Transmission help/ question

Will a 95 SC 4R70W shift on its own without the connection to the wiring harness that goes into the transmisison connected? Leaving the connections to the MLPS, and other 2 sensors still connected. Obviously it won't start with the MLPS not being disconnected. I am trying to narrow down if it is an electronic issue or mechanical. I am thinking it won't, since the shift solenoids won't get any signals.

The main reason I ask is that mine will not shift into 3rd and OD. Just rebuilt tranny, new solenoids, all new clutches and seals. All clutch packs operated properly when air tested before installation into trans case. Shifts 1-2 great and I have reverse. All shifts are nice and firm and reverse engages quickly.

Been working with Dave D. looking for issues in the tune and can't seem to find anything wrong. Even tried loading a tune from the 2010 Shootout when the car ran fantastic and still the same results, no 2-3 or 3-4 shift.
