Abstract
A multi-speed transmission with a shift mechanism which selectively couples at least a forward and a reverse gear operatively positioned on a shaft. The shift mechanism is disposed entirely within the transmission housing and includes a shift key arranged for sliding movement of the key in the shaft. An improved neutral collar is positioned on the shaft between the forward and the reverse gears. The neutral collar has its widest cross section centrally located thereto. From this widest central cross section, the neutral collar profile tapers along the inside surface thereof to relatively narrow cross section at each end thereof.
