So peaceful with the crickets in the background instead of some loud chitty music... finally getting around to showing my 93 YJ Wrangler Renegade 4.0 5spd 4X4 NP231 some love... gifted to me by mom before her passing and has had some questionable mechanics messing with it over the years, so now I have to question every part in it. Thanks for the info. Currently doing rear u-joints and rear output seal and your video helped me nail down which tranfer case I have to get the right seal.
Good lcuk with it! That is an awesome jeep!
I was a manufacturing engineer at NPG, Your 242J is a full-time unit with an interaxle differential. It was the best we made.
Magna moved the operation to Mexico. Gm is going to electric vehicles, they won't need a transfer case.
Can you please tell me what fluid I use for this exact transfer case?Is it NV 146?I have the 242 J transfer case 4.0 engine Grand Cherokee Laredo
As soon as you said all Jeeps should have 4 wheel drive, I hit the subscribe button.
thanks for the info. i'm finding it very useful in working on my jeeps.
Learned more about transfer cases and function from this video and your follow-up video than from all other videos I've ever watched. Thanks for that. Subscribed and have watched a half-dozen more!
Awesome! Glad you enjoyed it. Love you name BTW.
@@DEInTheGarage I’m going to watch this again a few more times! I’ve already watched it a couple in the past… but now I wanna get down there and see what mine says!
Thank you, that explains a lot of what I’ve experienced when wheeling.
thanx dude I knew none of this and I am very informed now added with my other research thanx again
Very helpful info. Thank you for taking the time to make this video.
Thanks for taking the time to comment!
Great explanation! Keep these vids coming!
Perfectly explained bruh , easy to understand thanks
Thanks for the video. It helps explain a few things that I needed to know. I also have the 242j. In a 2002 Jeep Liberty sport utility. I'm trying right now to put a chain in. The rear seal is also leaking. Fun fun!
There are so many great videos on Jeep GC's, thats why I love them. Mine is a 2000 WJ 4.7ho with a 247hd. Its a fantastic 4x4 system. This is a great video. thanks mate.
The 4.7 HO motor was standard in 02 to 04 Overlands, and optional in 02 to 04 Limiteds and Special Edition Jeep GC's. Yours being a 00, I doubt it's a HO 4.7 motor. Probably the standard 4.7L.
@@mrmo666 Hello Mr Ho, My engine was changed due to a spun big end bearing. The new engine is a HO as the supplier did not have a standard one. All HO parts are also fitted too.
Thanks for the explanation! This was very helpful 🤙🏽
Very good info brother,,!
Helped me a ton, thanks
The ZJs had the 249 Quadra-Trac transfer case, they had a viscous coupler in the transfer case....the WJs had the 247 transfer case, and they also came out with the Quadra-Drive system which had vari-loc front and rear differentials and the clutch pack in the transfer case, which is what you were referring to around the 11:15 mark. The gerotor coupler was used in the Quadra-Trac/Quadra-Drive transfer cases found in the WJs. The 249 and 247 were never used in the XJ, or MJ. both of those either got the Command Trac 231 or the Selec-Trac 242 transfer cases, or no transfer case if you bought a 2WD Jeep, not sure why anyone would but they are out there.
great breakdown. thanks so much.
Great video, learned a lot...thinking about swapping my 247 to a 231....
most helpful video ever
Really good info here. I didn't know about the HD cases NP offered.
This is such good info! How does everyone not know this??
They do now!
My 90 has the 229 AM unit with 261ratio. Happened to see the tag after replacing my Energy suspension tranny mount today.
GREAT VID! Thanks, now t want to see your other vids.
Please do :-)
Thank you so much, i got 247 on my 4.0L WJ
Good job man
Thank you good info.
What do you know about jeep commander 245j I need to replace the drive chain? Do I need to take the transfer case to neutral? I tried that the light blinks but nothing happens is that the motor drive that does that?
