Abstract
A method is provided for controlling engine torque from a vehicle engine to an electronically controlled transmission in response to predetermined conditions existing in the transmission. The method includes the steps of saving in memory data corresponding to a spark advance and fuel flow setting, detecting whether an upshift or downshift is in process, determining if the upshift or downshift has just started if an upshift or downshift is detected, variably adjusting the spark advance setting of the engine in accordance with a detected upshift or downshift if the upshift or downshift has just started, decrementing the amount of fuel flow to the engine during adjustment of the spark advance, and returning both the fuel flow and spark advance to its original setting.
