Operating System

[chuck1960]

Hello to everyone, I've been reading and searching and more reading before asking for help but still unsure about finding a matching OS for the 4L60E to 4L80E segment swap. I purchased hp pro about a month ago and have been looking at some tunes in the repository but unsure as to what I need. I have a 67 C10 with a 2007 6.0 with a t76 turbo that has killed a 4l60 and 4l65. I have had the swap completed for about 6 months and was going to try the relay swap but decided on the segment instead. If anyone could steer me in the right direction I would really appreciate it. My current OS is a 1250069, but since it's a custom 2 bar sd tune and it says it has been converted from a different number, does that matter. I'm trying to get this finished before our fall rod run in pigeon forge tn.
Again thanks

I have OS 12613248 but have had no luck matching it for the 4l80E. My I've been looking in the 2006, 2007 models but have either overlooked or just not seen a matching file. If someone could steer me in the direction needed I don't mind trying, this is new to me.
