Local flush or send converter back to Yank??

Mike knows what to look for and how to inspect his products. There isn't even a question in my mind on that one. You can pay a local shop to do it, and if something isn't right with the converter, either A: they will find it, and you will be out that money PLUS the money to Yank to fix it, or B: they will not find a problem with it, put the converter back in the car, and destroy your brand new trans. Oh, and you'll STILL have to send it back to Yank for service.
Looks like I will be giving Mike a call next week.
