Bryan, I don't know what your problem was, but I disagree. I've done full
throttle in first gear all the way out to redline, even with a warmed-over
motor, and NEVER broken a layshaft gear. I have worn out a few layshafts,
certainly it's maximum stress and wear, but never broken a tooth.
And BTW, straight-cut gears are STRONGER than helical cut ... that's why big
truck transmissions whine so loudly (and typically don't have synchromesh), they
use straight-cut gears for strength.
