Automatics don't have flywheels. So the short answer is no.

not trying to sound smart, i am thankful you at least put some input in, but i can name plenty of cars/trucks that are auto that have flywheels. or are you saying the TC a/t doesn't have one? i don't have a lot of knowledge on it like I said

I know the tc does not have one. I have never heard of an auto car having a flywheel. They do have flex plates however. I can't really see you dropping a whole lot of weight off a flex plate as they don't weigh much as it is.

Yes there is a flywheel. Is there a replacement for the tC? I dont know.

http://auto.howstuffworks.com/torque-converter2.htm

The housing of the torque converter is bolted to the flywheel of the engine, so it turns at whatever speed the engine is running at. The fins that make up the pump of the torque converter are attached to the housing, so they also turn at the same speed as the engine. The cutaway below shows how everything is connected inside the torque converter.

AT has a flex plate... They are already generally very light...

rebuilding the torque converter can make for more precise faster shift as well as upgrading the valve body...

havent seen anything yet for the tC though...

and sorry for going offtopic/jacking your thread for a quick moment.. but since we're on an A/T topic.. is it safe driving in any of the other gears (L, 2, 3)? .. or will it mess up the tranny.

Its not the smartest thing to do driving and winding out L & 2...

Your tranny was just locked out of 4th thats all, worst case bad gas mileage, from cruising in higher RPMs.

the flywheel in an a/t is already extremely light. One in a m/t on the other hand is heavier because it engages more and works harder. That's why lightened flywheels really only apply to m/t
