Tcase identification - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Mario Cerda · 05-19-2005, 08:17 AM

I need your help in order to identify a transfer case. I found this tcase under a 1965 or 1966 GMC pickup. Initially I thought it was a Rockwell T221 or a Spicer 23 but it is not.

Thanks in advance,

Looks like a rockwell T211 Divorced case to me. My buddy had one in his 66 3/4 ton chevy. Later models had married cases. Might be a dana 20. I've never seen one of those.

Rockwell would be my guess, my fathers 65 K10 has the Rockwell 221..

Rockwell for sale here, (not mine) does it look the same?

Identified !!! is a NP202

. I suppose the original tcase was swapped by the NP202 sometime.

The rockwell T221 tcase looks really different, take a look at the following pictures of a Rockwell Tcase:

Could it also be a NP200?

Impossible... the NP200 has as second output on the rear used for the parking brake. Also look at the position of the shifter rails, in the NP200 there are parallel to the top of the tcase.

What is an NP202 out of?

**JIMs70GMC** · 05-20-2005, 08:15 PM

Forgot about that, I know the NP200s came in the M715s.

How about a cast iron NP203?

Mid 60's IH transfer case. Tough but not many around. It's similar to a NP205.
