4WD Auto is awesome!! I have no use for it in the summer but winter??!! It’s fantastic…I don’t need to keep flipping between 2/4hi since the truck does the job for me really well. It’s such a luxury/worry free experience knowing the truck will engage itself in 4WD when you hit a light, or it senses slippage!
It's mostly a gimmick. First the abs needs to detect slippage so the vehicle is already slipping by the time pumps starting pumping pressure into the transfer case.. Usually the slippage is just momentary so by the time it's pumped up it's then receiving signals to release the pressure. Mechanical limited slip is vastly superior in these sporadic situations. If it's that slippery just put the unit in 4WD HI.
4wd auto is for ppl too clueless to operate the transfer case manually. It certainly is not a substitute for AWD.
Nope…you are assuming 4WD auto has not been modernized.
The current system system uses many other inputs, including if your wipers are on or off but really the best part is having the 4WD come on automatic every time the truck stops, so off a slippery surface - very common at lights - you take off in 4WD instead of slipping in 2WD, the going for the 4WD switch and waiting a few seconds for it to kick in, super annoying.
But under rain as well, the 4WD system will turn the front end during driving in many conditions - e.g. it’s raining, wipers are on at position 1, and you attempt to pass somebody, boom 4WD is activated…
It works marvellously, doesn’t bind and doesn’t really affect gas mileage.
