Most people know that cars come with two basic transmission types: manuals and automatics. But there's also something in between that offers the best of both worlds -- the dual-clutch transmission. Check it out.
Traction control helps limit tire slip in acceleration on slippery surfaces. Many of today's vehicles employ electronic controls to limit power delivery for the driver, eliminating wheel slip and helping the driver accelerate under control.
In a regular transmission the gears are literal gears -- interlocking toothed wheels. Continuously variable transmissions, on the other hand, don't have interlocking gears. The most common type operates on a pulley system. Learn all about the smooth-operating ultra-efficient CVT.
Combine the ease of an automatic with the driver control of a manual and what you've got is a sequential manual transmission. A simple forward push advances the gear. Learn all about the sequential gearbox.
Manual transmissions use mostly helical gears, but reverse is a special situation that requires a different type of gear -- a spur gear. Learn why a spur gear makes a loud whirring noise when the car's in reverse.
I see many dump trucks with wheels on two rear axles on the ground and a third axle with elevated wheels that can be lowered. These seem to be used when the truck is full -- but why include what must be expensive hardware to raise and lower the wheels? Why not just keep them down at all times?
What does that funny "H" pattern on my car's gear shift have to do with my transmission? How does it make the car change gears? And when I mess up and hear that horrible grinding sound, what is actually grinding?
