Um i think you answered your own question there. One is a NP 231cHD and the other one is a NP 233c.

I am looking for the chevy names. When was the last time you called a 700r4 trany by its manufacture model #.

There are no Chevy names for them.New Process Gear makes t.cases for a few differnt auto makers.

When I repair or replace a t.case,I always use the model# for reference when ordering as does anyone else I know.Even at the dealer.
