ANY SUGGESTIONS; 99 Mitsubushi Eclipse 2.0 Spyder GST. I had the complete clutch replaced with an SACHS clutch, PP, Throw out bearing and a new ACT flywheel. After 2000 miles it went on me so we replaced it again this time with a heavy duty SACHS clutch. After 1000 miles the clutch is beginning to slip again. I am the only driver and NEVER ride the clutch or misuse it. It slips in 4th and 5th when putting the pedal to the metal while passing on freeway between 4000 and 5000 rpms, 70 to 80mph (while passing rpms will shoot up to red line and I back up as soon as I feel it slipping).

What I did... after changing first clutch, I replaced valve cover gasket to eliminate possible oil leaking on system. Now I and my mechanic are totally perplexed as what the problem can be.now mechanic wants to give up on all parts and use mitsubushi clutch and throw out bearing and pp... your thoughts?????? thanks ED
