In Borg Warner automatic gearboxes you can easily instal the 'sprag' the wrong way round and lock the entire unit.
If the sprag is between the engine and the gearbox there would be no over run braking but changing manual gears would be easy if the throttle is lifted.
The unit pictured by flynfrog certainly looks like it has two clutches, one cetrifugal and one multi plated.
What unit is it?
