The 4EAT split the power front/rear 90/10 until slip was detected. Then through electronically controlled clutch packs, it could vary the power up to 40/60 I *think*. Anywayz, don't quote me on the numbers, but under most conditions, the transmission behaved as FWD with the majority of the power being trasmitted to the front.
Boy, alot of newbies posted incorrect info initially on this post! Isn't this in a FAQ somewhere and shouldn't this be in the transmission section of the board?
