I dont know about newer cars, but I brought in a 1967 mustang i had recently purchased. Tranny ran great except for a metallic sound. Village Transmission diagnosed poor install fixed it. cost me $1000. went to pick it up, now the transmission slips. Thier excuse...broken motor mount. I'm no dummy but that makes no sense. but to be fair before i complained i fixed the motor mount, Amazingly still slips! Took it back, they put in some aftermarket tranny fix from a bottle which did little to help then offiered to charge me another $100 to change the fluid fix! The record reflects that originally I told them it might be better to just rebuild it when I first brought it in but they said we dont recommend rebuilding unless it definatly needs it. Well duh, after your initial fix for a grand, it still needs it. I am sure if i brought it back for the rebuild they would happily charge me another grand. signed... should gone to someone who works on older classics
