My 2005 Corvette developed a small oil leak somewhere in the rear axle. As the transmissions are located in the rear of the vehicle and integral to the rear axle - I didn't want to take a chance by not attending to the problem. I was concerned if one failed - it would cause the other to fail an become a prohibitively expensive problem to repair. Dave in service looked after the problem for me - fully explained what was going to be done, showed me the cause of the leak and had the job finished sooner than expected. It wasn't a cheap job to have done - but I know it has been done properly by GM mechanics and have the confidence to drive the car without a drive-line failure. Thank you Dave and crew.
