4x4 newbie needs help on ID plz - The 1947 - Present Chevrolet & GMC Truck Message Board Network

C20-67_N_MO · 11-02-2010, 05:16 PM

Okay I have a 1967 Chevy Suburban with a BoP TH 400 tranny and the transferr case has a silver tag on it.

My guess is a 205 or NP 205.

Here is what it has on it:

71 41 CTC

9 13 71 205

Let me know what I have please.

Thanks folks!

I would guess it is a 205.

C20-67_N_MO · 11-02-2010, 09:01 PM

What does the NP suppose to mean on these things?

Anyone know that much?

Davidmichael · 11-02-2010, 10:52 PM

NP= New Process, as in the company that manufactured these transfer cases- New Process Gear.

Take a picture of it, or even just the case itself. It should read like the following:

model X XXX ratio xxx
serial x x xx
Assem. no xxxxxxxxx

Cool. Thanks!

Still in the process of cleaning her up.

on the heavy part of the case is has C-99404 and on a very small tag has 7-20-71, which I am guessing is when it was made.

More later once I get that heavy thing cleaned up.

Thanks guys for all your help.

I know C-99404 is stamped into the cases, but do not know exactly what it means.

C20-67_N_MO · 11-03-2010, 07:38 PM

Want to put in new gaskets and seals while it is apart, how easy is this?

Davidmichael · 11-04-2010, 08:39 AM

I have never done it, from what I can see, it's pretty straight forward. Check the gear oil when you drain it for metal shavings, check all the gears, and then replace anything that needs replaced including the seals. Fill it back up with the proper oil. I always use stuff from royal purple (big $ but worth it IMO)

C20-67_N_MO · 11-04-2010, 12:55 PM

Good advise - Thanks man.

Do yoursepf a favor and use the search feature here for NP 205 and or Transfer case, its been coverd a bunch of times and good info posted.

Also do a google search, both Web and Images for NP 205 and NP 205 rebuild kits.

C20-67_N_MO · 11-09-2010, 04:14 AM

Only thing I came up with is from Monster Transmission and just the gasket set is $70!

Rebuild is something like in the mid $200 or so which seems fair.

Might as well just have my tranny guy go thru it and make sure it's okay before proceeding.

swamp rat · 11-09-2010, 04:31 AM

I suggested google images so you can see pictures of the NP205 and make sure thats what you have, the NP203 looks a bit different.

Parts can be a bit expensive, you can allways start with a napa store too. but heres another link.

Those prices are absolutely ridiculous. Much better price at the link below.

OP, in your identification, look between the rear output and the front shaft's rear bearing retainer. If there is a little 3-bolt cover between them, it is a 205. If not, it is a boat anchor.

Now your talking!!

Thanks guys!

I had my NP208 rebuilt at a local shop in April.

New seals, bearings and chain. And of corse labour.
900 beans later.

Reman case is 1200 + tax. (after core return)

When I blew the 4spd in my truck I drained the tcase fluid for removal and it looked like pink metal flake paint.
Chalk full of partical goodness. /sigh
