For GM / General Motors. DT-47678-A Service Fixture is used with DT-47678-10 Adapters to service Tremec transmissions, and by itself to service Aisin units. Unit repair on these transmissions must be done with the transmission vertical, especially snap ring removal and installation. If the unit is not held upright, components can bind, not allowing other components to seat properly, and making assembly very difficult. DT-47678-A mounts the transmission to J-03289-20 Bench Mount, and allows full service on the unit.
