JLU Wrangler Auto 4WD

[2mnycars]

We often have intermittent snow and intermittent slippery roads.

What is the maximum speed that auto 4wd can be used at? We are skiers. It would be great to put the Jeep in Auto 4Hi and drive.

I’ve driven at highway speed with no issues. I don’t believe the auto 4wd has a speed restriction.

Thanks Dave!

There is a recommended speed limit on shifting between modes (consult the manual for your trim level/transfer case), but not the speed you can drive at in that mode. There's nothing wrong with leaving it in 4A, but being in the GTA, I recommend you use 4HI whenever you're off dry pavement and in those potentially slippery conditions. That's part of the fun of driving a Wrangler!

I leave it in 4 Auto year round. I like how it feels and gets the power down in combo with the limited slip differential!

OP, I don’t believe that there are any constraints on 4WD Auto (speed, distance, conditions, etc). I believe, although I could be wrong, that is ‘set and forget.’

that said, I believe that on those sunny summer days you will get better gas mileage if you toss it into 2WD.

I wanted auto 4WD for my Rubicon for Colorado winters. Sadly, it wasn’t offered last year.....

There are no speed constraints on the use of Selec-Trac in Full-Time mode.

Waste of gas ! I use my selec trac when it snows.

Guess you don’t have my 90’ on ramp where I floor it in the middle of the turn! Gets the power down great when the turbo spools up!

Thanks. We would too. We have command trac in our Wrangler. Select trac would suit our winter needs better. Summer road use would be 2wd.
