I have an 07 New body style vmax 6.0 and I am having some problems with reverse. Reverse work fine if I don't give it much throttle, but if I do get on it a little its like it pops out of reverse and makes this loud winding noise. I have taken it to the chevy place and they said they could not find anything wrong with it and there were no error codes shown. I'm stumped. Any help would be much appreciated.

Thanks in advanced....
