JUSTY ECVT – ATSG (Automatic Transmission Service Group)

The Subaru Justy ECVT transmission is a constantly variable transmission. Actually its a transmission with more than 1000 gear ratios.  Although this technology dates back to 1909 in motor vehicles its been improved with computer controlled technology. The Justy uses a carbon particle coupling in the place of the standard Torque converter. When the accelerator is depressed the carbon particles in the coupling between the engine and the transmission is energized which solidifies the coupling. The brushes that ride the coupling hub when worn can cause a slipping condition. This manual contains information on the teardown, assembly and trouble shooting of this unit.
