In an automatic transmission according to the present invention, a coast brake cutoff valve is arranged between a range-pressure-producing manual valve and shift valves and, when changed over, selectively feeds oil to hydraulic engine brake servomotors. An engine brake solenoid valve is on/off controlled by a shifting output signal from a CPU, whereby the coast brake cutoff valve is selectively changed over. A lockout valve is arranged between the coast brake cutoff valve and the manual valve and is connected to one of shifting solenoid valves. The automatic transmission can therefore be operated without trouble even when an electrical problem occurs in the shifting solenoid valves and/or the engine brake solenoid valve.

Automatic transmission

A shift control system for an automatic transmission, comprising a shift unit for selecting by manipulating a shift lever an automatic shift mode, in which a gear stage is determined on the basis of a running state of a vehicle, and a manual shift mode in which a gear state is determined from an output signal based on the manipulation. The shift unit has a drive range capable of setting a plurality of forward gear stages and a plurality of range positions arrayed and includes: a first shift path for guiding the shift lever into the range positions; a second shift path intersecting the first shift path for guiding the shift lever; two third shift paths formed at the two end portions of the second shift path, the third shift paths having at their individual end portions gear stage positions for indicating the forward gear stages in the automatic shift mode and for guiding the shift lever; and a manual shift instructor for outputting a signal instructing a gear stage corresponding to the gear stage position when the shift lever is moved to the gear stage position. The shift control system comprises a gear stage setter for setting the gear stage which is instructed by the output signal of the manual shift instructor.
