Is my car running too many RPMs?

I have a 96 Honda Accord Automatic V6. It has about 97,000 miles on it. Once it warms up, it runs about 2,800 RPMs at 65mph and about 3,000 at 70mph. It seems a bit high to me. Should I be concerned about it?

The final drive ratio is defined by the gears in your transmission. It is true that you might get slightly better economy and engine wear if the RPMs were a little lower, but the expense of rebuilding the transmission to replace the gearing would be more expensive than the benefit you can achieve. And of course, you could just drive slower to reduce the RPMs, perhaps you worry less if you drive 55mph.

That sounds about right to my, it depends on your gearing to what the rev's are at 70mph or 65mph the higher the gearing the lower the rev's. You should be just fine, in fact you should be in the power band at that speed so from 70mph if you put your foot down it will jump to 100mph in no time.
