Abstract:
A system for calibrating a transmission includes a slip generation module, a volume determination module, and a calibration control module. The slip generation module generates transmission slip. The volume determination module, after the transmission slip has been generated, applies a torque converter clutch (TCC) and determines a volume of the TCC based on a period for the TCC to fill with hydraulic fluid. The calibration control module generates a calibrated volume based on the determined volume and calibrates a control module based on the calibrated volume, wherein the control module controls the transmission.
