Abstract
A main transmission has a transfer gear attached to its output shaft. The transfer gear provides two wheel high speed drive, four wheel high speed drive, and four wheel low speed drive. A control system controls the main transmission according to a detected speed mode of the transfer gear. The control system uses an electrical detector for sensing the speed mode of the transfer gear.
