O.K. when I accelerate from dead stop...as soon as I hit about 3000 RPMS it seems/sounds like the engine is gonna blow. After that,(and shifting to second) the vehicle shifts fine, I can wind it out to about 5000 before it really tells me it wants to shift....is this normal???.......is my gear ratio messed up???..... I haven't done any mods that would effect the trans/clutch...what should i do?
