George Hallahan and his service manager Julio do an amazing job. Had a noise coming from the transmission of my truck and called George and he told me he felt it was a rear or suspension issue. I brought the truck in the diagnosed the problem was in the driveshaft and it was sending the noise through the transmission. Rebuilt and rebalanced both drive shafts, problem solved. Transmission makes no noise and saved me thousands of dollars from replacing the transmission.
