No, your transmission is a lemon...not your car. I don't know if this falls under the lemon law, you might want to do some research on your own.

Honda has diagnosed and fixed the transmission problem. All transmissions as of like last fall are fixed and will not show the symptoms of sudden downshifts and other things that you described. I would give your 4th transmission some time...1.6% of transmissions turned out to be faulty, you must have a mark on your forehead or something But hopefully the new transmissions that are being manufactured trully are fixed.
