1SH, did the 12212156 file work out (does your 'Hoe run...?)...?
It did! I drove it home today. I even did a little brake stalling and tire burning to ensure proper operation :D
EDIT: Actually I had to find the same OS. The 12212156 OS didnt work.
Cool... good job. :cheers:

What steps did you do...?
(edit: note to self: he started with 4L60E 12216125).
I took the tune from a 8.1L/4L80E, same OS as mine. 12216125
I opened it and my dyno tune, then just followed the steps in the segment copy directions. I copied the trans calibration and trans diagnostic segments into my dyno tune and loaded it in the PCM. I started up and ran great first try. It works wonders when you can find the same OS to copy from.
Thanks for helping me out:cheers:
what if you have OS 09381344?
this is the only missing link in my 4L80e conversion...
thanks!
For your truck, I'd suggest bumping up to an 01 or 02 OS before doing a segment swap. 12212156 for example. Could then run a COS as well.Quote:
