flywheel?....flexplate?
Maybe I'm showing my age, but I have a question about parts/terminology...
Back in my "younger days"...as I remember
with an auto tranny, we'd bolt the fly wheel to the crankshaft, then bolt the tranny to the block, then turn the torque converter until the tabs lined up with the flywheel...install bolts and nuts...tighten, install cover, shifter and lines and go... 
On a previous thread there was a reference to a flexplate on an auto tranny...am I confused, or is there a part missing in my description...or is this new world terminology...
(Thought the flexplate was only on a manual tranny)

Flexplate is largly an aftermarket term.
Most OEMs, like not Chrysler, call the round thing that bolts to the back of the crankshaft a flywheel whether it's for a manual or automatic. Such as Flywheel, automatic transmission. This consistency ensures that everyone in engineering is talking about the same thing.
So, for an automatic, either flywheel or flexplate is correct usage.

Not exactly are they one and the same. Part of the problem of what to call it is that Chryslers with automatics have the ring gear on the converter and not the flex plate as does GM and Ford.
