12216125 4l80 swap help

[jj5star]

I know this has been covered but i have looked for hours and can't find a stock 4l80e with this os 12216125.

does anyone know if one has been made?

Thanks,

I don't know if there is a 12216125 running the 4L80E...

but there is a 12212156, see post #29 here: Collecting-links-to-scattered-material-post-29 (https://forum.efilive.com/showthread.php?2990-Collecting-links-to-scattered-material&p=132156&viewfull=1#post132156)
