I've had a couple rental explorers with push-button but never needed it. Anyone comment on push-button low-range? I've never tried that either, but it seems like it would be difficult for the electronics to get right on an automatic transmission.
MY 94 Yukon had the button
My 97 Chevy x cab had the button
My 01 chevy has Auto 4x4 gizmo
Loved them all but that button thing is
BTW: I snow plowed with them all !!!!!!!!
Run hard and put away wet !!!
Toyota.......HA HA !!!! (and i owned 2)
NPG transfer case too !!!!!!
Also made in Syracuse NY USA
Shift into 4wd HI or 4wd LO on my new Silverado (manual t-case; special ordered) and the fronts are engaged. You have to pull the 4wd fuse to get 2wd LO range.
I still don't like the pushbutton; with the manual lever, you engage the gears for Hi Range or Lo Range; the front axles automatically engage. With the pushbutton, you select the range, and the truck engages the t-case. It is at least one more thing to fail.
It is difficult to find manual t-cases for the same reason it is difficult to find manual transmissions: The dealers stock up on them because they make more money on each one!! If the factory limits how many trucks the dealer can order (the infamous allocation system), then the dealers stock up on the high profit trucks.

To each his own. It would be a boring world if we all thought and acted alike.
When we were at an off-road park, my friend (has a similar truck, except his is automatic) was following me down some steep grades. In the middle of the day he asked if my brake lights were working. After he found out they were working, he asked why I never use my brakes going downhill.
Love that lo-range and 5.61 1st gear.

Mledtje, I disagree about pushbuttons only being available with autos. My buddy had a late 80's early 90's ranger with a 5 speed and a push button 4X4 system(that failed of course). He could not aquire low range, gathered to much speed for an uphill tight corner and ended up high centered in a deep rain rut on a 2 to 1 slope.
I think another good thing for an auto tranny 4X4 would be 11/2 times more low range gearing than a standard to help compensate for the lack of compression braking and a gear selector that actually selects the gear you put it in. 1st means 1st, 2nd means 2nd and so on...
Now I am glad I got the push button. The autotrac in the Chevy is the only way to go. I use it whenever it rains. Also works great when road is part snow/ice and part dry. I would not want a 4x4 without this feature.
Also if the system does fail it just stays in the last mode you were in - so it is no like it can't be driven.
-well, maybe. My '97 Explorer recently got "stuck" in 4wd Hi. If you you know anything about part-time 4wd, you'll realize that's it's pretty difficult (not to mention extremely hard on the vehicle) to make a corner. It's made me curse pushbutton 4wd systems ever since.
I know that ford has had auto hubs since at least 2001. 99% of the trucks on the lot today are auto hubs with electronic shift on the fly. I could not find a manual set up after searching 5 dealerships and had to order what I wanted. What may have you confused is that all of fords automatic hubs can be manually operated. Your Silverado does not have hubs. If I remember correctly it has a center disconnect front axel and IFS. As far as getting out in the weather to operate your hubs, don't. Leave them locked and just use the tcase to select two or four wheel drive until it warms up or you don't plan on using it for a while.
Maybe I'm misunderstanding you here. I know my 4x4s also-well enough to know that the transfer case should'nt be engaged if you intend to be going 70. As a matter of fact, it's probably not a good idea to be doing 70 in any of the low-traction conditions you mentioned. Listen-if your rear-end loses traction for 1 second at that speed to the point where the Autotrac system needs to engage the front axle...your "ruined 4x4 system" will be the least of your problems!
I'll agree it might be possible to damage a 4wd system if it is left in 4hi on good traction surfaces. But, it may not damage anything - I know someone who left his truck in 4wd hi for a few hundred miles at freeway speeds (70-80) without damage to the 4wd system. Certainly that puts more stress on the driveline. 4wd auto doesn't do that.
That said, I have a manual trans and a manual t-case, and don't want the automatic system and I certainly don't want to pay for it either.
and make a 200 mile round trip hauling a
snow plow up interstate 81 once a week.
Mounted on the nose not in the bed either.
I will drive 60 or so in autotrac mode
sometimes in just 4 Hi.
Don't bother me at all and
don't worry about breakage on drivetrain !
If the snowplowing won't kill it....
I put about 200 miles on it going back
and forth JUST plowing x-mas week too !
Just crusin' up the highway can't hurt !
Just my .02..........Geo
Was AK4x4 right when he said...
"I am going 70 and have the autotrac on automatic, then when I slip on ice, snow, or rain the system will activae the 4wd system. At that speed, boom yu've just ruined your 4x4 system! "?
Can you do 70 mph while in 4HI and not damage your truck?
This statement is false. There is no "standby" for the GM transfer case. It's on or off. "On" in autotrac, 4HI and 4Lo, "off" at other times. When the autotrac button is pressed, your transfer case is engaged, and your front driveshaft turns. But torque is NOT delivered to the front wheels until the front axle is also locked. It is the front axle that remains in a "standby" state until slip is sensed. You're not in 4Hi until BOTH the transfer case is engaged AND the front axle is locked.
This is how Autotrac (tm) works on GM trucks. Are you talking about something else on Dodges?
That's what I was thinking too-it's not like your front wheels/axles are forced to go from 0 to 70 in a split second when the power tranfers to them. The front wheels are turning along with the rear so there's not as much stress delivered to them as ak would like to have us believe!! And you also are right when you say while the Autotrac is engaged, the transfer case is engaged (on) and the front propeller shaft is also moving-there's just no power delivered to it unless a rear wheel slips!!
I will admit - shifting into / out of 4x4 with a stick is easier than trying to find a button to push at 40 + MPH. That is why I just leave the truck in autotrac when the road is slick.
By the way I guess I am old fashioned I like to feel the front end engage when I pull the lever it is one of the reasons I got a ram.
