when i shift in to 2nd at high rpms like 5500 and up it grinds and when i shift at low rpms it's fine please help me with this

Yeah I got the exact same problem. I figure its worn syncros or somethin. Just a guess though. I'm fixin up my tranny soon. Hopefully the KDS performance NVT350 rebuild kit will have whatever is causing this.

She's a good car. But it's time for me to move on. I'll miss her more than anything but my next car will have the same heart with the same passionate drivers. I hope things workout best for the both of us.
