Gearbox design
(OP)
Anyone know of a good source on automotive gearbox design? I know I can use classical strengths, gear and bearing design equations to design everything around. However, I would like to glean any usefull info I can to make the design flow much easier. So, any ideas?

Exactly, that is why I'm hoping for some good material to read. I'm actually looking at retrofitting a transmission with dog faced gears for road racing.

Nevertheless, the question remains: Any text available?

I thought you said it already had the dog faced gears and were converting to the spline, when I first read this.
I have seen the face dog type and think it is much easier for that design to wear and create axial thrust and slip out of gear easy. If that was a great design then outfits like Dana /Roadranger would be using it in heavy duty truck transmissions. What is needed is a good study of some good existing manual transmissions for some ideas.

ISBN: 0212853336.
It's a book from around 1970 but the writer has alot of experience with Formula 1 and other high performance automotive gearboxes.
It is old but has alot of truths and principles still apropriate today.

You did not really specify what this gearbox will be used for. The end use requirements will make a huge difference in how you design and analyze the gearbox, and also in what reference material you use in your work.
If it's a racing gearbox with limited life requirements, low weight requirements, no need for high production rates and little concern with cost, then you will design the gearbox in one manner. I don't know of any good texts covering race gearbox design. Your best bet would be to get friendly with someone that works at a company like Xtrac, Weissman, Hewland or Quaife, and pick their brains.
If it's an on-road gearbox, needing quiet operation, smooth shifting, long life, high reliability and low cost, then you would design the gearbox another way. The hardest gearbox to design, by far, is the production automotive gearbox. Designing gears, bearings, shafts and synchro rings that are durable, low cost, easy to assemble and totally reliable is incredibly difficult. The best resource for production automotive gearbox texts is the SAE. But they're not cheap.
Good luck.
