Google says v12 came out in 2017. Current version according to Toyota is v17. Sounds like a new V/Yr. I want to say the one I used on my 2013 GS was 12, so I would suspect that is new enough For a ’11. Seems like in the obdIi tools, the trans temp pid has been a moving target, wonder if it’s under a different system or something in Techstream. Sorry, don’t have any better thoughts than that. On my ‘10 LX I have 2 trans temp PIDs that work, one for pan and one for TC temp. At least in the obdIi tool. I have never verified seeing that in TS.
Have you seen this thread? Easier wat to get trans temps than techstream.
