slight vibration in 1st gear on auto trans

I searched a fair bit and could not really find anything that matches my problem. It does not happen all the time, but still a fair bit to the point that it annoys the **** outta me. I notice it most when accelerating at 2-3k rpm, it kinda feels like a rim is bent but that is def not the case. Also as soon as it changes into 2nd it stops and does not happen in any other gear. If anyone know what this could be please let me know.

Thanks

How does the trans fluid look? Does it only happen when accelerating and nothing else?

Hmmm did this problem just start? I can't remember but when you have a vibration when accelerating..i want to say it's the trans or motor mounts? Not 100% though

What wheels and tires do your have on your car? A wheel may be out of balance I've had this problem before. I've got falken tires on my car and i know when they start to wear out they get alot of vibration.
