Newbie here so please hold your fire. First Jeep on the way soon. I‘m watching videos about how to shift a Wrangler JL, but shifting the 392 is apparently different than the other JL’s. Here’s what I think to be true for the 392 transfer case:
4High Auto = gear for normal everyday driving on smooth hard surfaces
4High Part Time = gear for temporary 4 wheel driving. Not to be used all the time as could damage drive train.
N = neutral used for being towed
4Low = gear for slow rock crawling, etc..
Where my confusion comes in is reading the online owners manual for the 392 special features. In part it says, quote:
“This transfer case is designed to be driven in the four-wheel drive position (4H AUTO) for normal street and highway conditions on dry hard surfaced roads.
For variable driving conditions, the 4H AUTO mode can be used. In this mode, the front axle is engaged, but the vehicle's power is sent to the rear wheels. Four-wheel drive will be automatically engaged when the vehicle senses a loss of traction.
In the event that additional traction is required, the transfer case 4H AUTO and 4L positions can be used to lock the front and rear driveshafts together, forcing the front and rear wheels to rotate at the same speed. The 4H AUTO and 4L positions are intended for loose, slippery road surfaces only and not intended for normal driving. Driving in the 4H AUTO and 4L positions on hard-surfaced roads will cause increased tire wear and damage to the driveline components.”
The last two sentences basically state 4High Auto must not be used for daily driving. But that contradicts what I previously learned about 4High Auto and that being used for daily driving on hard surfaces.
Youtube has approximately ZERO videos on how to use the 392 Wrangler specific transfer case.
Can anyone help me solve this contradiction with 4High Auto?
