Hello Liz, After you've tried the very sage advice already given (except getting rid of your Silver Shifters!), if you're still having problems perhaps you can look at the derailleur hanger and make sure it's not slightly bent.
Your ghost shifting in the 'highest 3 gears' is the opposite of my ghost shifting in the 3 lowest gear, but mine also occurred going up or cresting hills. In the end, I discovered that this issue was fixed when I diagnosed a bent hanger and straightened it. I also have Silver Shifters and these were definitely not the problem in my case.
