I diddn't got that Question in Detail, i'm afraid.
The 4EAT exists in two diff. Versions: With VDC and Without.
The Version Without VDC uses a wet Clutch (Running in Oil) to engage the rear Wheels.
This means, that the rear axle can get up to 100% of the Torque.
At low speeds and high power demand the rear Axle usually gets engaged, up to a given Amount. (Varies over the Models, and depends on ext. Influences)
At Highway speeds, it's a 100% fwd.
The VTD-eqipped 4eat has a diff. gear, which allwasy distributes torque to the rear, like the 5MT does.
Different vorm the 5MT it's an electronic controlled Cluth in parrallel.
In Terms of Handling on Concrete and Tar, is think of the VTD and the 5MT to be superior, on mud and Gravel the 4EAT will give better traction.
