Invalid trans PIDs (i.e. gm.gear) e38/t42

[bubba68ss]

Trying to view trans state PIDs (GM.gear, gm.prndl, gm.tstat, etc) and I get them as invalid. Red X. I connect as e38 with trans checkbox ticked. It's a 2007.5 Silverado 5.3. Also commanded AFR is red x'ed.

What am I doing wrong?

I am also having same trouble, and yet last week these were working fine, until I got an error trying to relink
I then read warnings and had a $31 (from memory), and selected as instructed Shift f2 which validated things, and the lost many of my PIDs
Attached is a screenshot of my trans pids19215
I have never been able to grasp the logic for these Dashboards...... and dont worry I have used it 1000's of times..... and have written here before regarding this, and am reluctant to save dashboards because it invariably stuffs everything up, and then you need to scratch, reload and start all again, which costs countless time.
Its always been a fingers crossed situation everytime I use it, and sometimes just simple things in LS1b PIDs like Dynamic Airflow becomes invalid,... which is real handy, considering it is the PID to track spark, which is one of the MAIN requirements needed......
I have read and re read the tutorials, and anything I an find, but if the PIDs aint there how do you revalidate them???
Any help on this much appreciated and maybe a new sticky to help inexperienced newbys with this.

Is this only with V7 scantool, or is it also with V2 BBL and V8 scantool...?

Is it possible you were connected to the ECM and not the TCM when you validated those PIDs? The valid PIDs look like ECM PIDs and the invalid PIDs look like TCM PIDs.
