Brought in my 2013 Ford Focus SE with transmission trouble. Dave and Julian confirmed a clutch issue fast, walked me through what’s going on, and outlined options without any pressure. Clear communication, firm handshake, zero gimmicks. If you want a straight-shooting transmission shop in Napa, this is it.
