How does my car know the difference between first and fith gear as i go up through them the car speeds up?
Answers:
More modern cars have a speed sensor that tells the computer what's going on, and the computer controls shifting.
On older cars, the transmission valve body controls shifting by sensing various hydraulic pressures created as the car speeds up, and vacuum input from the engine.
thats just the way cars r built.. its quite simple in mechanism.. its like a bike with gears.. when u start pedaling in the lower gear in a bike, u need to pedal a lot to get to speed but as u start going to higher gears u need to pedal lesser n the speed is more.. simple mechanics.. Also when u start off from a stop on a higher gear its really hard to get speed quickly.. also its really hard to go uphill on a higher gear on a bike so its the same thing with a car..
Paul is right on this one. my husband builds transmission's for a living.
hydrolics, gear ratio. torque converter.
I suggest going to auto.howstuffworks.com and looking at the article on transmissions. It'll explain how low gear combinations convert engine speed to torque, or power, for starting and hills; and how higher gears create less torque but more speed for highway driving.
You didn't say if your question was about automatic or manual transmissions, but the HowStuffWorks site explains both.
