Your right I don't know what exactly happened in this case but I do know by reading your post that you have made statements that are untrue. I would like to know how you determined the wrong flywheel was used without taking the tranny off the motor and inspecting it?

People bash good shops and give them a bad name. If you have a problem with the shop then deal with them and finish with them before you post about how bad they are. Most of the time they will fix the problem or at least work with you. If you came on here and bashed my shop without allowing me to look at the car then I would tell you to go fuck yourself too.

I guess what I am trying to say is I am tired of reading posts bashing shops when in the end the shop either did the job correctly or the problem was minor.
