Hi there, new the forums. I've been a happy WK2 owner for about 18 months now. I have a 2014 Jeep GC Overland with Quadra-Trac II, Quadra-Lift, and Selec-Terrain. Both the local dealer and a trusted local mechanic are telling me that the transfer case clutch has gone and it needs a new transfer case. I was in the line at a a coffee shop and got a service 4wd message. I searched the forum while I was sitting there. It seems like a pretty common message over the years, although not as much on a WK2, but I saw where someone mentioned cycling into 4wd low and back to try to get it to reset. I tried this, but now mine is stuck in 4wd low.

The car is in great condition. It hasn't ever been off road. The tires are the same size and have roughly the same wear. Everything is stock. My dealer said they haven't seen a TC failure on a WK2, and I can't find much online either.

The primary code is C1438. The dealer preformed diagnostics from tech authority including manual commands, resetting the transfer case control module, and verifying correct voltages were making their way into the case. Manual commands didn't do anything. No noise, nothing - as if something is stuck. Voltages were correct, so it does seem to be something within the case.

I personally believe an actuator or something is stuck or has broken inside the case, but haven't looked myself and can't find much info at all on the QT-II TC.

So, for the questions: 1) Has anyone here removed a TC from a WK2? If so, how hard is it and what needs to be removed (whole exhaust system, trans, etc.)? 2) Have any of you seen an actual failure of the TC in a WK2? 3) If I can get it fixed, would you recommend getting rid of this Jeep? A major failure 4 years in seems out of the norm. 4) Does anyone have a diagram of this Tranfer Case?

Thanks so much! I'm going to replace myself if possible - just want to do some data gathering.

Dang - I hate to hear that. Did the dealer do it for you? It looks like there’s a new part number. Do you know if you have the newer revision? Trying to figure out how to proceed.

I have got a service 4wd message, an ABS light on and a traction light on today. 2014 summit V8 with 60k miles. Dropping it off tommarow will see what they say.

How many miles do you have? Isn't that covered by the 100k powertrain warranty?

If you're out of warranty I'd avoid the dealer and have an independent mechanic swap in a used unit (from a newer model). I would suspect that the rear of the exhaust has to be removed as it wraps around the back of the transfer case and also intertwines the rear driveshaft. I don't think it would be a bad swap on your own in the garage though. Probably a heavy bugger.

@silvermax04 the three amigos is probably a wheel speed sensor.

I had the exact same problem. The dealership wanted me to purchase a new transfer case. The solution was to replace the transfer case motor. It is a sealed motor, and eventually the seals go bad letting air and water in. The motor goes bad. A new one is about $300. It is held in with 3 bolts and two electrical plugs. It is located on the rear side of the transfer case. Easy change. Another issue that causes this is the DTCM can go bad. It is located under the driver’s seat. It is plug and play. Again, $300. If these don’t work, then you need a new transfer case. Your fault code dictates that it is either a transfer case motor or DTCM short though.

Something similar happened to my 2006 grand cherokee everyone was telling me to replace expensive bits but I looked up one of these sites and found a workaround for it involving pulling a fuse, cycling 4wd low and driving back and forward. Replaced the fuse and its worked great ever since. Surely there has to be something for the newer cars rather than expensive replacements.

Yes, I have a 2014 GC with 4 wheel drive, and at 55K miles, I had to replace the transfer case. Very expensive and unanticipated, but I still like my vehicle. Not sure I would buy another one though, I have had other issues, so I am disappointed with the reliability factor.

Thank you, it ended up being a failed wheel sensor and failed ABS module no issue with transfer case. Parts took 4 days to come in but is fixed now and was covered under Maxcare along with rental for the week.

Well that didn't last long service 4wd and ABS light is back. Roll the dice and back to the dealer tommarow.

Best of luck to you on this, I should tell you that yes, I had to get a new transfer case, but the first one failed, so they had to order another, my vehicle was out of commission for 4 weeks. (and that is with paying extra for fast delivery). Nightmare....

So... you're telling me the dealer wanted to change something expensive instead of actually troubleshooting? :confused:


Thanks for the bits of info, I'm sure I'll have to address this soon. I think dealers would be miles ahead if they'd just browse this forum once a week or so. Most of the troubleshooting would be done for them. :D


Transfer cases are usually durable as hell. In the 94ZJ we have, the original one was an NV249, which the viscous coupler started to seize up, so we swapped in an NV242 out of a 91XJ, that had... I dunno, maybe 250K on it or more. The t-case had no fluid in it when my friend inherited the jeep, we filled it up, and he beat the snot out of it. (has a heavy foot) Swapped it into the ZJ around 200k, I think. It has almost 300k on it now... so that t-case has been around the block, beat on, swapped, never opened up, never repaired, and it still works.


Even the t-case in my 94 bronco (BW1356) never failed. The connector for the shift motor got a bit corroded once, and I had to clean it up, but other than that, perfect until 247k when I sold it.


They should be pretty much lifetime units, unless you're abusing them with larger tires, and a lot of low range use.

I agree with you. When I had my '94 Explorer all I ever had to do was toss a new shift motor on it which was a half hour job at most and relatively inexpensive.

My '01 XJ got a new chain and nylon guides at 190k only because I had it broke apart for the slip yoke eliminator. It didn't need any of it but...because you're in there.

I wrecked the selector gears in my 242, but that was my fault, not the T-case. Found a used set on fleabay, swapped, still good. I gotta post up in the WJ forum, gotta get this thing out of my driveway, and want someone to buy some cheap parts from me before the junk yard gets it. lol

Picked up the Jeep this morning again and they said a loose connector from the first repair, got 10 miles down the road and same lights back on again. Back to the dealer for a third try on this.
