Upper connecter has 8 pins.

It's a 46RE then. (And it has the bulge out where the stick goes) and the 42R's don't.
42's are 904 variants and 46's are the 727 version.

So, can I use this trans in a non-computer controlled engine environment - or shift it electrically - with a manual switch? Tunnel mod for the OD is not a problem. I have the computer ( marked 96 Dakota 4X4 ? ) and associated wiring, but the wiring is pretty hacked up. Considering running the engine as a non-computer engine, but with the electronic trans so I can have OD.

No you cant use it without a computer and all the associated speed sensors and stuff unless you buy a trans controller (which are available)
Tunnel mods are pretty extensive for the 46's and up.
