so i took my blown transmission out and put a rebuilt transmission in today.. i put a spec 2 clutch in which i love. But.... Every gear shifts butttter smooth, but in third and 5th gear, mostly 5th it sounds like theres like air passing through noise.. u can only hear it with the windows shut and radio off.. only on the gas. Any ideas what it could be? or u think im just crazy and to ignore it.
