ABSTRACT:
A system comprises a slip module and a gas temperature module. The slip module adjusts slipping of a clutch of a torque converter based on a first slip value before a cylinder of an engine is deactivated. The gas temperature module determines a temperature of a gas within the cylinder after the cylinder is deactivated. The slip module determines a second slip value based on the temperature of the gas and adjusts the slipping of the clutch based on the second slip value, wherein the second slip value is less than the first slip value.
