Sam helped me with the transmission. I was hesitant if I should replace it as my car had 100,000 miles. He worked with me. Thank you-

Sam and his team are wonderful! He is honest, fair and will go out of his way to find the best solution to any issue your car may have. Sam is courteous and generous, and I highly recommend Golden Gears. I teach at a school nearby and we ALL take our cars to him. I just picked up my car from his spotless workshop, and Sam found a cosmetic flaw which he fixed on the spot, free of charge. Golden Gears is a treasure.
