I have no idea if your Jeep's symptoms are caused by the same source as mine was, but on my 1998 Jeep Cherokee (not Grand) with an AW4 transmission, I was experiencing delayed shifting into gear as you are. The problem I was trying to fix at the time was the transmission not going into overdrive. I eventually discovered it was one of the three transmission solenoids causing it. I was also surprised to learn it was the cause of my delayed shifting into gear. I assume the bad solenoid was "choking" the flow of the hydraulic fluid. You probably have a different transmission but it's worth checking along the same lines.
2 - 3 seconds when shifting from reverse to drive seems like an eternity when you're on the street. The manual for my AW4 states "Engagement time in D range should be a maximum of 1.2 seconds. Engagement time for reverse should be a maximum of 1.5 seconds". Hope this is of some help.

#610 of 1066 stuck in 4 wheel drive
Apr 13, 2010 (9:25 am)
I dont know if this will help anyone but recently my 2000 Jeep Cherokee (not grand) was stuck in 4 wheel drive. ....This is what happened .. I couldnt figure out why my Jeep was acting up. it was VERY hard to turn but would drive straight fine, but shake a little as I went faster. I used my 4 wheel drive the previous night and shifted it out of 4 wheel drive and back to normal that night as well before parking. I figured out that it must still be in 4 wheel drive by the way it was acting. So I called my (auto magician dad).. He told me right away that I was stuck in 4 wheel drive but for some reason was know showing me that on my dashboard. He asked me when I put it in reverse if I had backed up very far, I replied a few feet, he told me that was probably the prob. .......so I put my foot on brake,Jeep into neutral, Jeep in 4 wheel drive lever position..prev was not)then shifted back down to 2 wheel, then off lever.) put vehicle into reverse, then backed up a lot farther this time, immediately I could tell I could drive normal again. It was like it kicked it out of 4 wheel when I backed up far enough. I know sounds weird... but It worked

It sounds like a drive train/transmission mechanical problem because it works OK in reverse. If there is a way to disable awd and make it 2wd, the results would help determine the source of the problem. Otherwise, you should be able to get a repair quote for no more than $100. It will be an expensive repair.
If I was working on it myslef in nothing to lose mode, I would remove the transfer case and examine it.

My jeep shop manual has a troubleshooting guide and one section is for delayed shift. They list 14 possible causes and I don't see how a dealer could overlook them, except for 1 possibility that sounds really odd.
DELAYED ENGAGEMENT FROM NEUTRAL TO DRIVE
CAUSE: Torque converter drain back (oil drains from torque converter into transmission sump).
CORRECTION: If vehicle moves normally after 5 secs after shifting into gear, no repair is necessary. If longer, inspect pump bushing for wear. Replace pump house

I just purchased a trans for my 98 Grand Cherokee, come to find out it is a 43re.
I believe that my trans is a 42re, can someone tell me what the diff is and if it will
work in my 98.

Hello mtylerjr ,
My issue(s) are almost identical to yours! I just purchased an 05 JGC with the 3.7 V6. I have an identical shutter around 40-43 mph or 1400 - 1500 rpms. I also purchased a 3rd Party Extended Warranty through the dealer ( 4 years/ 50,000 miles ).
I'm curious if I could get your advice on how best to handle this issue? I'd like the warranty to cover it but I'm hesitant to go in right away based on your experience... I've read some other posts where the dealer / mechanic says 'that's just the way jeeps are' but it sounds like your issues were fixed? Do you think I'd be better of 'living with it' for a few months and then taking it in?
Any advice you have would be GREATLY appeciated!

I dont really know what advice to offer. If the shudder is minor, the warranty company may not want to do anything. If it is major (sounds like grinding) and the mechanic agrees something needs to be replaced, you are better waiting (according to my mechanic) for at least a month or so before making a claim, so they dont pull the "preexisting condition" thing.
In my case, the warranty company and dealership both chipped in about $800 towards my $2750 repair, but made me sign a release form promising not to sue them just to get that much. After that, I realized I probably did have a legal claim, but it was just so much hassle.
Just 2 weeks ago, the jeep started making whining noises that I thought was the transmission again, but turned out to be a bad belt tensioner and a failing AC compressor coil. When they replaced the tensioner and took the bad coil off, it not only got quiet, my MPG went up by 3MPG - apparently the thing has been dragging the belt even while not being used, for the past 15000 miles... doh! But it runs better now.
Good luck with your jeep. Sorry I couldnt offer any more advice.
