Synchronized transmissions make double clutching obsolete, split transmissions
are very useful in heavy (equipment) haul applications and here you
get a special
endorsement if all you use for your test on a big truck is an automatic.
Personally I would rather ask the person to back up the semi (and trailers) and
if they can't - - - no job who cares what transmission they use! But
not being able
to shift a transmission is a huge deal - - - I have had the joy of
dropping a shift
on a long hill when it was icy - - - that was NOT a fun experience!!!!
