My car's clutch plates burned up on my four speed automatic transmission. Ok, it was my fault, I drove it to fast. Summit Transmissions' technician said that a re-manufactured transmission is less costly than to completely tear down and rebuild my transmission, because of all the loose particles from the burned out clutch plates. They replaced my transmission quickly, but about fourteen months later, a whining sound came from the transmission area. Since the rebuilt transmission was under warranty, they changed my torque converter on my transmission free of charge. I highly recommend their service for transmission repairs. Their service was quick, cost was very reasonable, and work was guaranteed.
