Click on the link. I tried to get everything on one page, which makes it harder to read. It's been my experience that posting multiple images, only the first image posts, not the others. I didn't see a relay in diagram.
The bcm controls door locks with input from the door lock/unlock switch, I doubt I can trouble shoot that from here. You could check for bcm trouble codes, see if anything comes up? Some of the national brand auto stores will check po codes for free, I don't know about bcm codes?
Could be other issues.

the transmission shifting problem indicates that the vacuum hose and vacuum actuator have a problem as that unit changes ratios when the vacuum is correct
have the battery load tested as the other problem could be low voltage affecting the performance of the ECM
have the fault codes read
also check for a bad cat converter as it may be blocking the exhaust system

In the I/P fuse block, check the 10A RADIO FUSE, the 2A STR WHL CTRL FUSE, and the 20A RADIO AMP FUSE. The steering wheel controls also may be the source of the problem.

The system only activates like this if there is a defect in the systems operation, you must have the security system scanned to see what is causing the unwanted activation. This is a dealer level repair.

Check the fuse links for bad connections. There is a you tube video that shows you how to repair them Just search for automotive fuse link repair.