Thank you for that explanation
Interesting, thanks
Thanx for tellin me about the last digit being a 1 is a no no for turns and roads i gotta long bed sierra its a 2000 manual transfer case with a 261 very educational👍
I'd love to learn more about the NP245! My 4.7L Jeep Commander has it and it sounds so interesting from the stuff you said about it!
I will try to put a video together
Awesome video . Even Volkswagen used them .I have a NP-241VW in my LT 4X4.
Wow.. really? I had no idea about that..
Gold info man lml
First off just found your site love your content keep it up I have a 2005 Jeep Wrangler Rubicon unlimited my new process data plate is a 241j I'm wondering if they labeled it incorrectly with the 4 to 1 ratio
Great video. I have a 1997 grand Cherokee with a 249 it's leaking and not working right. I want to switch to a transfer case that has 2 wheel drive with 4 Hi and 4 low. The only thing that I found is a 242 J but it is in a 2003 liberty. Can I switch it out without changing the input and output shafts I believe they are both 23 spline. Hope you can help me with this problem.
You didnt mention mp3023 transfer case jeep grand cherokee 2013 ... thank you very much for the information above its really useful
Hi thank you for your video it helped alot .if ok to ask you a few questions .u need a new transfer case for my dodge .and now I was told I need to know if it's a 23 or a 29 spline shaft .and also if the electronic shift box qhen pulled out there is either aa hex nut or a torx nut the the box attaches to .and another video I saw they said it will tell you that with assembly number but I don't understand that part the I'm just concerned as it's a 4 hour drive lol so I don't want to hit there and find it's not usable .and I don't know if they seller understands what I'm asking lol is ther anyway to find that info out qith any of the numbers on the tag by chance ? Please and thank you
I have a 2000 durango 5.9 46re, I want full time awd. What transfer case you recommend?
Thank you! Ford f250 also has this!
GO TEAM VENTURE!!!
Thank You for the great video and information. I have a 2001 jeep grand cherokee larado with quadra trac. The transfer case tag reads 247 j . The left front wheel does not pull or spin when all four wheels are of the ground. Any ideas? Again Thank You.
Yes. Quadra Trac uses a limited slip trasfer case, but open diffs. That means - when locked - you are on guaranteed one wheel in the front and one in the rear spinning. Quadra Drive came with limited slip differential as well guaranteeing 4 wheel lockup
Hey guys great info video can you explain a trans code I got it's the p0743 the converter solenoid
I have gc 07 qd2 hemi np245j, the manual said fluid nv 245/247/249 is correct? Is the same tranfer case? Thanks for the video great
Thanks for this, I've got a 97 ZJ and when I bought it 10 years ago I didn't understand permanent 4wheel drive. I put 2 new tyres on the front and kept worn tyres on the rear. After about 20 miles it chewed up the front diff. At that time I failed to appreciate the need for even tyre sizes all round.
I dont know what mine is but its build by mopar
As 7/ddllàq
Hi can you drive with a worn transfer case if you never use 4 wheel drive? Jeep commander 2010 limited 8 hemi
Thanks
Any incompatibility with the electronics when swapping out transfers?
I worked at that Syracuse plant
The Renegade trailhawk uses a single speed power transfer unit. It has no low range gearing. It has a"low" mode but its just computer software that locks the transmission in 1st gear.
My 2014 Grand Cherokee is missing that sticker in the transfer case. Could it be a problem?
245 j is on my 2005 grand cherokee limited
hearing clicks and some play diving straight or turning and only happens if my foot is on the gas pedal anything past putting it........Quadra drive 2
I'm looking at a 231 D HD what does the D before HD represent? thanks.
MANN, awesome video I just purchased a 1993 Jeep Cherokee Laredo with a blown transmission, hopefully that last number out of the three is not a 9😮
My 1994 Jeep Grand Cherokee Laredo v6 4.0, when I turn my rear tires skip so I thought it would be the transfer case ratio249 so I see the 231 ratio won't work on my jeep I believe right?
