Automatic transmission working fluid pressure control apparatus |
摘要 |
A fluid pressure control apparatus for use with an automatic transmission having a hydraulic circuit connected to supply a fluid pressure so as to operate selected ones of friction elements in the engaged position and release the fluid pressure so as to operate selected ones of the friction elements in the disengaged positions. The control apparatus controls the fluid pressure to the friction elements according to a shift from a current gear position to a target gear position. The fluid pressure is applied temporarily to disengaged ones of the friction elements so as to exhaust air from the hydraulic circuit.
