I have a 2007 Honda Accord with 77,000 miles. Recently, it began shifting just a shade hard. This would occur only when shifting from 1 to 2 and from 2 to 1 (when coming to a stop). It wasn't a huge deal, but it certainly wasn't a good sign, either. I had the transmission fluid changed, and I added three ounces of this product (Lubegard directs you to add one ounce for every liter of transmission fluid, and the Accord takes three liters). After about 1000 miles of driving, the hard shifting has all but vanished (it took a while, but it's slowly going away).

Tip: Another thing you can do is disconnect your car's battery for a few hours. Sometimes this helps, because it resets the car's computer, and since transmissions have electronic shifting nowadays, this MAY assist or fix the problem. I'm not sure if this helped in my own scenario, but it certainly didn't hurt, and it's something you can easily do yourself in just a few minutes. Just disconnect the terminals, let it sit for a few hours, then go put them back on (you'll have to reprogram your clock and radio presets).

Of course, the best course is preventative maintenance. Be sure to have your fluid changed (NOT FLUSHED- this will just blast the foreign particles throughout the gears of your tranny, creating more problems) every 30,000 miles or so. This only costs about $70, even at a Honda dealer, which is a whole lot cheaper than a new transmission. Getting your transmission fluid changed on a regular basis is particularly important with the Accord (and other Honda models, I presume), because the filter CANNOT be reached or changed (unless you remove the whole transmission, which nobody in their right mind is going to do, at least not without charging you a fortune). Good luck... and take car of that tranny!
