I'm helping a family member diagnose this problem. The clutch pedal on his 2008 G37s has lost pressure. The clutch will not engage.
He cannot afford much right now and certainly cannot afford to replace the clutch. Is there a possibility this issue is something other than a bad clutch like an air bubble in the hydraulic system, bad fluid or a bad master/slave cylinder?
He was told by a local garage that in order to diagnose the problem, the trans has to be dropped @$1000. I've never heard of a trans having to be dropped in order to diagnose a clutch problem. Is this true? He is being told $3500 for the clutch replacement. This too sounds incorrect to me - at least $2000 over what I would think it should be.
I'm hoping you guys can help verify what this mechanic is telling him and lend some feedback as to what this issue might be.
