1. A method for controlling a vehicle transmission system having a clutch system, the method comprising:
generating a torque-pressure (T-P) gain deviation based on a transfer function (T-F) characteristic and a nominal (N-T-F) characteristic for the clutch system, wherein the T-F characteristic includes a set of torque values and a set of pressure values, and the N-T-F characteristic includes a set of nominal pressure values and a set of nominal torque values;
generating a pressure magnitude deviation based on the pressure values and nominal pressure values; and
issuing a notification indicating the T-F characteristic deviates from the N-T-F characteristic based on the T-P gain and pressure magnitude deviations to perform a corrective action related to the clutch system.
