Looking for help, so I have a 1999 pcm from a Silverado 1500 4x4 with a lm7. I am wanting to change the transmission to a 4l80e as well as convert it to a 4x2. Can anyone lead me in the direction to do so? I have looked extensively everywhere to find an xdf or even what to update the os to however cannot find anything. My os is 9365637, all responses and help is appreciated very much, thanks!
*EDIT* My hardware type is as follows 16220610. If that helps any, I am really trying to figure this out.

It looks like the 2002 Silverado had an LM7, on OSID 1221215 which has well defined XDFs. I'd probably back up the current PCM, swap to that OS, and then try and modify the 2002 bin for the car.
