Shift rod position indication system
First Claim
1. A shift rod position indicator system for an automotive vehicle transmission having at least one gear set operated by a shift rod, comprising:
- a plurality of sensors fixed to a housing of the transmission in spaced relation to each other; and
actuating means moved by the shift rod for actuating the sensors;
wherein said sensors and actuating means are arranged such that a first electrical signal is produced when the shift rod is operated so as to partially engage the gear set, and a second electrical signal is produced when the shift rod is operated so as to fully engage the gear set.

Abstract
A shift rod position indicator system for an automotive vehicle transmission includes a plurality of position sensors fixed to the housing of the transmission and actuating means moved by shift rods in proximity to the sensors which generate an electrical signal according to the displacement of the shift rod during the shifting operation, the electrical signal corresponding with initial and full engagement of the gear, the signal being maintained over the extent of gear engagement to provide an electronic control circuit with information so as to permit the synchronized operation of clutches to effect a semi-automatic gear change.
