What does the user have to do? Does the user HAVE to tell the car when to change gears? When stopping does the user have to maually put the car into 1st? Basically i want to know everything there is to know about semi automatic transmissions.Does anyone fully understand what and how a semi-automatic transmission works and what the user has to do?
simple, semi automatic means it will be automatic unless you decide you want to shift gears, you have the option of shifting them yourself without the clutch, and you also have the option for it to shift itself thats what semi-automatic means its kinda automatic not fully automatic because you may shift them if you like, its just a automatic transmission that has a user intereface that permits you shift them, here is a link to everything to know about automatic transmissions http://auto.howstuffworks.com/automatic- basically a automatic transmission that permits you shift them if you wish toDoes anyone fully understand what and how a semi-automatic transmission works and what the user has to do?
What is a semi-automatic transmission?



I've only ever heard of automatic and manual transmissions and recently a few CVT's (continuously variable transmission).



The first ';automatic'; transmissions, if you can really call them that, didn't operate quite like the ones today. You had to shift gears either going up or going down(can't remember which way) and the automatic transmission would handle the other direction. If you see Hydromatic Transmission - that's that.
In a semi-automatic, you do have to switch the gears and when speeding up or slowing down. However, most SMGs, Sequential Manual Gearbox, have an automatic mode so you don't have to change the gears at all. The car will just be faster and quicker if you shift the gears manually. And of course there is no clutch involved, there is usually just paddle shifters or a lever on the center console.
if im not mistaken all you have to do is tell it when to shift their should be a shifter button on the steering wheel.
basically, all a semi automatic transmission is, is a manual transmission with no clutch. You still have to change gears manually, you just don't have to push in a clutch. The semi-automatic transmission does that automatically.
basically you have the choice of when to shift yourself. The catch is it may not always shift when you want it to because it is programmed to shift only when it is safe to do so depending on many conditions such as temp, spped, load and rpm's. so it is exactly what it is called semi automatic