Bc mine is all wheel drive and now won't get to that and won't drive anymore so is 249 can be a 242?
Hi I have a 2003 jeep Cherokee and need to change transfer box, what numbers need to match when looking for a transfer box online. Any info would be much appreciated. Thanks
So if I went to replace my case I only technically need the top and bottom numbers?
Hello. Two question’s please. I have a 97 ZJ with a 249. I understand from other videos earlier NP249’s the axles are not locked but newer NV249’s the axles are locked. How do you tell visually whether
you have a NP249 unlocked or an NV249 which locks both axles? And a second question. I was given a NV247, is there any benefit to switch from 249 (not sure if mine is locked or not. Just bought it) to NV247since I have it or should I try and sell both to get a NP242? Thank you so much. New to Jeep’n. BTW great channel and mine says 249 j.
What's the J stand for like 231 j. And 231 d. What'd the difference in those 2?
you know a lot about transfer cases!
so with part time does in 231 does the front shaft of t case kick out of gear. to prevent braking else where?
it does not. they are locked together so you can only use it on loose ground
golden
What’s the ad stand for on 2nd line
bro youre mad smart, what are symptoms of a front differential needing fluid?
Thanks bud. Just trying to help some like minded folks.
Definitely some grinding oh whirling/humming noise. If it is a limited slip diff you will get binding when turning at low speeds
Do you know if you could swap out a NV150 jeep grand 2005 and put in a NV245 without much hassle? , I know that is the some jeep grands there is a little lever to go into 4low, maybe that would also need to be swapped as well?
Well anything is possible, but that is actually a pretty heavy swap due to the electrical components in the 245. I cannot speak intelligently on the matter though as I have never attempted it or seen it done personally. Here is a JeepForum thread on the topic. I would suggest reaching out to the guy on there who did it as he can probably give you some much more reliable info. www.jeepforum.com/forum/f67/qt-i-nv140-qt-ii-nv245-swap-s-395686/
So my new question for you is. Should I swap the front and rear diff from my 01 to the 04 ? Since the ABS system is part of the Quadra-trac system I don’t know if the abs module would need to be swapped as well. Or should I just put the locker in front and rear. Thank you again for your input 🇺🇸
Yea, that would likely get you a nice beastly vehicle
hello, the video is great... do you know how to install a jeep cherokee xj transfer case from a grand cherokee 242hd if anyone knows, please help, thanks in advance
well i had to get dressed and crawl under my 95 xj to take a pic. its has the same numbers except the serial no. but thanks for sharing this info
That's good information. Thanks for sharing.
I am doing an engine swap in my Jeep and will be using an NP241C transfer case. (It matches up to the transmission I will be using.) I bought it as a stand-alone, so I don't know which vehicle it came out of. The serial number has a 95 in it and there is a 96 stamped on the case itself. So, I am assuming it came out of a 96 Chevy something (Tahoe, Silverado, etc.) I am struggling to find some information about it. It has a three-pin 4WD shift indicator switch near the selector. (Most of the ones I have seen have a two-pin.) I need to wire it to my engine wiring harness. Do you have any idea where the three wires should go? Or, do you know where I can get a wiring diagram for it? Thanks
Unfortunately I do not have any info on that for you. Sorry. I would get on a Chevy forum and ask around. i am sure someone there will have the info
Some of the Dodge Durangos had the 242HD transfer case, not very common finding them, but they're out there, I found one a while back in a Durango R/T with the 360 V8, so obviously they're pretty well built to withstand some pretty high torque through them.
If you can find a 242HD, you have found gold. I have seen them go for as much as $600 on JeepForum and Craigslist.
I'll keep my eyes out for one, would love to tear one down and compare to the regular 242J.
That would actually be awesome!
They were used in HMMWVs. They're plenty strong enough.
The whole "242 is weaker than 231" is a myth.
