My 7 recently started idling odly between 800-1500 rpms, sometimes if stick at 15 other times is wavers between 800-1000 rpm... also when it idles I hear a rattling sound some of the time, It almost sounds like the belts but they are all new... any ideas?

Also shifting into first switfly results in me grinding gears, All other gears I can slam in when racing but first seems to be real sensitive, and Instead of in the selector column going from nuetral straight up to first, I have to go diagonally from below 3rd gear to first

same with second I have to swing around this barrier something in the tranny is causing





thanks for the feedback
