Abstract

A multi-speed transmission having an H-pattern shift has parallel output and intermediate shafts. An input shaft is connected to the intermediate shaft which has a gear connected to a reverse gear on the output shaft. The output shaft has first, second, and third forward gears, the reverse and forward gears having notches. The intermediate shaft has three gears connected to the forward gears. The output shaft has slots under the forward and reverse gears, the collars being movable in either direction from a neutral position. One slot has a key connected to one collar and extends toward the reverse gear engaging a notch therein in one position, the key having a portion extending toward the forward gears engaging a notch in the first gear in the other position of the collar. The other collar surrounds the portion of the key. Another slot has another key connected to the other collar, extending under the first gear and into a space between the second and third gears in the neutral position, engages a notch in the second gear in the first position, and engages a notch in the third gear in the second position of the other collar. A shift lever has an H-pattern movement. Links are connec…
