ABSTRACT:
A hydraulic control system for an automatic transmission of multiple clutch type (in FIG. 1), comprising an R cut valve 80 (and a 2-R sequence valve 70) whose positions are shifted in interlocking with the operations of dog clutches D.sub.2 (D.sub.r), and which control the supply of working oil to hydraulic actuators S.sub.r (S.sub.2) corresponding to the other dog clutches D.sub.r (D.sub.2) mounted on an identical one of power transmission shafts, so as to prohibit the engagement of the other dog clutches D.sub.r (D.sub.2), in a state in which the dog clutches D.sub.2 (D.sub.r) are engaged with speed change gears for the first or fourth speed stage (the reverse gear stage). Thus, even when the specified dog clutches D.sub.2 and D.sub.r are unintentionally engaged due to the fails thereof or the response delay of the hydraulic control system, the circulation of power is prevented from taking place.
