Thank you Paul, and I'm looking forward to the the new article.

So, if I understand it a little more correctly now, the early version has "straighter" cut gears than the later version greater angle cut gears ...and both are categorized as helical cut design.
Seems like somewhere along the way people got used to just saying 'straight cut' when referring to the early version transmissions.

If increased trans whine wasn't present before clutch service, and also now has slightly noticeable whine while car is stationary, that would narrow it down to an alignment issue.