Can I put a 241J in place of the 242J ?
Does anybody out there know why my dakota 96 model would go fine in 4 hi but put it in 2hi like truck in neutral and will not even physical go into 4 lo like shifter stuck with 2hi goes in but no grinding nothing like in neutral
According to your explanation, middle digit represents number of positions. So what's the explanation for the 231 vs the 241OR in rubis? Both have the same number of selector positions and yet one has 3 and the other 4?
No, the first number determine the the number of positions and the middle number is a size or strength number. The 231 and 241 both have 2 gears (high and low), but the 241 is a bigger a beefier option. If you watch from 2:20 to about 4:00 i explain the first two numbers
Great channel thanks for sharing. On My 2000 jeep Cherokee XJ the rear drive shaft broke and I have just been using 4H the front wheel drive for about 6 months now. QUESTION do you think I am getting abnormal wear on the front wheel drive components from doing this compared to normal rear wheel drive 2H?????
Definitely. If you look at your front drive components compared to your rear (drive shaft, axle, etc) they are must smaller as they were not intended to move the vehicle alone. Not saying it wont work, but if possible find a drive shaft. you are going to be really stuck if you break something in the front!
@@DEInTheGarage Thanks for the reply. How are jeeps different then front wheel drive cars. It seems that the front wheel drive system was designed for off road extreme rough use. After watching a few transfer case videos it seems they designed the transfer case to be very robust.
@@DualTasticToday This is true, but you XJ was designed to be rear wheel drive when operating in 2wd, not front wheel drive. The components were not designed to carry the entire vehicle. I am not saying you are destroying the jeep or anything, but you are certainly using it in a way that it was not engineered for and at some point I expect certain front driveline components will wear out prematurely
@@DEInTheGarage thanks... 4H I think is a rear 60 with front 40% when in 4 wheel drive. You helped me a lot to understand. Thanks again.
Hooollllld up. Gotta clear something. I know this is old, buuut..
The 247 in the WJ had the gerotor in what they called the progressive coupler, with the clutch plates. Had the special fluid with the "friction modifier" in it. Does not take ATF4, which can wreck it. Used in the QuadraTrac II and QuadraDrive I. The same kind of coupler was in those funny LSD diffs.
The 249 in the ZJ had the "viscuous coupler" that was sealed but contained a weird silicone fluid. When it failed it would either lock up entirely or never engage at all. Took ATF4 otherwise, iirc. Could be wrong about that.
Feel free to berate me if required!
Nope, you are correct. the 247 is basically Varilok in a transfer case where ase the 249 is an odd non serviceable unit. It has been many moons since I recorded this video, so I cannot remember exactly what was said... did I misrepresent some of that info?
@@DEInTheGarage yeah got em all back-ards!
All good tho!
@@gcanaday1 Well thanks for catching it!
I believe this tag shows the low gear as 2.72:1 vs. 1.72:1. The Jeep Rubicon low gear is 4.0:1
That is accurate. The Rubicon has a much lower low gear
I have 3 WJ's 2 2wheeldrives an Just got a "1999"4wheeldrive that has a 242 "WJ" on the tag ???
I have a 244D in my 04 Ram 1500. Would the guys of it be the same as a 244? Any idea what the D is? It has three modes AWD, 4hi, and 4 low. Electronically selected. Gotta do a rebuild and can’t find much info on the 244d.
My understanding is that the 242J and 242D are internally the same. I believe the "J" is for "Jeep" and "D" is for "Dodge". The differences come in on the 242HD which has the same selectable modes as the D and J, but is beefier inside. Your D and my J should be identical inside.
New Process Gear was owned by Chrysler and was sold to a consortium of employees and investors becoming New Venture Gear. The only difference is the tag. It was again sold to Magna Powertrain recently.
