jdhallissey so sorry to beat a dead horse on this. My heep shifts just fine into 4hi and 4lo but the light never comes on anybody have this going on? I am not going to call it a issue because it is a dummy light and if you can't feel your in 4hi or 4lo trade it in.

cork1958 My question has been answered. I shift my Jeep on the move (4H) with even pressure on the pedal and NO clutch. Finally tried it a few days ago.

Shifted smooth as silk with absolutely no noise, jerking, grinding, or anything. In fact, if the part time light hadn't came on, I wouldn't have known I was in 4WD.

cork1958 Just relocated my owners manual. It DOES say to use the clutch when shifting into 4lo and to be rolling 3-5mph, but it doesn't specify using the clutch or not when shifting into 4hi?

Man!
Am I confusing myself!!

I'm going to believe that's how it is. Use clutch for 4lo, don't use clutch for 4hi. Going to get a chance to check it out sooner than I hoped, as far as snow goes, as we got some last night already. Not much, but it is coming, as much as I hate it!

I'm "up north" but definitely want to stay happy keeping my Jeep running more so than having "fun" abusing/tearing the thing up!!

I'll use my quad for abusing things and tearing things up off road!!

AWD vehicles have a differential off the transfer case to allow the front and rear wheels to move at different speeds. That's also why you shouldn't use 4wd on dry paved roads.
i find it funny how you see those guys in Subarus stuck in little dirt with only 1 of the 4 tires turning

cork1958 Thank you.

Believe it or not, haven't even tried shifting it into 4WD yet and have had it for 5 months now!! I KNOW it works though, but figured with my luck, if I tried it without being absolutely positive about this, something major would screw up!!

Thanks again

Actually,
You CAN be moving to shift into 4LO, and in fact, in my owners manual, it recommends doing so, but no faster than 3-5MPH, so I'm ASSUMING you just shift in 4LO with no clutch also?

When shifting into 4 wheel drive with manual transmission, it IS necessary to use clutch, correct?

Thank you
No, your transfer case doesn't know when your clutch is engaged, it only knows if your transmission is in neutral or not. You only need to be in neutral to shift into 4lo You can be driving down the road and shift into 4hi in gear with no clutch.

If there's a decent amount of snow on the ground and your driving in 2 wheel drive then you can't go very fast, but if you put it in 4x4 you can go a lot faster. You can make it threw snow in just about anything, I see people doing it in neons and geo metros all the time...in my rear view mirror.

Michigan gets a lot of snow, and when everyone else is snowed in it's fun to go play in the snow when nobody else can. You slide all over the place and there's no other cars to get in your way, the worst you do is slide into the ditch, the snow usually cushions you enough to not hurt the vehicle to bad, key word usually

Who cares if you break something, as long as you had fun doing it.

emev0l I've been known to push things a bit, I've done 85 in 4x4 in a couple vehicles in the snow, I've never had a problem with any of my transfer cases. I don't think it will hurt anything but I really don't suggest going that fast in 4x4 or in bad weather. Your transfer case is spinning the rear shaft when your driving in 2 wheel drive at high speeds, I don't see why splitting the power would hurt it. AWD vehicles vehicles do it constantly.

jp'rs_peep'rs When i'm out and about I use both 4hi & 4lo on the fly! For 4hi it's anything up to say 45-55 mph and for 4lo I get so its just barely roll'n and pull that stick quick, or it grinds the behind.

Triple88a well top speed in 4x4.. if you need the 4x4 then you'll be in bad weather.. i wouldnt go more than 65 in bad weather.. if you are on nice or wet asphalt, then 2wd should be plenty good for it..
11-09-2008 03:51 PM
ExDementia I can't stand automatics.

So whats the max speed you can drive in 4wd? If you can just shift in at 55 I assume that's just for shifting and you can drive faster than that, that's how it was for my Ranger.
11-09-2008 10:01 AM
slf41002 Its pretty much normal.It will do it worse at cold temps after sitting over night.Or at least mine and the few automatics I have had at the shop have.They all were the same way.
11-09-2008 09:09 AM
jgano23 it sould just seem slow if your used to a manual. when i drive my cj for a while and then go back to driving my tj it seems a little slower b/c i'm used to the immediated engagement w/ manual. does the auto make any noises when shifitng in?

I'll give that a try...

Anyone have any thoughts on the delay into reverse? Normal? Or possibly tired?

Triple88a flattietj sometimes 4x4 on the fly is good for snow.. you see a patch of snow and you're going 55.. its good to be able to shift just to make sure you have the extra 2 wheels if you need them.

As for 4 lo. In one of the jeep videos i saw jeep recommend shifting to 4lo while in drive with like walking speed.. they said it will make grinding noise..
I rather not take my chances and just like flattietj i stop, shift tranny to neutral, then go to 4lo and then shift to Drive again (or 1st in my case)
11-08-2008 10:55 PM
flattietj i have an 01 and everything is the same as what you have so the info they gave me on purchase will be good....you can shift on the fly 100% safely at 55mph but ive dont it at 65 just to be a tool but why would you need 4x4 at a speed faster than 35mph......for 4lo i always come to a completes stop and put it in neutral and then engage it.....somtimes theres a grind sometimes not but its not to worry b/c np231s are everywhere if you tear it up

Shifting Into Four Wheel Drive And Transmission Question

When I test drove my new Jeep today, I drove it to a hilly dirt lot to test out the four wheel drive to make sure it worked. I've never done this with an automatic transmission vehicle before so I stopped and put it in neutral (I'm not sure why). It shifted into 4HI ok but when I tried to shift it into 4LO it made a grinding noise but did engage. What's the proper procedure for shifting into four wheel LO? Is it ok to shift into four wheel HI while moving? If so, what are the speed limits for doing so? It's going to take me some time to get used to the whole modern Jeep thing but I'm loving it so far. What an improved ride over the CJ! That coil sprung suspension is a dream on the highway.

Another question I have is with the automatic transmission. It shifts great while driving, however, when I shift into reverse, there is a slight delay before it engages. Is this normal? I'm talking 1.5 seconds or so max? Once in, it works fine. There is no slipping of the transmission in forward or reverse at all and it drives great.
