check out example win sdk "wilstxfm.vbs". on system it's installed @ path:

c:\program files (x86)\windows kits\8.1\bin\x64\wilstxfm.vbs 

can't paste code here because of copyright issue, this:

database = installer.opendatabase(msipath,0)  database.applytransform(mstpath, iteviewtransform + iteaddexistingrow + itedelnonexistingrow + iteaddexistingtable + itedelnonexistingtable + iteupdnonexistingrow + itechangecodepage) view = database.openview("select * `_transformview` order `table`, `row`") 

then iterate on records of view print changes transform do.

you should able translate .vbs sample powershell code or call .vbs script ps.
