Issue:
I rebuilt my transmission 4T65E in my 2007 Impala. put it back in and put it all back together went to test it out and no crank no start. Noticed it says “features available in park”. No shift indication box on the gears.

Things I’ve tried:
Code read: 0
Re-adjusted the shifter cable. - actually put it in park still no indication
Made sure my grounds are all correct.
No Wires eaten by rodents.
Tried shifting in other gears with shifter and manually by the range switch.
Replaced every relay.

any insight would be helpful.

I have ordered a multimeter and a battery maintainer for further testing .

Things I think it could be
BCM
TCM
Failed NSS
Incorrect placement of NSS roller.

Anything else please let me know .

Edit

I just did a code read and this is what I got 30 codes. Can anyone confirm if this looks like it’s the BCM or is it the TCM I think it’s BCM but I saw TCM error once and thought w
Either the TCM is causing the BCM errors ot its the BCM causing both.