Thanks for the video... I saw it very carefully, but you didn't mention (to describe) the number 0 of the second digit and the number 8 of the third digit. I have a 208 AM transfer case. I am also curious about the meaning of the letters AM. This transfer case it's on a Mexican Wagoneer 1982. Thanks in advance!
Hi buddy my jeep wj has a 247j my question is if i have my truck in 2wd or its in 4wd all the time so my display its broken and i just buy the truck thanks for let me know
4wd all the time. no 2wd on the 247
I have an 01 WJ AND and an 04
Both have a 247J but (01) is Quadradrive , (04)
Quadratrak 2
Both are 4.7 but what is the difference and what is in your opinion the best transfer to have it’s my hunting Jeep and I pull a boat often times
The 01 seems like the 4/4 works better in the mud. Thanks for the info sounds like you really know your jeeps 👍🇺🇸
Same transfer case (as you suggested) the quadra drive also has front and rear VariLok limited slip differentials which the Quadratrak II has open differentials. You 01 does better in the mud for that reason. as soon as the tires slip a bit, the transfer case and axles lock up for all 4 wheels are turning together.
"best transfer case" is open to a lot of factors, but all around I prefer the 242. It has a 2wd option which is better for on-road MPG and towing, but still has part-time and full-time 4wd as well. I am actually in the process swapping the 247 from my 01 Quadradrive with a 242. This configuration of the 242 with the QD Varilok axles is in my opinion the strongest you can have
I have a 234 AMC case can someone help me out on that and what that means I bought the jeep with that case the jeep Is a 1989 JY
I have a 05 Jeep Liberty v6 321 can I swap it out to something else, cause when I put it in HI it would slip out n drop down to part time.
Yes, you can. The easist would be to get a 242 from a Liberty
Is there any way to tell how many splines the transfer case has by reading this tag?
Technically you can take the year of the vehicle and the transfer case and search the internet to figure out which year with which t-case had which output shaft. There are always going to be outliers because Jeep and that is just the kind of fun games they play. Additionally, it is not just the spline count which must be taking into account. Different applications of different t-cases use different length input shafts.
tengo un jeep cherokee xj 2001 con una caja de las misma Model 242 y no se cual es la cadena de transferencia adecuada , si alguien me puede ayudar estare agradecido eternamente
Good video. Working on a Jeep Grand Cherokee with a 140. Jeep calls it a Quadra Trac? It’s an all wheel drive.
Yep, QuadraTrac I is the marketing name they give that particular 4x4 system. There is also QuadraTrac II, QuadraDrive, SelecTrac, RockTrack. etc.. All just names for different transfer case/differential combinations.
Its the same as the Quadra-Trac 2 but lacks neutral and 4Lo, its just a full time 4WD setup. Not sure if it had any sort of coupling to transfer torque between the front and rear or if it was a set torque distribution. Basically the typical Lazy American's AWD.
Hi there. Tq for yr video. I owned a Jeep Grand Cherokee ZJ 1997. It is now having transmission problem. Leaks and gear doesnt engage. I am from Brunei. My local dealer is not helpful saying the parts I need are discontinued. I have sent you an email seeking your help if you know any reliable supplier frm the US I can order the required parts. Thank you.
Do you know what the difference is on a Jeep Grand Cherokee 2004 it has a transmission casing number 2907/7 and then I got one of the 01 Jeep Grand Cherokee says 2901 can I use the 2901 in the Jeep Grand Cherokee it has a 207 the same tranny what's the difference
Cuz the transmission has a 2907 in it it has the transfer case 242 model and it has a plug-in on it and then the transmission out of 2901 transfer case it don't have a plug-in on it transfer case 287 can you help me out
Is there any direct line to you. Your a wealth of knowledge and I only live up the road in good ole PA. I have other things I want to run by you.
