T56 pcm reflashed for a 4l60?

I am picking up a built 4l60 from a buddy for an auto conversion.... Can I have my t56 pcm flashed to run the 4l60 and use a wiring harness out of an automatic car?

Yes, shouldn't be an issue with HP tuners.

Should work. I went 4L60 to T56, that's what my tuner did. Worked fine.

Yes, with EFILive I believe you need to do a full OS reflash (even though the OS doesn't change) with an A4 tune.
