i have a 302 with a c4 automatic trans. do i need a flywheel or a flexplate... which ever one mine came it is bad and i need to replace it?

 

I have always discribed aFlywheel something the ring gear and torque converter are attached to (automatic C4)
I have always discribed aFlexplate something the clutch is attached to (manual trans)

I might be wrong, but I always thought they were transmission specific

 

A flexplate is used with an automatic transmission.

A flywheel is used with a manual transmission.

didnt know that, i thought it was the other way around

 

66gtkfb is right!!! flex is for auto anf fly is for manual!!!

 

yup, flex = auto. and fly = manual

 

Go back and read the previous post to mine. If it make sense to you, I've got some land in Florida for sale about 50 miles west of Ft Lauderdale.

gator huntin' and airboatin' good fun

 

Here is a internet explanation...clear as mudd

Description: The flywheel for most automatic transmissions/transaxles is simply a stamped-steel disc with a ring gear located at the outer edge for engagement with the starter�s pinion gear. With this type of flywheel, the torque converter has no ring gear. Some cars use a more modest flywheel known as a flexplate, which is all that�s needed because the torque converter itself has a ring gear located on its outer edge.

Purpose: The flywheel, or flexplate, mounts to the engine's crankshaft and also serves as a mounting location for the torque converter. Consequently, the flywheel or flexplate transmits engine torque to the torque converter housing. The flywheel�s ring gear also serves as an engagement point for the pinion of the starter motor when cranking the engine. Because of the lightweight design of the flywheel or flexplate, it does not help to smooth out power pulses from the engine like the flywheel does on a car with a manual transmission. On cars with automatic transmissions, the torque converter provides this function.

 

i dunno where you got that info but a "flexplate" will more times than not have the starter ring gear on it (not the torque converter)


trust me dude, flexplate = automatic / flywheel = manual
