I have been a customer of Santa Rosa Transmission since 2005. Sam and his team have installed clutches, serviced transmissions, differentials and transfer cases on my vehicles. They have resolved problems with errant shifting of my automatic transmission and an issue with a limited slip differential. I have recommend them to MANY people and I have never had anyone tell me of an unpleasant or unexpected experience. My example is a Ford F-150 4x4 with 160,000 miles and that dreaded AOD transmission. I have heard from other owners that theirs have failed, they have already replaced their transmission, that it was expensive, etc, etc....Mine is the original transmission, has never been rebuilt, it is still going fine - which I credit to regular maintenance by Sam and his team.
