Automatic Transmissions For Passenger Coaches 750381

Since the first passenger coaches were built in the early 1900's, coach manufacturers have sought better and better engine-transmission combinations and arrangements in order to improve performance, operation, and passenger convenience. As the coach industry entered the 1970's, it became increasingly obvious that a need existed for a new transmission to replace those of the old V-family that provided the bulk of the market for the past 40 years.Recognizing the need, Detroit Diesel Allison developed two new transmissions, the HT 740 and the V730, for the coming generation of coach applications. These two units permit a number of engine-transmission-axle arrangements and are adaptable to diesel and gas turbine engines. It is anticipated that these units will find wide usage in new coaches currently under development.
