Resetting the TCM and flash-updating it are two different things.

Don't. Let the dealer do that if they need to when you have them
flash-update it.

Yes.

No the torque converter is not sealed. Fluid is pumped into and
out of it. If it was sealed the fluid inside it would overheat.

No. Don't do that.

You probably have Dexron+Lubeguard not ATF+3 in there.

Yes.

Look again at how much space they had to work with. The
FWD layout is not optimal. The trans is crammed into the
engine compartment. I'm all for newer materials and such
but there' s no substitute for meaty, beefy, thick components.
And there is no space for that in a FWD. So, they try to
get around the lack of space by making everything thinner
out of fancy materials. Sometimes it works, other times
it don't.
