Power transmission

A power transmission comprising:

• an input shaft;
• an output shaft;
• first and second countershafts spaced equidistant from and parallel with said input shaft and said output shaft;
• first clutch and gear means for selectively providing a first ratio between said input shaft and said first countershaft;
• second clutch and gear means for providing a second ratio between said input shaft and said second countershaft having a ratio numerical different from said first ratio;
• first and second ratio gear means including a common gear on said output shaft and equal size gears on respective countershafts and being selectively operable with said first and second ratio between said input shaft and said countershafts to establish distinct drive ratios between said input shaft and said output shaft.

A power transmission comprising:

• an input shaft;
• a pair of countershafts;
• an output shaft;
• a first gear and clutch means selectively connectable between said input shaft and one of said countershafts to provide a first ratio therebetween;
• a second gear and clutch means selectively connectable between said input shaft and said other of said countershafts to provide a second ratio numerically different from the first ratio;
• first output gear means drivingly connected with said output shaft;
• first and second equal diameter ratio gear means connectable with respective ones of the countershafts and meshing with the first output gear means and cooperating with the first and second gear and clutch means to selectively establish two distinct drive ratios between said input and said output shafts.
