Radio/tape Cd Player problems of the 2011 Chevrolet Malibu

On November 1, 2017, while driving home on the expressway I hear this loud revving noise, I turn my radio off and realize it is my car making the noise and than the check engine light comes on. When I was able to I pulled over to the shoulder and turned my car off in hopes of the error clearing out. After a few minutes I turned the car back on only to find that the check engine light was still on, when it was save to do so, I pulled back into traffic with my hazard lights as I could not go over 20 to 30 mph without the rpm going up. I made it home, tried to back into my garage only to find that my car will not go in reverse. I put the car back in drive, pulled around to the front of the house and parked the car. Since it was after midnight, I called Chevrolet the next day and the only thing they could help me with was to get in touch with a dealership to schedule an appointment to take the car in for diagnostics as my car was no longer under warranty and there is no recall on this model year although there is a recall for models 2007 thru 2009 for the same issues. My service adviser called me later that day to tell me it was due to transmission failure, they found metal in the transmission and his advice was to replace the transmission. My diagnostic code was p0776( pressure solenoid 2 stuck off), my bill $3946 for car that has 84000 miles on it. A car that I am still paying a car note on. When I purchased it 4 years ago it had just under 30000 miles on it. I have done everything to maintain my car because my biggest fear is being stuck on the side of the road, especially since I am a woman working 2nd shift. I do not have my repair invoice yet as I have not picked my car up yet, its not so easy to come up with nearly $4000.

At random when driving down the road the radio will switch to aux. You can touch the dash on the side or around the radio and it will go back to radio. It will also switch sometimes when you put the car in drive, or turn on windshield wipers. You have to bump the side of the dash or the area around the radio for it to switch back.

The rattling or knocking noise that is heard in the front on the drivers side really bothers me that something is ready to fall off or break. In October of 2012 I also had to replace turn signal lamps on the driver side rear I wouldn't think they should go out that quick.
