자동변속기 DISENGAGEMENT 변속 성능 연구

For improving engagement shift performance, valve body orifice tuning, TMS control logic change and mounting characteristics change was done. And the backlash of power train was inspected. Optimized small orifice size gave good disengagement shift. D3-N shift control was more superior to DJ-N. Small gap and ridid mounting has absorbed jerking shock more effectively.
