A method for automatically calibrating clutches (52, 54, R1- R4) within a transmission of a work vehicle, the method comprising: - determining whether a plurality of predetermined conditions are satisfied for performing a clutch calibration on a clutch (52, 54, R1- R4) of the transmission, wherein the plurality of predetermined conditions require that the work vehicle be in park and that a predetermined time period has elapsed since a previous clutch calibration was performed on the clutch; automatically initiating the clutch calibration without requiring operator input when the plurality of predetermined conditions are satisfied; and - performing the clutch calibration in order to calibrate the clutch wherein performing the clutch calibration comprises: - transmitting an initial current command to a clutch valve associated with the clutch to command a clutch pressure within the clutch; - determining an engagement condition of the clutch at the clutch pressure; - determining whether an adjustment of the initial current command is required based on the engagement condition of the clutch in order to obtain a final current command for the clutch calibration; - further comprising adjusting the initial current command up or down based on the engagement condition in order to obtain the final current command; and characterized in that a total current adjustment made between the initial current command and the final current command is limited to a predetermined maximum current change. - determining whether a plurality of predetermined conditions are satisfied for performing a clutch calibration on a clutch (52, 54, R1- R4) of the transmission, wherein the plurality of predetermined conditions require that the work vehicle be in park and that a predetermined time period has elapsed since a previous clutch calibration was performed on the clutch; automatically initiating the clutch calibration without requiring operator input when the plurality of predetermined conditions are satisfied; and - performing the clutch calibration in order to calibrate the clutch wherein performing the clutch calibration comprises: - transmitting an initial current command to a clutch valve associated with the clutch to command a clutch pressure within the clutch; - determining an engagement condition of the clutch at the clutch pressure; - determining whether an adjustment of the initial current command is required based on the engagement condition of the clutch in order to obtain a final current command for the clutch calibration; - further comprising adjusting the initial current command up or down based on the engagement condition in order to obtain the final current command; and - transmitting an initial current command to a clutch valve associated with the clutch to command a clutch pressure within the clutch; - determining an engagement condition of the clutch at the clutch pressure; - determining whether an adjustment of the initial current command is required based on the engagement condition of the clutch in order to obtain a final current command for the clutch calibration; - further comprising adjusting the initial current command up or down based on the engagement condition in order to obtain the final current command; and
