    摘要： A control system for executing an upshift from an off-going speed ratio to an on-coming speed ratio by controlling the release of the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio and by controlling the supply of the hydraulic pressure to the frictionally engaging element used for the on-coming speed ratio comprises first and second off-going pressure releasing valves 70 and 80, which release the hydraulic pressure of the frictionally engaging element used for the off-going speed ratio, and a linear solenoid valve 60, which controls the operation of the off-going pressure releasing valves. The linear solenoid valve 60 controls the operation of the off-going pressure releasing valves in correspondence to the throttle opening of the engine. In this case, the smaller the throttle opening of the engine, the earlier the timing for releasing the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio is set.

    摘要： An automatic transmission for a vehicle comprises a torque converter TC equipped with a lock-up clutch (4). This automatic transmission further comprises first to fourth speed clutches for a shift control executing a shift from an off-going speed ratio to an on-coming speed ratio by controlling the release of the hydraulic pressure from the off-going clutch and by controlling the supply of the hydraulic pressure to the on-coming clutch. A control system comprises first and second off-going pressure releasing valves (70,80), which release the hydraulic pressure from the off-going clutch during the shift, a lock-up control valve (40) and a lock-up timing valve (50), which control the engagement of the lock-up mechanism, and a linear solenoid valve (60), which supplies a control pressure to these valves and controls the operation of these valves.
