Hi all, I've had my '03 Accord for about 5 years now. Has 115K miles on it. Great car no problems until recently. Ironically, Just after I paid it off I started feeling a vibration when accelerating from 25mph through 35mph. Its a 5 speed manual 4 Cyl VTEC. I had it running on jack stands yesterday and put it in gear. The vibration seem to be in the transmission. Is there a common problem with the Honda manuals that would be the cause of this? I've had the tires balanced and rotated and the alignment done. The same vibration persist. I'm not saying for sure it's the trany. What else could it be? When the car was on the jacks and in gear, I did not feel the vibration out by the wheels, but when I touched trans/diff case I felt it strongest.
