Abstract:
A method comprises operating an engine of a vehicle to provide output torque to an input of a torque converter, determining whether the engine is in a cold start condition, fixing an input shaft of a transmission when the engine is in the cold start condition, and coupling the input shaft of the transmission to an output of the torque converter. A control module comprises a combustion control module that operates an engine of a vehicle to provide output torque to an input of a torque converter, a NPD module that determines whether the engine is in a cold start condition, and a transmission control module that fixes an input shaft of a transmission when the engine is in the cold start condition, wherein the input shaft of the transmission is in communication with an output of the torque converter.
