Document Type and Number:
Japanese Patent JP2646870
Kind Code:
B2
Abstract:
A fluid pressure circuit for an automatic transmission allows a single accumulator to selectively provide a plurality of pressure adjustment characteristics. The fluid pressure circuit includes a directional control valve responsive to a value of a reverse clutch pressure PR relative to a threshold pressure PCH, to connect either of a high-clutch pressure PH or the reverse clutch pressure PR with the accumulator such that the pressure adjustment characteristics for each are respectively different for eliminating a shifting time lag in the automatic transmission.
