I am new to the forum so forgive me if there is already a discussion on this. I recently purchased a 2003 Z4 3.0i with a 6 speed manual transmission. The problem I'm having is that there seems to be a little bit of "grinding" and sticking between some of the gears. It's most pronounced between 1st and 2nd but noticeable between the others as well. The clutch pedal feels fine and seems to engage at the right place and I haven't noticed any of the usual symptoms of a bad clutch. Could the grinding and sticking be a sign of a clutch that is going out or is there something else to look into such as linkage, fluid, etc.? I appreciate any comment or advice.
