Forgot to answer to your question regarding TechStream; this is question is in advance:
As far as my car, I did not do any CVT calibration as it was not needed (due to fluid change only).
However, I did the CVT calibration of my cousin's Grande, whose CVT Fluid pan was opened (23-Jan-2019). We used TechStream.
I did calibration of CVT of another Toyota Vitz 2005 whose CVT was replaced.
Both calibrations were done via TechStream and I will elaborate the procedure (by the way using TechStream might require starting another thread).
