My B has overdrive and thankfully it is working fine. My question though may be simple but how does it actually work?  I appreciate it is an "electric" overdrive but that electrical component must somehow be transferred to a mechanical advantage. I pondered this while driving back fro Halifax yesterday...the places you your mind goes when driving in the sun with the top down!
