Toyota Repair: transmission flush, 6 cylinders, auto transmission

Question
Hello.  I have a 1999 Camry w/auto transmission, 6-cylinders, 47,000 miles.  I'm going in to a non-dealer for a transmission flush. How can I be sure they do the whole procedure and not just change the fluid? I am not a mechanic.
         Thanks, -J.S.

Answer
If they let you in the shop to watch how they do what they do then great, if their policy is not to do so then there is no way to know what what procedure or machine they are using, maybe you can ask them to let you see the equipment they are using before having them do it.
