and finally a T case story. my 02 TJ had 240,000 miles on it's original oil. i drained it and it had a faint cloudiness of metal in it. added Mobil one full synthetic atf 4 and no problems.
I got my 6 pinion planetary from an '00 1 ton chevy with the 241, and the wide chain and sprockets came from a V8 durango with the 231D HD. Best part about it was that the guy at pick N pull didn't know what it was so he charged me $40 for the lot of it.
When using a transmission jack I've found that an old sheet of rubber or something kinda sticky like that works well to keep the transmission or the transfer case in place. Metal on metal is crap for friction in this case no pun intended.
I read this on Novak's website: "ATF is the factory recommended fluid, however many individuals have chosen to run a straight 30 weight oil or 5W30 in a mineral or synthetic. Our experiences with these and those reported to us by our customers indicate positive results in noise reduction and wear resistance." I started using 5w30 about 3 years ago. I'll be the wide chain setup and SYE soon and I'll look for anything abnormal but I didn't have it apart before I changed to the motor oil.
The aw4 defiantly takes dex/merc but the t case it's safe to use atf+4. I actually did use the +4 for the t case intentionally because it's a full synthetic fluid. It's just bearings and a planetary set, no clutches to be harmed.
When I took my t-case out after I had all of the nuts off, I carefully positioned myself up by the front axle and kicked it away from the Bruce jenner. Thing plopped right on to the ground just mint
Badass! I was just reading up on this 231j to 1/2 ton Dodge 231d or np241 upgrade the other night. Not sure which, most forums say the 6 pinion deal comes from the 241's and others say 1/2 ton dodges.
Good video Nick.Your videos helped me a lot.You inspired my new build Project w j.The intro video is published now.I start the build video next Sunday.Keep the videos coming.
t case install tip. hold it so case is vertical. slide it is just a bit to get the shaft on.ALMOST to the point where the studs touch. then rotate the case clockwise up and then slide it the rest of the way in. this way, you only need to grunt it in by hand to get the shafts to meet, and stay out from under that fucker it will kill you. if you sit under and head in the trans tunnel looking forward. have the front shaft yoke between your legs and lift it up and slide it in. and rotate it.
@@NickInTimeFilms exactly, I was gonna order but nothing's coming up anymore. Can you maybe try to contact him and ask? The upgrade is really worth it. Or get a list of parts so we could look them up one by one. Thanks Nick, Martin

NickInTimeFilms yeah I was about to say I never saw that in the FSM. There’s a np231d at my local junkyard so it looks like I might be rolling by there soon.
Not sure but can this be upgraded without pulling the transfer case? I put my super short say on that way. It was much easier than I thought it would be.
@@NickInTimeFilms I watch real close to see if the job couldve been done without removing tcase. So why does the tcase have to come out to do the planetary? Is it because the planetary gear has to go in the the backside?
@@randyanderson6110 watch after the 25:50 mark. There is a ring clip under the front cover that holds the splined input in place, which sits inside the planetary setup.
All this work you do and you’ve yet to get the other version transmission jack from harbor freight lol. They make a full v base version that is 1000X more stable and you don’t even need a chain.. the front and back of the top has tnuts so you can actually adjust tilt on the fly as needed.. that one I see you always using is a POS. Prob cost more to the other version you can use an impact to lift like a regulars scissor jack and last I looked I think they sell for like $59 lol. The rollers are shit but the jack is much better and easier to use and adjust on the fly.
Yeah, the 231 should be able to swap in place of a 242 or other similar case, but care must be taken to match the input gear so it will fit on the transmission.
Smashing upgrade, done like a pro :-D You missed a bit out........ pretty paint job :) Apart from the removal/replacement of the box, i think you enjoyed the rebuild, everything fitted together like a fine clock, but hit with a massive hammer ha ha :-D, Joke :) Good swearing, it shows that it made you work for your result :-D
Even though very long winded, EXCELLENT VIDEO. Short of the profanity....I put it on 2x speed and it is perfect. Thanks!
I love his antics and shenanigans 😂
Tack weld those carriage bolts.

