Dude, you are coming across as an A-grade flog. Your original question not only lacked details, it lacked punctuation.
If there are untold details, and you are convinced of the repairs required, I’m struggling to understand why you need forum assistance, you’d be across who to take it to.
So far you’ve shut down all of the help.
If the converter is only two years old, I’d have thought you would contact the manufacturer of the torque converter and ask them who should do the work. Hopefully you’d be less of a flog to them on the phone than you’ve been to forum members so far.
