thank you guys. i changed tx (and clutch) oil about 6 months ago but it was running fine before and after. used what is advised in the manual. as i said, it was doing fine so i dont think is the oil.
it just happened now that is cold but i drove it last winter with the old oil and this spring with the new and no problem. still, cold it is the only thing that i could suspect.
also last winter with cold the stabilizer bar made a crack noise when turning when began driving. replaced it and now with cold no noise.
still, if it does not get worse will wait until spring and see what else comes to mind. from the beginning, pedal went to the floor but no noise and changing gears was smooth so i didnt think about it.
what started this all was the sudden rough feeling of the lever. i was hopping it had some sort of mechanical adjustment, like the parking brake. and i drive it year round.
thanks again.
