Hello everyone, new to the forum and looking to see if there are any write ups out there for swapping the clutch pack out in the NV 245. I guess I should start off by saying I have a late 2008 CRD that has been a pain in the but since I bought it. Now it turns out it's throwing C1438. When it was in for the P73 I had the dealer pull the code and diagnose it, and they said it was the clutch pack needing replacing. Sooo...looking to see if there's any write ups for it floating around? I did find one on the SRT Tcase which is essentially the same as the 245, as far as I can tell, but nothing particular to the 245. Thanks for any help!

First, welcome to the forum. How many miles are on the vehicle? I find it very hard to believe that the clutches are bad, unless the vehicle has been abused, run low on fluid (or never changed fluid), mismatched tires have been used, or it has been malfunctioning forever. The 245 case is pretty bullet proof unless totally neglected. How did the stealer diagnose this? I am sure they're just going by the DTC (C1438) that they pulled from the OBDII system. Did they reset (clear)the code so you could see if it comes back on? Does your Jeep fall under the N23/P73 recall? The stealer should be able to hook their StarScan tool up to it and operate all the components in the 4WD system to verify the basic system integrity. Also, does it work normally and have you tried running it it in 4WD low? How does it work? It's really pretty hard to diagnose bad clutches without splitting the case. The DTC codes sometimes lie too. The common stealer answer to almost everything is to put in a new one. Just check out some of the other threads of people taking theirs to the stealers. It really is sickening how they try to "rape" the unsuspecting customer. Have you changed the fluid lately....using the correct 245 stuff? Good luck and let us know how it goes.
Also, here's a sample of this problem on a low miler driven by grandma: http://www.justanswer.com/jeep/70b9p-jeep-commander-overland-2007-commander-46-000-miles-quadra.html

105K on it. I too find it very hard for the clutches to be out. This vehicle has been meticulously maintained prior to me getting it and I do the same. I pressed the dealer to ensure it was the clutches. They assured me they did the procedure correctly. Funny thing is, the only option they give you is to put a whole new tcase in. No mention of slapping in new clutches or getting a rebuilt one. Funny how that works. This jeep has never been offroad or wheeled hard. I can shift the tcase in neutral, but 4 low is a no go. The stealer claimed they cleared codes and it came right back. I saw the link you posted and assume those are the steps they took to come to the conclusion of the clutches. What I don't like about these vehicles is I don't have access to the TC codes unless I shell out a considerable amount for a high end code reader. Seems pretty lame. I just changed my fluid with the proper NV245 fluid. The stuff that came out looked exactly like what I put in. I haven't measure the circumference of the tires on it now, but they are getting worn and I'm getting new ones on tomorrow.
As an aside, why does chrysler allow their dealers to do this sort of thing? I have a bad taste in my mouth with chrysler, as shortly after I got the vehicle, the rear pinion bearing went out. I was deployed and they took full advantage telling my wife the whole rear end had to be rebuilt. $3k later she was going again. I have the parts and can find no discernible wear that justified a whole new ring and pinion.

Call Chrysler and complain. They don't know what you don't tell them, and dealers aren't supposed to be throwing whole new assemblies at easy and cheap component repairs ("you need a new tranny" for a solenoid pack, "you need a new transfer case" for a clutch), never mind taking advantage of you for work you don't need.

Get on the Chrysler recall web site (I don't remember what it is though) and see if your vehicle needs and/or has had the N23 recall AND the P73 customer satisfaction notice complied with. Not being able to shift into 4 Low is a common issue AFTER the recall has been done. It has nothing to do with the 245's clutches. It's the FDCM (Final Drive Controller Module) that Chrysler screwed up when they tried to bandaid a minor problem. This has been going on for over two years now and people are still fighting with Chrysler over this issue. Also, if these recalls/satisfaction notice has been done, it shouldn't cost you a penny to get it fixed, so don't let a stealer try to rip you off. JeepCares on this forum may be able to help you in this regard.
One other thing, do a search of this forum for N23 and/or P73, and you'll find a very lengthy thread outlining this issue and the problems people have had getting them resolved. Good luck and let us know what you find out.

I'm tracking on all of that...but supposedly dealer says the only code is C1438. Yes, it does have P73 done which was completed without my knowledge when they rebuilt the rear end. I can still shift into neutral, which would tell me the shift motor is fine and communicating with the FDCM correctly. Honestly, chrysler has lost any and all credibility with me. I'd rather just move on and fix this myself without having to talk to any of those dickheads. I don't really want to give them another opportunity to screw my family over. I deploy soon, so I'll probably just end up ripping the T case apart and putting in new clutches if the code is still there after the new tires and when I get back in a few months.
Thanks for the ideas on this!

