except for the not being able to give an estimate, that second shop sounds VERY GOOD. no shop around here (except maybe performance shops that probably wouldn't touch my tranny) would encourage use of sythetic ATF. I like that part about them using what is best for tranny not just any ol' kit. i'd go with them, but ask them what it would cost if your tranny can be rebuilt or if they need a new case or whatever u were saying.
