Tater - Not necessarily. It wasn't until the advent of the current diesels that the auto manufacturers started to get serious about tranny design. For years, we had simple three speed trannies. Now look at them: 5 and 6 speed are the norm. But, you also have to bear in mind one simple fact: in order to increase the power available at the drive axle for a given speed, you must increase the HP output of the engine even if that involves a decrease in the torque output of the engine.
firebird - While it is true that HP will control the speed at which you can pull a load, torque does not indicate how much of a load you can pull. Gearing does. Just look at the mules at the airport. They have small (usually gas, but that is changing) engines but the regularly pull aircraft weighing in the 100's of thousands of pounds. They don't go very fast, but they do go.
