In the case of the transmission service my car required, I had already taken it to the dealer as well as another independent transmission shop for diagnosis. Both claimed it would cost more than $1700 to repair the transmission. I told this to the guys at A to Z and they said they would look at it and let me know. About a half hour later, they told me that they had successfully diagnosed the problem as a computer issue, not a mechanical one, and that it would only cost about $350 to fix the problem.
