As far as how it works, I'm still confused. It seems to me that having a clutch physically lock front to rear would result in a clutch that would wear out quickly and would need to be a consumable and serviceable part. Perhaps that's why running the DCCD at 100% generates so much heat, and why you shouldn't do it except on loose surfaces, but I'm still not convinced that's the way it works.

I don't disagree with the braking thing, just the always-35/65-no-50/50-ever thing.
Clutch wear is minimized by three things I can think of:
- In Auto the ECU probably keeps it open as much as possible (but I don't know this for sure).
- As Dean mentions the speed difference is usually not much.
- These are wet clutches bathed in the lube that lubes the planetary gears (I assume). Synchronizers are basically wet clutches and last a long long time under more stressful conditions. LSD clutches are even more similar.
