Thats good to hear you got it going good.
Most tranny shops are in bussiness to make money, lots of it quick and easy, that is the reason for all the hesitation from most shops. Once in a while you will find those in bussiness to provide a legitimate, truthful service to repair transmissions for customers. The difference is what comes first: MONEY (which = greed) or Passion (which = honesty and drive).
Now what you can do is get some tuning software and fine tune your transmission to how exactly you want it.
