摘要	A kick down shift control apparatus of an automatic transmission of a vehicle comprising: vehicle running state sensing means for checking a running state of the vehicle; engine control means for controlling engine outputs in response to a signal sensed by the vehicle running state sensing means and outputting information on the temperature of intake air and the operational state of an air conditioner; shift control means for outputting a control signal to correct the pressure of transmission oil according to the temperature of absorbed air and the operational state of the air conditioner input from the engine control means, if conditions for a kick down shift are met with reception of the signal checked by the vehicle running state sensing means; and driving means for controlling the oil pressure discharged out by the oil pump according to the control signal output from the shift control means and performing a shift by providing the oil pressure for a relevant friction factor, thus relieving an shifting shock that generates at the time of a kick down shift while the output of the engine is reduced due to a high temperature of intake air supplying to the engine or operations of the air conditioner.
