Torque Reduction Control

This control improves the shift quality due to sending torque reduction request signal from TCM to ECM and cutting engine torque increase of shift at N-D shift, N-R shift and 1 infine 2 infine 3 infine 4 infine 5.

If accelerator pedal is depressed rapidly, this control establishes the upper limit value of engine torque and avoids engine flare at 2 infine 3, 3 infine 4 and 4 infine 2 of clutch to clutch shift.
