Stupid clutches. Needed for the nutty A4WD mode, but don't offer a true 100% lockup when fully engaged in 4HI. Also no aftermarket support, which I found when I called around to see if anybody had gears to make a 4-to-1 low range. The NP231 normally comes with the same 2.7-to-1 as ours, but you can get that fixed easily.v7guy wrote:What's the problem with the stock transfer case?
