this has been an issue for awhile and its half the reason why I parked the truck..long story short,old clutch went out so I had a family friend replace it..well,after he replaced it,it holds zero pressure,you could push the pedal down by blowing on it lol. He claims the throw-out bearing pushed through the flexplate?? I have no idea,transmissions arent my forte..all I know is it would be nice to have some pressure when I push the clutch in..it still engages/disengages just fine,i just hate the soft pedal...truck will be apart in a few weeks so if I have to ill post some pics
