Problems shifting into 4Low...

Ok boys heres the deal the girlfriend just got a 1997 ZJ Limited 5.2L (giving you the stats because I don't know what t-case that equates to, Quadra-trac is it a 249?) I was playing around with it earlier and decided to see how it shifts into low. I put it in N, pulled it straight back into low, let it roll forward a little then put it it D. IMMEDIATELY it started making a grinding noise so I quickly threw it in P after a second I put it back in N and shifted into 4Hi again and it was perfectly fine...

Now I know when I use to put my WJ in 4Low when I first started wheeling it would sometimes bind up and give me problems but after repeated use it started working smoothly. Seeing that this is my girlfriends new Jeep and I don't want to blow up her t-case doing something wrong I figured I asked before I just kept shifting until it worked. Any ideas?

thanks in advance
joe

Not sure if it's the same with the WJ, but you're supposed to be rolling in N at 3-5 mph to shift into low. Did you check the linkage? It might be out of adjustment and therefore not letting the TC drop all the way into low.

I know that with my 242 transfer case I have some trouble getting it to lock in low sometimes. You have to make sure engages good before going into drive, or it'll be unhappy. I don't imagine you wouldn't notice this. The VIC should notify you if it's not fully engaged. It just won't light up "4-wheel-low", but again, I don't imagine you need that to know if you're in it or not. I have had those doy moments though where I didn't get it fully engaged and felt like an idiot. It happens.

just reiterating the previous comment, but you'll feel it when it's fully engaged, you can almost feel like a notch when you got it right. just pull hard and fast and you should get it. it happened to me too. just got show it who's boss. lol

Haha you see I don't know everything... The WJ doesn't have a light that notifies you that it is in low. Tomorrow I will try again and this time I will pull until I see the light...

Really? I mean you get the little orange tick mark next to the shifter but nothing pops up that says "4Low" on my 2000...

It was a 4-Low light on the bottom right corner where all the gauges are located. It glowed either Orange or Green. But pretty much all you need to know how to tell if it's in 4-HI or 4-LOW is to compare the RPMs while accelerating. You'll see a dramatic difference. I'm still learning but that's something I noticed right away. God I missed the roar of that I-6 in 4-LOW, you'd swear it was an 18 wheeler. Makes ya go hard lol.

Haha no I can tell when the Jeep is in 4Low I just couldn't tell when it was fully engaged before putting this ZJ in drive. My WJ always has a nice smooth shift into low you throw it in D and feel that extra push trying to over power the brakes... I love that 4.7

Try throwing it in reverse, roll a couple feet, then drive. Sometimes that helps.

Actually, it's more than a light. On the VIC in front of the shifter you'll see the image of the Jeep and four wheels, and in 4-low all the wheels will light up to show it's in 4wd. Then it will light up a notice that says 4 Low. It's easy to miss that last hitch in getting it to lock. I've done it in some pretty slippery situations, too. A bad time to miss!

I'm sure you'll get it to lock though now that you know. The Jeep just wants you to work for it.

If the ZJ has the 3 position 249 transfer case (4Hi-N-4Lo), all you need to do to shift it (when it's everything is working correctly) is to put it in neutral on the transmission and shift straight through to 4Lo on the transfer case. Do not pause in neutral on the transfer case. It should shift just as smooth as the transmission.

I even made a video of it to show what it's like. Take a peek.

Check to make sure that the linkage arms are all in the correct place. My 94 GC with the 249 has a socket in the transmission and one shaft from the linkage has to fit in there. My TC wouldn't shift into 4LO because the shaft had come out of the socket.
