    Been driving manual transmissions since the 70's, toe/heeling for over 10 years, know the names of all the components, but have never seen them in action. This consolidated all that knowledge into a functioning concept for me in 11 minutes. Everyone who drives a manual transmission vehicle should watch this and understand.

    Very educational, simple, and illustrative! Thank you for this video! But there's something missing that I've always been wanting to understand, and so hopefully you'll cover it in a follow-up video as other's have requested: How do the synchromeshes work (maybe with a tie-in with rev-matching / double-clutching)? And maybe in another video: How do dual-clutch transmissions work? And maybe yet in another video: How do modern automatic transmissions shift gears smoothly without jolting the car between shifts? Hope that's not asking for too much. Thank you for your educationally addicting videos!

    So far best video about manual transmission. *EVER* And it looks exactly the same like the one i got pulled out of my MK3 Jetta. 3rd gear and reverse were severely damaged, reverse was actually missing tooth or two.

    Great information and well explained. However best part was @ 10 minutes when each of you embraced your respective childhoods. The engineer with the engine noises and the mechanic switching gears was great.
