Identifying a 4-speed Chevy Trans????

[1994 Python]

I have a 4-speed chevy trans that has been setting under some shelves. I can't seem to identify it. On the right side of the case it says DNE with 71-80024. I know this should identify it as a 4+3 trans, but it has a tail section with no overdrive. The numbers stamped into the main case are 1GS111871. Any help you can give me would be appreciated. Thanks, Judd

Crack the case and see what's inside. Post some pictures. I believe the DNE 4+1 had all forward gears in the main case. It is not an over drive trans. 5th is 1:1.
