する自動変速機の変速制御装置。[Scope of claim for utility model registration] By switching various shift valves, at least high, medium,
It has three types of gear shifting functions: a shift valve for switching between medium and low speeds, a relay valve that communicates the circuit with the circuit during medium and low speeds, and a shift valve for switching between medium and low speeds. A downshift valve is provided to communicate the circuit, and when downshifting from a high gear to a low gear in an automatic driving range, the switching pressure for low speed is transferred to the shift valve after passing through the middle gear via a relay valve and a downshift valve. In the automatic transmission, the manual range pressure generated in the manual range of the low gear is supplied to the communication switching side of the downshift valve, and the manual range pressure is supplied to the upstream side of the relay valve of the circuit. A speed change control device for an automatic transmission characterized by being installed on the side.
