These transfer cases aren't that smart, there aren't any electronics involved in the transfer case "kicking in". This design isStepping into the “academics” of how the TOD works, curious what triggers the clutches engagement and its “percentage”. It would seem to me that TC would be the primary trigger for engagement, but “100%” clutch engagement would make me think you would at least get some feeing of the binding on the circumstances we were mentioning before (slightly wet roads, right hand turn and stepping on it). Curious if the system acknowledges wheel speed sensors in the front and the TC associated with the front to engage up to “100%”. It makes me think that anything full dirt or snow would be better served with 4H to ensure full front axle engagement from the second you may be losing traction.
using the equivalent of a limited slip unit like what is in a differential. It will transfer the power 50/50 up until the clutches slip thus allowing a torque bias. in 4auto, the shift mechanism loads the spring against the clutch a small amount thus allowing the clutches to slip at a lower torque. When shifted into 4hi, the shift mechanism increases the spring load thus increasing the clutch holding power.
The Gen 2 cases actually have a locking pawl that that engages when in 4hi/4lo. The gen 2 cases are preferred for those who intend high horsepower, rock crawling, or generally heavy offroad use as @Primez pointed out.
