You can't shift gears on an automatic transmission because, as it is called, it's automatic! You don't need to shift, it does it for you. == == Maybe the question should be "Why is my automatic transmission not shifting through gears for me as it should?" Could it be a fairly simlpe fix or am I losing my transmission? Yeah Dopey!

The transmissions aren't made by Freightliner, and this answer applies to all commercial truck manufacturers. A fully automatic transmission is clutch free. An autoshift basically adds a synchroniser gear and computer operated shift mechanism to a manual transmission, and still uses a clutch. With an autoshift, poor clutch manipulation often causes the synchroniser gear to go out, making the transmission unable to shift. On a fully automatic transmission, that problem does not exist.

What are the main differences when driving a manual transmission car compared to driving a car with an automatic transmission?
The engine has the same power no matter the transmission. However with an automatic transmission more of the available power is lost due to the torque converter and the transfer of fluid to torque. But in modern cars today it is very little, so get an automatic if that is what you want. A manual transmission does provide more power to the drive wheels but it comes at a penalty. You must shift it yourself.
A manual transmission will require a driver operated clutch pedal to shift gears, and thus allow for shifting on demand as opposed to waiting for a computer to determine shift points. An automatic transmission uses computer algorithms to determine shift points based upon engine load, speed, and overall fuel economy. More driveline drag exists with an automatic transmission because of more moving parts, and thus an automatic will typically have slightly lower fuel economy than…
