Abstract
A compound change gear semi-blocked transmission (10) of the splitter type is provided. The transmission comprises a multi-speed main section (12) connected in series with an multi-speed auxiliary section (14). The main section utilizes manually engaged, non-blocked, nonsynchronized jaw clutch assemblies (56, 58, 60) while the auxiliary section utilizes resiliently shifted blocked jaw clutch assemblies (114, 116, 118, 120). The blocked jaw clutch assemblies are provided with ramps (176, 178, 180, 182) which will cause unblocking during a clutching operation if the main section is not engaged.
