Abstract
A torque converter clutch control system is provided. The system includes: a mode determination module that selects one of a lock low slip regulation mode and a hard lock mode based on a lock request; and a pressure control module that regulates pressure to the torque converter during the lock low slip regulation mode such that a target slip is maintained and commands a maximum pressure to the torque converter during the hard lock mode to prevent slip.
