back on topic... yeah, I think my rotors may have a little warpage - not much, but a litte...
Does the shaking occur in every gear at 3k RPM's? or just certain gears? That could be relevant in determining if it's the tranny.
Also, I've had my tires balanced at places before whose machines were screwed up and actually messed up my balance. I wound up going to the stealership whose machine was right and they would actually guarantee their work - they were able to get it right... so you might want to check on that. The only way I can think of to test that is to switch your front and back tires (in a normal rotation pattern) and see if it still does it. If not, then it probably is just the tires... if it still does it there's a chance the tires are screwed up on both front and back or it might not be tire balance.
Hope this helps...
