What are the pros and cons of lightening the a/t's flywheel be?

I know taking some of the weight out would provide a quicked throtle response, but taking to much weight out would cause slow speed and idle roughness.

Any other info someone can add to this? What am I missing?

Cars with A/T do not have Flywheels, they have torque converters. Don't expect to find a aftermarket torque converter for the low power version you have. It not cost effective since Mazda will add a better A/T in the future.

Now since the A/T apparently dosen't have a flywheel, what does the starter spin to start the car then? The Torque converter? I don't think so.
Mazda calls it a drive plate part # 19-021. I applogise if I confused you by calling at a flywheel.

it has a flywheel.. it's just not the same kind of flywheel as in an MT.

I always called them the ring gear. They are very flimsy light pieces anyways. Just enough mass that the starter has something to grab onto.

Well there goes that idea. I knew it wasn't the same as a MT. just throwing the idea out there.

Thanks everyone..

To better clarify: A/T cars have "flexplates" that have the ring gear that RG mentioned along with the mounting points where the torque converter is bolted on them. The flexplate connects the E-shaft to the T/C and a second purpose of the flexplate is to accomodate any slight mounting misalignments or imperfections that may have occurred during assembly/mating of the engine and transmission. These imperfections are normal. The diameter of the ring gears in the A/T and M/T models are exactly the same. The flexplate is also light enough that it would be a waste to try and lighten it even further.

Excellent input Charles! thanks for the simple and specific facts about how my car's
engine and tranny connect. I have always wondered how my A/T was similar and different than the M/T. Save this Thread!
