Abstract The variable speed control equipment of automatic speed changing machine formed from forward and backward selective hydraulic servomechanism capable of actuating dogtooth clutch and several clutches possesses first-fifth on-off solenoid valves and first-third linear solenoid valves. It utilizes the pipeline pressure discharged by these valves to control the action of forward and backward selective hydraulic servomechanism and first-fifth speed changing valves, and control the action of every clutch. It also utilizes the hydraulic switch to detect the selected D drive range, and can detect the action instrution signal of the solenoid valve, if said action instruction signal is the signal of any state being in D drive range, said solenoid valve based on said action instruction signal can be acted.