I was also informed my clutches were worn during p73. They cleared the codes but the light came back in less than a week, and stays on. My 06 has about 114,000 mi. The dealer says they can change the pack in 4 hours at $950. I haven't had it done yet. I did have an episode where the wrong transmission filter was installed before I bought it used. The filter split open and was bypassing fluid inside the pan. But I took it to the dealer right away so don't know if that was enough to wear down the pack.
Talk about a timely thread. I took my '08 crd in for the P73 this morning and they just called saying it was ready to pick up. So I'm waiting for the shuttle as I type this. I had the service message for the last 3 weeks and was getting tired of seeing it and figured I didn't have much to loose on the P73 recall and it might fix my issue. The service tech ran the code when I dropped it off and it was - - - - worn clutches in the transfer case. They said it did clear the code. From what I've read that is probably only temporary. I'm going to start looking for a pre p23 fdcm.
Picked it up from the dealer and all is good for now. They told me they drove it about 20 miles and the message never came back. I'm thinking a full blown Ferris Bueller treatment. Honestly, right now I don't have anything to complain about except the shuttle guy told me they gave him a Hellcat to drive as the shuttle vehicle, LAST WEEK! Damnit! I should have done this last week. I would love a ride in a Hellcat.
BTW, I'm 50 and this was the first time I've ever taken one of my own cars to a dealer.
Now that the recall stuff is done, there is a hot tune with the dpf delete in my near future.

Wow....I'm glad to see I'm not the only one with this issue then after the FDCM updates. Think I will put in a call to their customer line and see if they will do anything towards this. If they really are worn clutches, they need to figure out how to build clutches that don't wear out in 100K. I understand some of the SRT guys have issues with them in the NV 146, but they are doing 4 wheel burn outs regularly.

Any of you that have had P73 done have most likely also had N23 done. There have been several people that have paid to have all kinds of related parts replaced (at their expense) and none fixed the problem. The only fix everyone says works is to have BOTH N23 and P73 done CORRECTLY exactly as indicated in their instructions.....which some stealers don't do. Take a few days and read up on this issue. Here's just a couple references....if you go to the search portion of this forum and type in, "N23" or "P73" you'll get tons of hits:

I would also urge you to PM Ryan, the so called "JeepCares" representative. He supposedly can help if you're having problems with this issue. Keep us posted on your actions and their results. Good luck.

Mine only has 55k and the last 15k is mostly hwy in 8 months. I wondered how a mechanical device can sense worn out clutches and the only thing I can figure is speed sensors on front and rear that differ more than the fdcm program expects.
I searched a lot today on the subject of worn nv245 clutches. I never found a kit with new clutches, but I did find this which is an interesting read:

Does anyone change their transfer case fluid every 15k miles?

That document lays it out. Basically using an encoder and based upon how far the motor has to move to engage the clutches, it can sense if they are worn. So either they modified the limits in the P73 software, or somehow ours have worn down. My bet is they changed the threshold and ours are now commanding a voltage outside the specified range. AKA:code C1438 is commanded and the dealer says oh, they need a new Tcase because the clutch is worn. Super lame. Parts are ~$250 and can be done in a few hours, but that's outside the point.

Unfortunately they would have to say that. I believe a few folks have familiarized themselves with the procedure(s) and watched the tech. do his thing to insure it was done correctly. I am also pretty sure that any time the problem is not resolved, it is mostly because the procedure(s) were not followed to a "T". There have been very few that have actually had a malfunctioning component....at least until the stealer got their hands on it.
I did know that before. Sorry for my brain fart.
Very interesting read. Especially the part about mismatched or non standard tire sizes causing the computer to send codes. I run 265/70/17" tires. When p73 was done the codes given were warn transfer case clutches and warn rear brake pads. I had replaced all 4 brake pads a couple years ago and always knew that the front pads wear out way before the rear. So I was skeptical. However, I could see visually that my rear pads were worn, really worn. I've since found out that vehicles with electronic stability control will wear rear brakes down at an excellerated pace by constantly applying bits of brake pressure in order to keep things stable. But I remain skeptical about worn clutches in the transfer case.
What was the code for worn brake pads?? Don't think I've ever seen that one. (and I've seen some pretty worn out brakes)
