I think people are getting ahead of themselves skipping the break in period and I don't mean the engine, how about the tranny, how about some heat cycles? wearing those gears in so they seat correcty? synchros, bearing, bushings, spacers, shime, springs etc... you think these parts don't need some wearing in?
I run my car hard, went easy on the shifting but hard on the engine for the first 500 miles, then got hard on the shifting when I felt comfortable, I have over 45 1/4 passes not a single issue.

I'm all for running the ENGINE hard on break in to get a good seat on the rings, but the tranny is a different beast, and all those parts inside have to get comfortable and run through some heat cycles they stretch, expand, contract etc...

30 passes right away powershifting and your garunteed for this to happen.
hell if you drive on the freeway too long when the car is BRAND new your will get a decent gear whine from the diff.
