Will I get the firm shifts also?
Is there an upgrade program for my 7194?

I have the same issue. I came from the 9t08 crom and tried to upgrade to 9r20. Now Im trying to flash and it wont let me.
Wont detect on Downloader....

Help!! Was this ever resolved?

Would any of the above crom be compatible with my 09 yukon xl 5.3L?
