I was talking to a friend and kinda said maybe I'll swap out the flywheel in my accord.
He told me that only manual trannys have flywheels.
Is this true?

 

no a flywheel is used in both auto and manual cars it serves 2 purpose

1. allows you to start car
2. helps smooth out engine vibration

 

Well, there has to be a way to connect the trans to the engine for power transfer. Most people think of a flywheel as that huge hunk of metal bolted on when you have a manual transmission for the clutch. The auto transmission uses a very thin flywheel or more commonly called a flexplate. Not something you can usually replace or lighten for any gain on an auto transmission.

 

They Both Have Flywheels Sometimes there called flexplates, either way If you replace the flywheel in an automatic you wont gain any performance, it dosnt add horsepower or anything either, even if u replaced it in a manual transmission,

its hard to describe the feeling of a lightend flywheel

 

Flywheels are for <U>Manual</U> transmissions - upgradeable = yes

Flexplates are for <U>Automatics</U> - upgradeable = probably not in the Honda world..

Aftermarket flexplates are used in the small block chevy world and other domestics...just not in hondas.

 

gotcha, thanks fellas.

 

The torque converter itself stores the majority of the momentum. There's no sense lightening the flexplate when it's a small fraction of the total.

 

autos have flexplates which are similar to flywheels, just thinner and not as robust since they dont need to make heavy contact with a clutch.

the flex plate is necessary to start the car, to turn the motor over.

the gear in the starter engages the outsize geared ring on both flywheels and flexplates to spin them to start the car.

its like prop plaes before electric starters. a guy would have to manually spin the blades.

also in old cars there was a hand crank that you had to spin by yourself pretty fast to start the car. same thing.

actually hand crank start you don't have to spin it fast, they make the rotational mess weighted so once you get the momentum going it will spins itself to start.
so it's more like alot of inital torque, not alot of "fast" or hp

henry ford first employed power starter on his mass produce ford after a friend of his broke his jaw bone cranking his car.

and skipping the boring history lecture, yes the auto does have a similar large diameter gear like thing called flex plate but it's not built as strong nor weighted since it doesn't have to be engage/disengage like a manual and it has little to do with the energy transfer(like jim said, that's the job of the double fan aka tq convertor)

 

go mushroom slap your freind in the face for saying auto's dont have flywheels.....

(mushroom slap = hitting your freind or who ever in the face with your dick to make a red mark that looks like a long mushroom. Used in homosexuality but not always... have fun and enjoy try to do it when he is drunk)