What does this help with?
@@moejr14 spreads out the load on the planetary gear set and the wider chain/sprocket is stronger (1/4" wider)

How did this work?
What's it look like in there?
Motivation is key, when I put my case back in, I just picked it up and slid it in with almost one hand. I was fully surprised.
same did that to my girlfriends zj. yes they are heavy but if you got some muscle you can pop them out and in without a jack.
I remember 1989...good year when those came out!
IMHO, the best XJ is the last year: 2001
About time the 6 pinion planetary is the best, that was the first upgrade I did to my grand cherokee have fun...
The aw4 defiantly takes dex/merc but the t case it's safe to use atf+4. I actually did use the +4 for the t case intentionally because it's a full synthetic fluid. It's just bearings and a planetary set, no clutches to be harmed.
So now that you have the beefier components in the transfer case does that give you lower gears in the T case?
Nope, this is strictly about more meat on the components. Doesn't change any ratios or functions of the tcase
the s10 231 transfer case has everything you need to do this mine came out of a 95 s10 has the wide chain and the 6 pin planetary gear
Stubby gear wrenches are a good investment.awesome video.👍👍

Anyone still selling a kit like this? Not seeing anything but rebuild kits.

and clench your abdominals like you are taking a massive shit. protect that back!!
And ball's
Nice job Nick.Would love to see some footage of your Moab trip...
Me too haha. Time has been rather precious lately so trying to get everything done has proven tricky
@@NickInTimeFilms Question once I put the Sun Gear in planetary in case they won't turn.
Out of the case they turn very smoothly.
Any idea?
Just a fyi that synchro is ment for shifting on the fly
eBay link looks dead, but some of the parts are searchable but I don't see full sets.
That's weird, I can't even look up my order anymore. Wonder if he closed up? That's a shame because it was a great price.

@@MrDudeCZ @NickInTimeFilms any luck with the vendor? I'd love to find this kit! Also, great video!!!

paul kaufman that has ended as well
you also could have added the tera low 2 low kit. it gives you 2 wd low range
Also costs another $300. 2lo would be cool to have. But not that damn cool.
Keeping the CAD does the same. (Yes I understand it’s a weakness)
I can't find a 6 pinion gear for my 1990 231 J. By any chance do you know where to find them? I checked JB conversions and it says 1995 and newer.
Nick, use one of those horse shoe shaped wrenches, it makes this much easier.
So I know you said the aw4 takes the special fluid, but can you just use generic fluid in the 231?
Yeah, the tcase isn't picky, basically any pink stuff will do. I just use what goes in the trans for ease of service
NickInTimeFilms yeah I was about to say I never saw that in the FSM. There’s a np231d at my local junkyard so it looks like I might be rolling by there soon.
content suggestion --Azzy's t case linkage.or the Boostwerks kit.
Not sure but can this be upgraded without pulling the transfer case? I put my super short say on that way. It was much easier than I thought it would be.
You can do the chain upgrade in vehicle, but it's gotta come out for the planetary
@@NickInTimeFilms
I watch real close to see if the job couldve been done without removing tcase.
So why does the tcase have to come out to do the planetary?
Is it because the planetary gear has to go in the the backside?
@@randyanderson6110 watch after the 25:50 mark. There is a ring clip under the front cover that holds the splined input in place, which sits inside the planetary setup.
So here's my question when you upgrade to the 6 planetary gear does that change the 4 low gear ratio or does it stay the same
Nevermind saw the answer in another comment
Do the pinions in the planetary effect the low range gear ratio? (More gears equals slower) or is it just for strength
Nah, still the factory low range ratio, just spreads the load between double the gears.
I been waiting on this
That front input bearing is a pile of junk... You should have replaced it with a new one.
Wow sweet video! Very detailed as always. Hey where did you get that impact gun at? And how much? I’m looking to get one
Got it for christmas, but it was the 2861-22 kit, runs for $400
All this work you do and you’ve yet to get the other version transmission jack from harbor freight lol.

Devil's Nut...lol. Never touch it again!? C'mon now, it's a Jeep. You know you'll be touching it again soon enough. Hahaha
Painful, get to the point less waffling more work
Yay I'm first. So can a 231 fit in the same place as the BS all wheel drive transfer? Awesome job sir
Yeah, the 231 should be able to swap in place of a 242 or other similar case, but care must be taken to match the input gear so it will fit on the transmission.
Ratcheting stubby 😁
3rd and junkyard parts yea, finally my budget.
You can never have to many shafts
Smashing upgrade, done like a pro :-D
You missed a bit out........ pretty paint job :)
Apart from the removal/replacement of the box, i think you enjoyed the rebuild, everything fitted together like a fine clock, but hit with a massive hammer ha ha :-D, Joke :)
Good swearing, it shows that it made you work for your result :-D
Great job! Does the six pinion change 4 low gear ratio?
Nope, still the stock ratio
👍💪
I don't mean to sound like a "bro bra". I just lifted mine in by hand. Went right in.
Quit cussing the fasteners and get the right tools for the job, like a 72 tooth ratchet.
