[TR] use of overdrive

[Gary Nafziger]

I've never had an overdrive such as the A-type in a car before (tr-6).  I love 
it but am curious about it's use.  It works very well within a gear range.  But 
is there a way to quickly shift from 2nd overdrive into 3rd regular 
(underdrive)?  Then on through the gears giving a person 7 gears? LOL  or 
not.......i've been afraid to experiment and don't really need it but just 
curious.
