Need new Tcase

[Magnum44357]

Hey, really really long story short... I need a new Transfer case...

Currently I have a Np208

suggestions on a different model of case? or is a 208 what i should have?

should I get an old used one and have it rebuilt?
or should I buy one already rebuilt?

tips on things to look for when shopping?

I'd like to stay as cheap as possible...

Trucks is a 1973 K10 (used for wheeling mostly keep in mind)

anything helps guys, thx!!!


ps. Heres one I've been eyeing up today. and also a link to a pre-rebuilt one (good, fair price?)

id have to say it depends how bad you messed it up... you might be able to rebuild it cheaper than buying a new one... or get one cheap off CL if you want to gamble having to do the job again... 300 and 450 seem a little steep to me, could be because i run 203/205 and have never paid more than 100 for one... the $450 one does look pretty clean though


73's didnt come with 208's right? i was thinking it would have been a 203 or 205 oem

heres a 208 near me $50

Sometimes we need more info to help a person out, or give advice. In this case, need to know which trans you have. Many guys will put in the profile where it says engine, 350/Th350/NP208, then we know you have a 350 motor, a Turbo 350 Auto trans, and an NP208 Tcase and know what you're working with.
Obviously the NP208 you have now, no matter what trans it's behind isn't original. All 73 models came with NP205 which is a Cast Iron case and is gear driven isntead of a chain. It would be nice if you can find one of those to put back in if you wheel often and hard. If we knew which trans you have, then we could tell you which one to be looking for. If you just want to go back with what you have and not have to worry about shifter modifications and driveshaft mods, then you can go with an NP208 or even an NP241C that is also aluminum case chain driven like you have now. It's just got a hair deep crawl ratio. THere is also the chance depending on your trans, you might not have to mod much to convert to NP205, but you're alot less likely to tear up an NP205.

OH, and $300-$400 is to damn much for an NP208 if it's used. I find them here all the time for $50-$75 and usually $100. I paid $25 for one and grabbed it just cuz it was cheap and didn't need it. It came with the adapter too. The adapter alone is worth the $25.

 

[Magnum44357]

Gotcha, Thanks for the responses.

You are correct, it is not stock. My truck was originally a C10 with 3 on the tree but converted to 4x4.

The transmission is an Np833 hooked up to a 350sbc

Its not my daily driver so I dont mind putting some trial and error work into it to make a diff setup work too btw.

got any recomendations for a whole new setup? diff tranny and all? I feel better putting more work into a nicer build than just replacing the tcase and running into problems later.

Thanks

 

[crazy4offroad]

I'll take that ole piece of **** A833 off your hands!

 

[HotRodPC]

BAMM, that makes member #4 with an A833 now. I don't care your Tcase is broke or not. I'll take it. I'm looking for a Tcase to fit my A833 so I can get it installed. Not sure why you'd want to get rid of the A833, but there are certainly a few that will take it off your hands if you don't want it.
You'll need a 32spline female input NP208, usually off of a Th400 or later model SM465 manual trans. I will settle for an NP208 that will work, but I really want a Round pattern NP205. Some mods have to be done to make it work, but it can be done. The other thing you can do, to make it easier, since you have the Tcase, KEEP IT, don't get rid of that thing whatever you do, unless you give to me of course, but if you find a good much more common NP208 from a 700r4, you should be able to swap your input bearing, (or buy new) and 32 spline female input shaft into the 700r4 Tcase and make it work. The 700r4 Tcases are the ones you'll find for cheap, like $75-$100. I should have bought the one that was married to my A833 for $75 but at the time, I didn't know it was a Th400 instead of 700r4 and I have 3 NP208 for 700r4.

They have just been coning out of the woodwork lately, haven't they... except for around these parts.

 

[HotRodPC]

So we have 2 trucks that are original A833 trucks, and he'd make the 2nd member that's gonna have a retrofitted A833 truck. All are cast iron 4x4 trucks too.

