<p>A manual valve of a hydraulic control system for use in an automatic transmission is provided to reduce gearshift impact by mechanically controlling a discharge flow using a fluid discharge controller according to temperature and viscosity of an automatic transmission fluid. A valve body is provided with a discharge channel comprised of an inlet hole(14) and an outlet hole(12). The inlet hole and the outlet hole are communicated with a D range port at an N range in order to discharge an automatic transmission fluid supplied from a D range when the D range is shifted to the N range. A fluid discharge controller controls a discharge flow of the automatic transmission fluid to two channels according to a discharge pressure of the outlet hole.</p> |
