I had post before a problem i had with the first gear not engaging while on standstill. That happened something like three times and never got that problem again. I now have a smaller problem with the 1st to second gear that is steadily rough to shift. I also feel vibration through the gear stick. It usually is normal but for me is abit more intense that i've used to and gets faster with speed.This is more like background info for you guys to give me an opinion to my recent .."finding"

I gave the car to my friend to drive it and sat on the passengers seat. I'm 6' 3" and i can rest my legs on the very bottom of the footwell ,near the curb.
While he was driving in 1st or 2nd and on low speed , i could feel something between a vibration and knocking from the footwell. That was on the right hand side next to the main console (must be the other way to lhd cars), It was not stable vibration/knocking, had no pattern and intermmitent.

It seemed to me to be comming from the transmission. Has anybody else experienced this ? What do you think it might be ?
