I'm also under the belief that proper break in (run in) is essential. The break in period is just as important (if not more) to the gearbox as engine internals. Our cars have a 2 stage break in period. I'd speculate that most don't perfectly follow the first stage break in (1200 miles), and extremely few follow the second stage to the letter as it's over 2X the mileage of the first stage. I'm in stage 2 and following it to the letter. Overreving and too much load can't be good for the gearbox during this period. I'll finish the second stage and see if I ever have issues. Then again, I'm typically kind to my vehicles.
