AUTOMATIC RANGE SHIFT ARRANGEMENT

摘要

An automatic range shift control system for automatically controlling range section (14) shifting in an otherwise manually shifted range type compound transmission (10) is provided. A sensor (100) senses a value indicative of vehicle ground speed and provides a signal (100A) which is compared to a reference value. If the signal is greater than the reference, an actuator (96) is urged to engage the high speed range ratio and if the signal is less than the reference, the actuator is urged to engage the low speed range ratio.
