Abstract
A fluid pressure actuated auxiliary transmission section (14) shift control system (3230/270)/method is provided which includes a control member (246) to prevent auxiliary section synchronized clutch (92, 128) damage if the main transmission section (12) is engaged during an auxiliary section shift. A range synchronizer protection valve (246) is effective to exhaust at least the high speed ratio chamber (224) of the piston actuator (220) whenever a main section engaged condition is sensed.
