatus for determining a deterioration of a NOsensor response rate in an internal combustion engine system includes an engine control module configured to stop fueling to an internal combustion engine during motoring of the internal combustion engine. The apparatus also includes a signal monitoring module configured to monitor a NOsensor signal after the engine control module stops fueling to the internal combustion engine during motoring of the engine and store NOsensor signal data corresponding to the monitored NOsensor signal. Additionally, the apparatus includes a time constant module that is configured to determine a time constant of the NOsensor response after the engine control module stops fueling. The apparatus further includes a response rate deterioration module configured to determine a response rate deterioration value of the NOsensor based at least partially on the determined time constant.
