EDIT If you're looking for the the secondary boot loader file CC1T-14C097-AA.VBF for your tranny...
I used this process: https://www.focusst.org/threads/how-to- ... 22.170004/ but the downloaded file as per instructions was in ASP format, not VBF.
What you need to do is paste CC1T-14C097-AA.VBF (yes, WITH the .VBF extension) into the box on the 'Download Files' screen
A download of a ZIP file is prompted. Download it wherever you want.
Open the ZIP file and you'll see the VBF boot loader file.
Unpack the VBF file and save it to your "CalibrationFiles' folder (there'll probably be a couple of other VBF files in there too)
Hopefully that's useful. I spent ages trying to find it and originally this post was asking for help, before I stumbled on the solution randomly. Thought I'd post here to help others. Hope that's OK
