Saturn Ion 2005 Clean Title

First, lease look at my ebay rating - I am 100% honest!
This car belonged to my mother for 10-years. She bought it new in 2005. All the miles on this car are highway - She drove from Arizona (home town) to family in Southern California nearly every weekend.
The car drives, ut it needs some work.1) Last week she noticed the car was not automatically shifting smoothly into second gear from first. Mechanic said a solenoid in transmission needed replaced. Because of the age of the car, e decided against any work
2) This has been happening for years with this car but never been an issue with performance. When the car first starts, here is a slight knocking sound coming from under the hood. We you press the car the knocking sound increases in frequency, ut after driving for a few minutes, he sound always goes away.
3) To remove the key from ignition, ress a button under the steering wheel.
