A vehicle may include a controller configured to, in response to an accelerator pedal release and an expected regenerative braking event, increase an engagement pressure of a torque converter clutch prior to occurrence of the event to a threshold that is based on a regenerative braking torque estimate associated with the event such that during the event, the clutch transfers more torque than the converter. The regenerative braking torque estimate may be based on a difference between an average road grade and a current road grade. The regenerative braking torque estimate may be based on a headway range and a rate of change thereof. The regenerative braking torque estimate may be based on a predicted deceleration rate.
