Abstract
A method and system for regulating engagement of a torque converter clutch (TCC) in a vehicle incorporating a transmission that is driven by an engine through a torque converter includes determining a non-linear slip profile based on vehicle operating parameters, calculating an actual TCC slip, calculating a TCC ramp pressure based on the non-linear slip profile and the actual TCC slip and regulating a TCC engagement pressure based on the TCC ramp pressure.
