Abstract

A transmission for connecting a prime mover with a load, such as vehicle wheels, in which the transmission is of group construction with a primary group shiftable under load and at least one other group which is not shiftable under load. The group shiftable under load provides for at least two forward speeds and a reverse speed at the main output shaft of the transmission which supplies the power to the load.
