ABSTRACT:
An in-line shift mechanism for an automotive automatic transmission having the dual capability of permitting selective shifting directly into any one of plural drive positions, a neutral position, a reverse position or a park position, and also of only sequential shifting through the three drive positions in either direction while requiring momentary release of the shifting lever between adjacent drive positions. The shift lever is pivotally mounted for forward and rearward movement as well as perpendicular (usually generally vertical) movement relative to the pivot axis of the lever. A cam surface is provided on the mounting bracket for engagement with a pin carried by the shift lever to require vertical displacement of the shift lever to move from park position into reverse position and another vertical displacement to move from reverse position to any of the three drive positions or neutral. A pawl and detent plate are mounted respectively on the shift lever and the mounting bracket to require successive shifting through the three drive positions while the shift lever is in its lowermost vertical position.
