Abstract
A power transmission utilizing only eleven gears and four shafts to obtain six forward speeds, three reverse speeds, and an 19-inch drop from input to output shafts. Optionally, there may be provided an inbuilt power-take-off and brake uniquely located with an 8-inch drop from the input shaft. A power transmission further expanded to obtain twelve forward speeds and six reverse speeds with addition of (1) a low-range planetary system, and (2) a direct clutch, each connectable between a journalled output gear to the output shaft.
