Hi Guys,

I know the early M37 transmissions are called New Process 88950 and the B1 version was called New Process 420....but was was the Transfer Case and both Differentials called?

thanks,
bob

The transfer case is a New Process Model 200 (NP200). The Diffs were just Dodge as far as I know. I'm not sure what number they had.

Hi K8,

Thanks for the info. So what I know so far is the Transmissions were NP88950 or NP420, the Transfer Case was NP88845 or NP200, and the differentials are Dodge full floating hypoid with the front diff being called a New Process Tracta Drive. I think there's more to know about the differentials, so I'm going to find the casting numbers when I get home and see what I can gleen from them.

thanks,
bob
