speaking of which, does anyone know a good place to find them for cheap or have one for sale for cheap, they get scavenged too fast in the junkyards down here, and mine is leakin like a civ, and won't disengage fully. So it's time for a new one.

ok from what i can see it is a 203 fulltime now i have heard that these transfercases are weak is this true?
Title: Re: transfercase
Post by: 85MudMonster on January 30, 2009, 04:59:18 pm
from my understanding the NP205 is the best then the NP203 then the NP208 (which I have)
Title: Re: transfercase
Post by: Captkaos on January 30, 2009, 09:13:44 pm
It depends on what you are doing to it. 
Weak for a 1000hp Mud truck, yeah.
For a healthy daily driver, no.
Title: Re: transfercase
Post by: hotrod24 on January 30, 2009, 09:53:05 pm
 well i would like 350 to 400 hp but i want be doing any wheeling so i am good there but only thing i will use it for is to get up the drive way or to get to town if it snows so i guess i am good
Title: Re: transfercase
Post by: Captkaos on January 30, 2009, 10:03:12 pm
I personally would want Overdrive, but you would probably need an adapter for it on the 203.

Post by: 85MudMonster on January 31, 2009, 12:16:36 pm
for swapping out to a new trans go here for the adapters:

Title: Re: transfercase
Post by: Captkaos on February 04, 2009, 06:11:42 pm
Part time the 203, find a 205 and make it a doubler. 
What are you going to do with the truck?  Daily Driver?
Title: Re: transfercase
Post by: hotrod24 on February 04, 2009, 06:38:42 pm
 daily driver and no off roading just mostly a show truck and a driver
Title: Re: transfercase
Post by: Captkaos on February 04, 2009, 08:58:26 pm
NP208 will be more popular, quieter, easier to find and already be part time.
Title: Re: transfercase
Post by: hotrod24 on February 04, 2009, 10:29:04 pm
what all would i need to swap to put a 208 in?
Title: Re: transfercase
Post by: hotrod24 on February 05, 2009, 12:51:15 pm
i wanted a fresh start so i restarted it so now it is the 203 with kit or 205 or 208

thanks
Title: Re: transfercase
Post by: Captkaos on February 05, 2009, 04:24:45 pm
I would go with the milemarker kit and then upgrade when you can.
Title: Re: transfercase
Post by: VileZambonie on February 05, 2009, 04:32:11 pm
find a parts truck with 700r4/208 and go that route.
Title: Re: transfercase
Post by: hotrod24 on February 05, 2009, 04:46:34 pm
hmm the 700r4 and the 208 does sound good and i would do the mile marker kit but this truck is going to be tore on down and built back up so i am hoping that i want have to upgrade for a long while and i have called around and the 208s and the 700r4s are popular around here but there is few 205s so i will just have to see.

thanks
Title: Re: transfercase
Post by: Captkaos on February 05, 2009, 04:55:33 pm
If you are tearing it down and replacing stuff.  I would have to agree with Vile, get a 700R4/208.  They are far less favorable among hardcore people so "normal" people think they are junk and devalue them, so in the end you get a great deal on a setup.
Title: Re: transfercase
Post by: hotrod24 on February 05, 2009, 05:05:34 pm
yea i can see if i can find a 700r4 and 208 set up but it looks like the 205 is winning lol
Title: Re: transfercase
Post by: hotrod24 on February 06, 2009, 09:33:50 pm
ok i have a 383 that i will be putting in and i will be swaping for another transfercase and tranny but right now i have a th350 and a 203 tcase so if i was to get the th400 and 205 what would i need to get from the parts truck?
Title: Re: transfercase
Post by: joesgarage71 on February 07, 2009, 09:58:54 pm
 Crossmember, torque converter, both driveshafts, the Alum.400 conveter cover with the two strut arms, the trany lines, dip tube and the vacuum line(manifold to modulator) The gas pedal assy.with switch and the wire from the switch to the transmission. any and all the attaching hardware.
Title: Re: transfercase
Post by: hotrod24 on February 07, 2009, 11:46:55 pm

Good parts truck will have everything you need.
Title: Re: transfercase
Post by: hotrod24 on February 09, 2009, 02:04:46 pm
yea i have to check one junk yard and if he does not have a truck then i will have to check a few more but i am hoping that one of them has what i need
Title: Re: transfercase
Post by: 1976Scottsdale on February 10, 2009, 10:26:33 pm
I always liked my 203's as full time.  The kit saves some mileage, but not a great deal and it does cut down on wear on the front axle, but again, go through the frontend and replace the joints and put in some good greasable ones and service them when they need it.  Course, I like the front drive flanges... when its time to play I just drive in rather than get out and lock the front or hope the auto hubs work, my stuff is tied in forever.

i just dubble checked and i have holes for a skid plate on the passengers side but not the other side i was thinking that maybe it was just on 3/4 ton or 1 tons
Title: Re: transfercase
Post by: cracker0169 on February 16, 2009, 04:32:18 pm
I have an extra factory crossmember, and I have considered bolting that as shown and mounting some steel to it. With my truck being a long wheel base, I would hate to tear my 205 up if I got it high centered!
Title: Re: transfercase
Post by: hotrod24 on October 24, 2009, 12:24:52 am
can you bolt up a 205 to a th350?
Title: Re: transfercase
Post by: Donut on October 24, 2009, 06:03:56 am
Yes, (that's what 's on mine)  You just need to find the transfer case with the correct input shaft.  Don't quote me on this, but I believe the th350 was 27 spline, and the th400 was 32.  If you are going to do more than putting a part time kit into the 203, personally I'd be looking for a parts truck.  You'd have the trans, transfer case, adapter, crossmember, and driveshafts if you needed a different length.

If cost is a factor, I wouldn't discount the 203, how many years did it run in your truck before the teardown?
Title: Re: transfercase
Post by: hotrod24 on October 24, 2009, 11:39:07 am
ok good i have a th350 just need to find a 205, would i need the 203 for this at all? and yea i have been looking for a parts truck but i did not ever drive this truck it sit most of the time
Title: Re: transfercase
Post by: Engineer on October 25, 2009, 12:04:17 pm
The NP205 is worth every penny.  :)

I have seen these things hold up to some pretty radical 4x4 truck pullers with out fail.

Also, I didn't see it mentioned yet, but the NP205's ID tag is on the front of the case underneath the 2 shift rails.

It is typically a square piece, especially on the older models, and not round like all of the other NP/NVG t-case models.
Title: Re: transfercase
Post by: thirsty on October 25, 2009, 01:42:37 pm
I just realized a week ago that there is a difference in input shafts for the np208. I had a 81 208 that was behind a th350 and the shaft was smaller than the one behind my 4 speed. Make sure you get the right one for whatever trans you decide on. Whole parts rigs are the best.

I put a mile marker kit into a 203 about fifteen years ago. I can't remember the particulars but it was easy, worked perfect, and I used that truck for mud bogs. Never had a problem with that 203.
Title: Re: transfercase
Post by: beastie_3 on October 26, 2009, 09:44:51 pm
My transfer case looks like the one in the pics on the first page, so that would be a 203. Would it already be converted to part time if I have manual hubs on the front axle?
Title: Re: transfercase
Post by: thirsty on October 30, 2009, 07:17:50 pm
If it isn't than you would have to have the 203 in either hi-loc or lo-loc to move the truck.
