My Chevy makes a pitiful whining noise when I'm accelerating. Sort of sounds like transmission, because the pitch changes as the gears do. Suggestions?

Maybe something to do with the exhaust?

Your alternator will soon fail.. within a few months..
It may be putting out proper amperage but the brushes are worn.
Replace when time and weather permit.
Buy a rebuilt with a lifetime warranty..
This is a very easy job to do yourself on this engine..
Hint when you install the replacement put a little grease on the rear where the shaft ends( some tiimes this has a plastic cover over it).
This will make the alternator last longer buy keeping impurities out and not making the shaft wear due to inpurities.

Too little info, but I second the alternator theory.
