SAE's online operations produce some good videos of mechanical
operation of car parts. Here's a video on contemporary manual
transmissions (conventional) that they link to at DriveLineNews.com.
If detents, synchronizers, blocking rings and clutch cones are a
little vague in your mind and you want to see them in action, take a
look at this.

I've driven nothing but manual transmission cars since 1971, and I
didn't find that video at all helpful in understanding the inner
workings of a manual transmission. It also was odd that most of the
driving footage showed vehicle traffic in Great Britain or Australia,
although the narrator had an obvious American accent.

This multi-page site doesn't have the nifty video, but it helped me make
much more sense of the workings of the transmission.
