T-Case which one is it? LOL - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Timmy Berk · 08-09-2009, 02:29 AM

A friend gave me a 72 k20 with a 700R4 and a transfercase with no markings except what was molded on the case, dont know how to maintain it let alone use it LOL how do I figure out what I got?
Here is a pic of it...Anyone rcognize it?

bigbadchev72 · 08-09-2009, 02:33 AM

more than likely a 208 or a 241

Timmy Berk · 08-09-2009, 02:50 AM

Are there pics somewhere to reference it visually?

Igotachevyor2 · 08-09-2009, 10:32 AM

that gear cover in the middle tells it to be a 205
here is a linky http://www.chuckschevytruckpages.com/drivetrains.html

**Stocker** · 08-09-2009, 10:39 AM

Yup, it's a 205.

LONGHAIR · 08-09-2009, 10:48 AM

Yup, 208s and 241s were slip-yoke style and had aluminum cases...that big hunk of iron is a 205.

Timmy Berk · 08-09-2009, 10:51 AM

Oh man THANK YOU I went to check the fluid and it GUSHED out every where 3 miles from home last night and I didnt have a clue as to what to put back in... still dont LOL

**jerry moss** · 08-09-2009, 01:22 PM

regular old 90 wt. gear oil is all it needs, BUT, if the fluid "gushed out" you might want to take a hard look at the seal between the auto trans and the t-case. i had that happen many years ago with a 350/205 combo, t-case was way overfull and transmission very low.

Same thing happened to me. If the stuff that came out looked like it had ATF in it, well, that's why...

thats exactly what it is. After replacing one you question your sanity of "why do I do this crap"

I have another NP205 for sale in the parts section but if you need another one you can come and get this one for free. I aint' moving it ever again

powerdriver 1958 · 08-09-2009, 04:36 PM

That 205 is one tough transfer ................LOL I haven't broken mine and I know I treat mine rougher than most

If its overfull on lube the seal between the tranny and the transfer may be bad

And don't jump an atv ramp with out the extra t case support brackets,The transmission housing won't be happy

Dooley · 08-10-2009, 08:10 PM

205's came both ways. With or without slip yoke tailshafts.
Regarding 205 transfercase fluid,
My 1972 called for 80/90 gear oil.
My 1980 called for 30w motor oil.
My 1988 V30 calls for ATF.
They all work in a 205.

Eturnit3 · 08-12-2009, 01:50 AM

I once heard it said: "you could probably jizz in a np205 a thousand times and be fine, the just like anything thick n slippery" lmao

If George Costanza had only thought to tell his mother that his transfer case was low on oil!!!.

Not to start yet another lubrication debate, but would you recommend synthetic or dino jizz?

rangerfj40 · 08-15-2009, 12:03 PM

My rule of thumb for what fluid to use is based on the tranny. If its auto, I run ATF in the tranny and xfer. If its a manual I run gear oil in the tranny and xfer.
