I know how a wet clutch works. As the discs spin faster, this generates heat, which thickens the lubricant (goo!) and pushes all the discs together. So, even when these discs are locked together because of the heat from the lubricant, this still allows for slippage between the front and rear axles. In 4LOW, the drive lines are locked together, so there must be some electronic algorithm that locks the clutch discs, which overrides their normal operation. I'm new to the forum and new to this drive train, so all of this is probably a rehash to those who have been here for the past 3 years. I've been walking around the kitchen for the last hour trying to figure out how this works! My head is going to explode.
According to my 784 page Owner's Manual, driving in 4LOW on dry, hard surfaces may cause increased tire wear and damage to driveline components. Thus, there is NO allowance for slippage between the front and rear axles! This is your dead giveaway!
