<p>An auxiliary parking release system of an automatic transmission is provided to operate a select lever by using oil pressure of a brake as auxiliary operating pressure. A connective member(36) for operating a shift cable(34) is fixed to a hinge part(32) of a select lever(30) of an automatic transmission by using a hinge. A free end part is connected to the shaft cable. An oil pressure cylinder(38) is arranged at the free end part of the connective member in order to be extended in R, N, and D range directions. The oil pressure cylinder is connected to an oil pressure line of a brake system. A two-way solenoid valve(40) is arranged on a path for connecting the oil pressure cylinder and the brake system to each other. The two-way solenoid valve is controlled by using an engine control unit.</p> |
