There may not be a 12216125 4L80E file... you may have to run a 12212156 4L80E file instead.

Thanks i appreciate the reply, i searched all weekend and when i would try to open a different os number for comparison, my unit told me it was wrong and wouldnt open it, so i ordered a harness that will operate the 80 off of the 60 tune hopefully it works as it says it will thanks again

The 2002 Express van with an L31 5.7L engine had a 4L80E as an option. This should be in the database somewhere. If you can't find it, I can upload it.

Avalanche with the 8.1 had an 80E behind them, were DBW, and used this OS. You might need to bench flash a PCM, I havent found any tunes in EFILive format with this OS and 80E trans segment.

I know, I have xidlesia on those two calibration id's

12212156 vs 12216125

they look the same


and I sometimes type this

12212165

so now you can't tell which one I really meant
