Just had a new clutch put in two weeks ago, however after I have gotten into 1st gear--when release the clutch noticable grinding occurs (can feel it under my feet). It is even worse after getting into 1st gear going up a hill. Doesn't seem to want to make a smooth shift. I have even tried to shift as perfect as possible and it will usually still grind. Took it back to the shop and they bled the system again and said try it now. same results. I know it's hard to say but does this sound like a problem due to installation or what?
