You do need to break it in for 500 miles or so to get all the burrs out off the gears and to make it shift really sweet. Then, change your
oil and start smiling because your problems are now gone. Just don't power shift it like Godzilla and you should have a million miles of smiles. There is no need to beat up the equipment anyway. Life is too short to be fixing cars. Just treat them nice and smile while you DRIVE!
