A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The second neutral has more engaged clutches than the first neutral. A vehicle controller is programmed to, in response to a request to shift from the first to the second neutral and a failed-on clutch being detected, inhibit the shift to remain in the first neutral.

The first neutral has more engaged clutches than the second. A controller is programmed to, in response to a request to shift from a drive gear to the first neutral and a clutch of the drive gear being failed-on, shift to the second neutral.

A control apparatus of an automatic transmission connected to an internal combustion engine of a vehicle includes a determination unit configured to determine an operation state of a hydraulic oil temperature sensor based on comparison between a threshold and a difference between a hydraulic oil temperature of the automatic transmission and a cooling water temperature of the internal combustion engine. When the operation state of the hydraulic oil temperature sensor is determined as normal by the comparison with the threshold, the determination unit further determines the operation state of the hydraulic oil temperature sensor based on an operation state of an oil pressure sensor determined using the hydraulic oil temperature, an oil pressure of hydraulic oil, and a rotation speed.

A control system for a continuously variable transmission (CVT) is provided. The control system includes a shift mode switch, an actuator and a controller. The shift mode switch is selectable between a plurality of modes. The actuator is in operational communication with the CVT to selectively override normal shifting characteristics of the CVT. The controller is in communication with the shift mode switch. The controller is configured to control the actuator to selectively override the normal shifting characteristics of the CVT based at least in part on a select mode configuration selected by the shift mode switch.

A hybrid controller unit includes a detection module, a gear-hold module, a gear-skip module, and an optimizing module. The detection module is structured to detect a deceleration event. The gear-hold module is structured to determine whether a certain gear of a transmission should be maintained for a certain period of time in order to optimize power regeneration during the deceleration event. The gear-hold module is also structured to generate a gear-hold request. The gear-skip module is structured to determine whether the transmission should skip a gear in order to optimize power regeneration during the deceleration event. The gear-skip module is also structured to generate a gear-skip request. The optimizing module is structured to receive the gear-hold request and the gear-skip request and generate a transmission command to be sent to a transmission control unit for actuation.

A control method for controlling a transmission of a vehicle, the method comprising: receiving at least one measurement relating to a hydraulic lag of a continuously variable valve lift system that occurs in a cold condition, the continuously variable valve lift system being associated with an engine of the vehicle; determining, based on the at least one measurement relating to the hydraulic lag, an engine speed threshold above which engine power output is impaired as a result of the hydraulic lag; monitoring the engine speed; and generating an alert if the engine speed exceeds the engine speed threshold.
