i have a 99 mitsubishi eclipse rs with a manual trans. the trans was
rebuilt about half a year a go and runs fine. but the problem is that i
cant put it in any gear. it started yesterday on my way home from
school when i noticed that it was getting harder and harder to put it
in gear. then about half way home it just wouldnt allow me to switch
any gear. i had parked it on a side street  and drove it home by
starting it in gear and was able to switch to all gears without the
clutch as  i was driving.i got it to my garage and i started jacking up
the car on both sides into the air. then just for the heck of it i
figured id start it and see if it went into gears and it went into all
gears fairly easily with just a little bit of effort. but then i
noticed that when i stepped on the clutch the rpms would stay the same
along with the speed. i was even able to accelerate while holding the
clutch down. then as i stepped on the clutch and the brake the car
would stall out. i bled the clutch to see if that would do anything and
it didnt. im thinking it might be the throw out bearing or the clutch
itself but it is not slipping. i was even able to top out the car while
in the air at 150. if anybody has any ideas on what it might be it
would be greatly appreciated. thank you
