摘要

A pneumatic control system for a range type compound transmission (10) is provided allowing preselection of a range section (14) shift by a range shift selector mechanism (98) and including an exhaust conduit control valve (118) which will prevent exhausting of one of the range actuator cylinder portions (120R, 120L) to atmosphere until the main transmission section (12) is shifted to a neutral condition.
