Thank you for your prompt replies, I will advise the repair shop of your evaluations & testing procedures they should have done from the beginning, and will keep you updated with the results.

I have a bad feeling the repair shop is jerking me around on this problem, and are not being forthcoming as to the diagnostic procedures, if any, they’ve were suppose to make prior to changing expensive part at will.

I believe they have discovered their mistake and don’t want to incur additional cost in correcting the ASR problem. But one way or another they will either repair the problem to my satisfaction or refund me for repair cost I’ve incurred so far.
