Abstract

796,777. Change-speed control. GENERAL MOTORS CORPORATION. March 26, 1956 [April 29, 1955], No. 24727/57. Divided out of 796,774. Drawings to Specification. Class 80(2). The subject-matter is the same as that in the parent Specification, but the claims are directed mainly to the control system and in particular to the 4-2 timer valve 482 (see parent Specification), which, by controlling a by-pass to a restrictor 540 normally delaying actuation of one of the ratio clutches and brakes, momentarily establishes third gear ratio during a jump-step 4-2 downshift, thereby producing a smooth shift. Specifications 796,775 and 796,776 also are referred to.
