will a manual transmission flywheel fit in a automatic transmission ?

is the manual tranny flywheel lighter then the automatic tranny flywheel?

 

Automatic transmissions don't use a flywheel period. They use a flexplate and a torque converter. No they do not interchange.

 

they dont use a flywheel i swear i jammed it to get off the crank pulley....

edit.
or is that just what the flex plate and torque converter look like?
wouldnt that mean i would need a flywheel to make it manual to?

 

yes you would need a flywheel to make it a manual transmission. it's what the pressure plate bolts to.

 

make sure you use flywheel bolts. the flex plate bolts are weaker.
