Hey for all of you who don't know how fast you're going, and your mileage is still as it was a year ago, here's how to fix it. (well at least how mine was fixed.) First if you have the same symptoms as i did which was: speedo didn't move, odometer and tripometer didn't move but rpm was fine, then you can try to do is..

1) Look at your speedsensor located below your oil filter.(it looks like a motor with a plastic yellow gear at the end)
2) Take it out by removing the single screw.
3) There is a rubber cap on it that should flushed with the speed sensor body. If it isn't flush, then that is most likely the problem.
4) To push it in you should use a clamp or i heard it is possible to do by hammering it in. Be careful not to break it though.

When i squeezed the rubber cap back in, some transmission oil leaked out..

Hope this helps.
