Awesome! I replaced my Camry 2017 transmission in October last year. Recently, I felt same problem happened such as vibration at low speed. So, I thought this would be transmission problem again. But, after test driving by Sam with computer diagnosis, it was not the transmission problem. It was some sensor(fuel injection to transmission) problem due to carbon residue. It was cleared after several hours and the problem was gone way. It is really nice experience and thanks to Sam and his team. They are real! Thanks.
