A transmission and control method are disclosed which ensure proper stroke pressure and minimize torque transients during a shift event. The transmission includes a clutch having a torque capacity based on a fluid pressure, a torque sensor adapted to measure a torque value that varies in relationship to the torque capacity, and a controller. The method includes varying the fluid pressure around a predetermined value, measuring a resulting torque difference with the torque sensor, and adjusting a clutch control parameter if the resulting torque difference is less than a threshold value.
A method for controlling a transmission comprising:
A method for controlling a transmission comprising:
A computer-program product embodied in a non-transitory computer readable medium that is programmed for controlling a transmission shift event and comprising instructions for:
