Abstract
A gear shifter for automatic transmissions having a true ratchet mode for operating between the drive gears and a gate mode optionally usable for the drive gears. Only gate mode accesses park and reverse gears. The invention provides a floating pawl at the ends of two links in a three member, four pivot point linkage. This linkage provides the advantages that the operating handle is always engaged and yet permits easy change-over from one mode to the other.
