Ok i got my engine (ZC DOHC) and I have a dx tranny hooked up to it. I have a centerforce stage 2 zc clutch hooked up its been used for around 2 months and it works but some times when iam driving i will hit the gas hard and the engine revs as if i hav eth clucth in then it will come back when i let go of the gas why is this?? could it be b/c it needs to be worked in more?? could it be b/c it dosn't work with the dx tranny?? But i also have a tranny that came with the engine the number on it is L3 1201744 does anyone no what kind of tranny this is or where i could find out what it is??
