You've read wrong, the 247 is a great transfer case. What do you mean it's "Going out". The 247 with proper fluid changes should outlast the engine and transmission.

I just got a Private message from this guy. He was a real prick about my previous post. He sent me a link to 1 website that has a 1 paragraph summery saying the 247 "Can be problematic".

So one website says it can be problematic and all of the sudden it's a terrible transfer case? The only reason you would ever have a problem with it is if you put the wrong fluid in it (or didn't change the fluid).

i see why you are pro 247. YOU HAVE A 2000 GC for sale.( wonder why). anyway i said from the start i was checking what options i had. your the one that came running like the jeep police. besides i wonder why they only put them in the 1999 and 2000's. hum, must be junk.

it is a good awd transfercase, the only thing that goes wrong with it is the progressive coupler can wear out if you use the wrong fluid or don't change it at the recommended interval.

and fyi anotherbasscat, jeep is still using the 247 and 147 transfercases, they weren't only in two years. i'd say 9+ years is a good model run.

anyways, what exactly is your case doing that it's going out? has the fluid been changed recently?

Wow basscat- looks to me like you're getting off on the wrong foot here. Lots of good people here to help you out, but keep up the attitude and you might find the help pretty scarce...

Anyway- to answer your question...

I've been reading up quite a bit on this (read I haven't actually done a swap, so get confirmation on what I'm saying)- I blew out my VC and am thinking of swapping out the 247 for something w\ a 2WD option (ie 231 or 242, maybe even an Atlas).
First- what's wrong with your TC? Most common failure seems to be the viscous coupler. I found a write-up a while back on replacing this- didn't look too hard. Do a search and see what you find. If this is your DD and you're not doing a lot of rock crawling or other heavy offroading, repairing your existing TC is probably your best bet. Most WJ's out there are running the 247 w\o problems- don't let one bad experience w\ this TC burn you on it. The VC is a pain when it goes, but most people don't have trouble with it.

If you're set on replacing it, it looks like the 242 is a direct bolt-in replacement if you can find one. If you really beat on it, the 231 is reputed to be beefier than the 242, but there's a bit more to the install. I found write-ups for both of these on other sites, a little searching should turn them up. The 231 also has greater aftermarket support, such as a 4:1 kit and I think I read about a twin-stick kit somewhere or another as well.

IIRC, JF doesn't like us posting links to other sites, but a google search should turn up all the info you need for either swap.

Good luck.

the np247 doesn't have a viscous coupler, it has a progressive coupler, and most people wouldn't know when it goes out as it reverts to 2wd mode only.

Interesting- I've repeatedly seen it referred to as a viscous coupler, even in parts catalogs, but looks like you're right. Unless I'm completely mis-diagnosing, mine appears to have been sticking for some time, keeping power to the front wheels full time. Now that it appears to have gone out I don't hop in slow speed turns (I always blamed my Aussie before) and my gas mileage jumped substantially. Thanks for the correction!

BTW- JPMagazine has a fairly decent write-up on a WJ 247-231 swap.

The 249 uses a VC, and it eventually fails. The 247 uses a PC and shouldn't fail as long as you change the fluid with the correct 247 fluid as recommended.

Question

Basscat - why do believe your 247 TC is going bad? The key to long life of the 247 is regular (MOPAR fluid) fluid change (every 30K or so). I'm am 132K and it works pretty flawless. I would start with a simple fluid change (MOPAR part number 5016796B, 2quarts) before spending big bucks for a TC swap or major repair.
