Query of the 4L60E transmission to determine its vintage via cmputer?

Perhaps a silly question but:
Is there a way to log into the transmission via a computer
link and what VIN Number and Transmission version the Transmission computer
thinks it is ??

I had heard that if I swap a new replacement transmission into my car
even though the transmission is the same model year, the computer talks to the main car
computer and validates VIN numbers against each other. If the parts are from
different cars the transmission will not work.

I think some of these cars now have multiple computers.

1.) Engine computer ( ECM ?)
2.) Tranmission computer ( PCM?)
3.) Body computer ( don't know the jargon ) does the ABS, CAN bus and blue tooth stuff.
4.) Air Bag Computer - releases the airbags and fails into an OPEN state so you
cannot re-use it and also the car will not start.

So I figure it does not hurt to prepare in advance before I
swap a big part into my car.

These cars don't do that. You can learn all you need to know about 94/5/6 transmission interchange from this thread here:

As long as the wiring harness is compatible with the year and tune in the PCM, you'll be fine. No separate transmission computers on these cars.

Get yourself a set of factory service manuals for your cars; invaluable info.

Also, the N in VIN stands for NUMBER, there is no need to put the word number after VIN. Same with ATM and PIN.
