Sure, there are some cars that offer a manual override - Volvo for one.
They are there for entertainment more than anything else.

Modern electronic automatic transmissions are pretty smart and are
programmed for economy, although some reprogram themselves to learn a
drivers habits to an extent. Don't expect that you will be able to
improve much on the economy of computer controlled engine mated to an
modern automatic though. The biggest impact you can have on fuel
economy is to take it easy on starts, keep the speed as constant as
possible, keep the tires inflated to the highest recommended pressure
and don't drive much faster than 55mph on the open highway.
