Thank you, David.
That video was "Time well spent." I'm VERY glad I watched this as I now feel I have a much better understanding of what an Allison Transmission looks like on the inside AND more importantly, how exactly its' gearing and computer work.
After this video was over I watched a couple other Allison videos and found them very informative also.
There is MUCH to learn ... like eating an elephant, I'll slowly bite-off a little at a time till I realize that it's ALL GOOD!
Thank YOU for suggesting (suggest away if you know/find any others).
