Learning method for oncoming clutch fill level and volume
A method for adaptively learning clutch volumes and fill level to compensate for build tolerances and clutch wear includes increasing a fill level of a clutch during an oncoming fill phase of a clutch to clutch transmission. A state of a regulator valve of the clutch to clutch transmission is monitored during the oncoming fill phase. Fill level of the clutch is adjusted before a next shift based on whether the regulator valve switches from a regulating state to a full feed state before elapse of a valid shift time.
