Switching to a 16197427 to run a 4L80e.

I can find 16197427s everywhere reasonable BUT no one can tell me anything about the van or truck they came out of.

They cannot tell me what transmission, engine of even if it was even running when hit.

My old friend who had a junk yard would often say when asked if a part was any good, “Well it was moving when it hit something.” He could then show you to car or truck it came out of. Sadly he passed 7 years ago and wife sold yard.

So looks like I will need to load the basic operating system for a 350V8, for a 4L80e.

My read is I can get any 7427 and just reprogram it, is that right??

Or do I need to get a 7427 from a truck that had a 4L80e??

So far I have no clear answers.
