I hopped into my car one day(00 lude 5 spd) and i had no pressure on the clutch. I opened my reservior and its empty...poured some manual tranny fluid in and took it for spin....pressure slowly came back but doesnt seem like its fully back after a 30 min drive.....wat ya guys think tha prob is???? should i bleed the clutch lines for air???? if so how would i do that??? thanks alot
