Engine seized? 118k miles

Is it not possible to remove the trans by doing the following?

1, Disconnect inverter from transaxle.

2. Remove passenger axle.

3. Hook lifting assembly to trans

4. Undo trans mounts and driver axle.

5. Shift trans toward passenger side and lift out of the top,

I know this probably doesn’t encompass all that is needed to get the trans out, but it’s got the major things that should be holding it in.

 

With all of the listings on eBay for a Gen 3 flywheel, I’d reach out to one of the sellers and ask if they have the damper available.

 

Can you install the trans on the engine, then install them together?
Or is there not enough room?

 

Did you find the proper part number, for the damper? Is it considered part of the engine or transaxle?

Some info attached on removal/install, don't see anything on rebuild, as yet:

 

@Jamesmlemay does the engine turn over easily, say if you've got the spark plugs out and have a socket, extension and ratchet on the crankshaft? Apologies if this is old ground; I'm just wondering how and why that damper seized. Hopefully the damper failure is not the end result of further engine problems.
