Abstract
Systems and methods are provided for controlling a transmission associated with a vehicle. The method includes receiving a neutral range selection for the transmission, and receiving a temperature and a pressure of a lubricant associated with the transmission. The method includes receiving a speed of an input shaft associated with the transmission, and determining, by a processor, based on the temperature and the speed of the input shaft, a pressure threshold value for the lubricant. The method includes outputting, by the processor, one or more control signals to command the transmission to a one clutch neutral state in which one clutch of a plurality of clutches associated with the transmission is engaged based on a comparison of the pressure threshold value to the pressure of the lubricant.
