Approximate cost of replacing timing chain and a rebuilt transmission

What is your question?

Had both things done at repair shop. Still not shifting right to lower rpms. I feel I was overcharged. $4550.00 total bill. I have to take it back in, not being happy the way it runs. Vehicle has 207,000 miles.

How long has your 2007 Saturn Aura had this problem?
