before replacing my clutch i could feel the clutch peddle squeak.. Gears were hard so i decided to replace my clutch with an Exedy OEM replacement kit. i also flushed tranny oil and replaced it with Nissan 75w-85 bought at the dealer. i felt the clutch slightly better but gears are still pretty hard. I was told by a mechanic it could be the clutch fluid since it is low and dirty or master slave cylinder.Does anyone know what im looking at with this problem??

 

I think your mechanic has pointed out the obvious. You should start from there.
