728,498. Change-speed gear. GENERAL MOTORS CORPORATION. June 20, 1952 [July 5, 1951], No. 5667/54. Divided out of 728,461. Drawings to Specification. Class 80 (2). The description is an abridged version of that of Specification 728,461, but the claims are directed towards the timing valve 400 (see abridgment of Specification 728,461) which, during a 3-2 kickdown shift, interacts with the double-transition valve to prevent full release of the direct-drive clutch of the rear unit until that of the front unit is first engaged. Specification 522,881 is referred to. |