Absolutely. Shoot me an email at dandeoffroad@gmail.com or PM us on Facebook. We are always happy to help
I have a 2013 3.6 liter 4x4 laradeo with no 4x4 selector my transfer case does not have a tag lol
I have a WJ 4,7 with a 247 that burned up due to low fluid, What would you suggest installing? I will take it off road and use it as a daily driver too. LMK Please.... Great Video
Get a 242. It gives you 2wd which is better for driving around town and then you can lock the diffs together for off road. 231 is good as well, but less options
@@DEInTheGarage i have the same model (wj v8) the question is... Can we swap the original 247 to a 242 HD without change the differential (lsd)??
I'm trying to do a rebuild kit on my np 242j but how can I know which one to get. On eBay it says input is 16mm or 24mm.. A little guidance.. I want to know what year It was made too thanks in advance
The differences in the cases are standardized by vehicle model the went in. This means that if you have a 2000 Grand Cherokee with the 242J you can search "2000 Grand Cherokee 242J rebuild kit" and you should be fine. There is definitely a date included on the tag which should closely match your vehicles year (might be the year before you vehicles date) if it does not closely match then you will have to do some more digging
What they're talking about is the input shaft bearing. Its installed in the back casing half on yhe output side. 231 and 242s went from the larger bearing to a smaller one around 1994 IIRC. 94 model year you could have either. 95 and later had the smaller bearing.
Contact NOVAK adapters they sell a quality master rebuild kit that includes a chain. They should be able to walk you through IDing what you have.
please answer if possible
i have 2 97 grand cherokees both automatic,1 has 231 that has problems the other has a 242,, is it a straight swap
It SHOULD be, but Jeep in the 90'2 is notorious for switching up random things. Worst case you would have to swap the input shafts on the transfer cases to get it to work
@@DEInTheGarage rgr that thanks
Do you use ATF+4 transmission fluid for the transfer case?
In the 242 and 231 I do. 247 and 249 need their own fluid
@@DEInTheGarage Thanks.. I'll subscribe to your Channel
Is a 231 AMC transfer case the same thing as a NP 231? Can’t find a rebuilt it for my 89 Cherokee.
They are the same case, basically, but I believe the spline count on the input shaft will be different, so you would need to use the AMC input shaft in the 231J if you go that route. not a hard thing to swap over
95 xj swapping for a 99 xj both 4.0 both 231 both automatic any differences in those or can u point me in direction to figure it out i would assume its much like chava original question but double check
Hey fellas its me again.... 2001 Durango blown trans case... I found a 2004 durango with an RFE Trans like mine but dont know if its a 244d or not...tag says ...TITTJ019421154 19:11:38 then P52119554AA RFE Is this a 244D ? please say yes LOL
The j stands for jeep if it has a D then it's a dodge and ya u guessed it if it has a C it's a Chevrolet and on some of them that letter will be followed up with LD or a HD for yep light or heavy duty haha
im still to see another 147 transfere casse like the one in my 99 JGC
They are out there, but it is not a common configuration. Interestingly, they use the 142 in the WK Grand Cherokee much more.
I grenaded my 242 but I have a 231 rebuilt. Can I swap that into my 87 xj?
Sure can. you might need to swap the input shaft
So, correct me if I'm wrong.. I have a jeep Grand Cherokee (WK) 2008/9 (Canadian 10 of 08) 3.0 CRD Overland with an NV245 & as it states on the window sticker.. a "DGU" w5j400 (NAG1) trans, Quadra Trac II "active full-time 4WD system, 4 wheel traction control & 3.73 electronic limited slip differential front & rear axles"
It seems that the NV245 is now about the same system as the 249 you were talking about..
I'm looking to you because it appears I killed (loud gear/ grinding noises coming from the center of the car) the NV@$% while towing ~3000 lbs for 2000 miles with new tires on the front and 3-4/32 above wear bars on the rear tires.. Buying a transfer case now.. ELSD's are probably also questionable..
My 99 WJ 4.0 has a np147j or that's what the tag says the model is. Ratio is 272. It's a AWD and that's the signature on my transfer case