In other news, you know you can buy full rebuild kits for these transmissions. The 4x4 model kit comes with a new countershaft, but the 2wd model does not. There is a difference in length between the 2 so they don't interchange. Makes me wonder, does that mean the 4x4 tears them up, or just that it's no longer avaible for the 2wd unit just because it's not available. It might be that the 2wd unit uses a GM only countershaft since GM is the only one that used aluminum case, and that the Mopar countershaft does fit the 4x4 cast iron unit.

oh lol well see, I know very little about transmissions, I didnt realize it was rare :O

the reason I believe I need a new Tcase is because I found a very large crack on it. the crack had drained the oil completely out of the case and when I went to change the atf fluid last week I came across a cup of water and metal shavings... currently it still runs great, but I kinda was hoping that 200 bucks would just buy me a newer one without oil leaks to worry about...

what u guys think? try to patch the big crack and run it till it dies? or "upgrade" to a new one?

that all said I wasn't sure if my tranny was up to par for wheeling. what makes it so desirable by you two anyways? haha

 

[HotRodPC]

NO, you're not using that tcase. You need a new/used one. BUT, like I said, don't trash yours. It's pretty tough to find the one you for that trans. As said, you'll need a Tcase off a later model Th400 or SM465. One that has the short female input. I think that's the only way the 32 spline comes in a NP208, but still, if you can find one, which should be pretty easy, for a 700r4, then swap the input shaft and bearing out of your current Tcase into the 700r4 Tcase and it should work fine. If you're willing to spend $200 on it, then I'd say find one for $50-$100 then buy you a gasket kit or maybe even bearings and gaskets and make it almost good as new again. It's possible your old one broke because a bearing wore out and a shaft got cattywompus in the Tcase and caused the break, or that you got on it hard and broke the Tcase. Good to hear the Trans held up over the Tcase though.

Yes, the trans is rare. Seems it was special order only. Haveing an Overdrive is the big plus. 700r4's are known to be weak and fail often. This trans is almost the same identical gear ratios as a 700r4. Technically it is the same, you wouldn't notice the differences being they are like .03 and .05 in 3 gears. They may not be as strong as an SM465 or NV4500, but they are certianly stronger than the 700r4. Being side shfited transmissions and not top loaders, they can also be speed shifted if you really wanted to, and they come with a factory Hurst Shifter too that makes them pretty cool too. I'm hoping to find an NP205 round pattern Tcase to put with mine, but its gonna take some grinding on the trans to make it fit since it's not an OEM match.

 

[crazy4offroad]

what makes it so desirable by you two anyways? haha

0.73:1 overdrive! Without having to spend a fortune to make it work like you would with an NV4500 or 4L80e! If you got low range IMO the trans is fine for wheelin. Maybe not bumper-to-bumper tug-of-war contests or silly **** like that but it's a trans you could run a deep final drive, but still have a decent rpm driving it to the trail because it has overdrive.

 

[Magnum44357]

oh wow nice! guess I'm keepin it Crazy... sorry...

I found this on CL. the guy sais there both np208's (which they look very similar) would that happen to be the differences in short female shaft your talking about?

http://seattle.craigslist.org/kit/pts/3162764097.html

just by picture comparison, my current np208 looks exactly like the one in the bottom picture. wouldnt happen to be the exact on i need would it? haha

I'll have to do some reading up on them here tonight.

 

[crazy4offroad]

If you have the t-case out of your truck the main thing to consider is the length of the input shaft. Measure yours and then see if the guy will measure one of those and then you'll know for sure.

 

[HotRodPC]

Yes, that bottom one does appear to be the exact one you need. Notice the input shaft is bigger around than the first one. The first is for a 700r4/Th350, and that second one appears to be the Th400 input. For $100, there you go. Rock On with it !!! And if by chance it isn't the one, then you just change your input shaft and bearing into it and it's now the right one for sure. I'd be calling before he sales it. You might even hit the guy up for $75, but $75-$100 is the most common seen selling price. As said, I've got mine for cheaper than that, but that's just a matter of finding someone desperate and I didn't need it, just bought it cuz it was cheap. You're in need right now, so $100 isn't bad, but I'd still shoot for $75. I"ll sell you one for $75. So go tell the guy you can buy one for $75, but his is closer and if he'd match it, you'll get the cash in get right over.
