I don't know about other cars, but for kelisa, auto transmission
only have 4 gear. Manual have 5 gear. More gear (with correctly
calculated gear ratio) should be more efficient in builting speed.
Also the last gear's ratio can afford to be bigger, compared to
lesser gear. Thus at say 100kph, manual's rpm would be around 2800
at the fifth gear, while auto would be over over 3000. And thus the
FC is always better for manual cars compared to auto.
Secondly, the more complex the system is (manual, tritonic......)
the heavier the car, the more expensive the car, the more
maintainene needed.
Of course there is this occasional Jams to consider about, but it
isn't that bad. Worst I encounter is stuck 1 hour travelling about
1km road.
