I'm putting a 4L80E in my 2000 Silverado Z71 4x4 with the NP241 transfer case in place of the 4L60E. This is an Autotrac truck. Has anyone got a 4L80E file they can send me that will work in this truck?

The trans is being shipped to me next week along with a rebuilt transfer case modified to accept the 4L80E output shaft. It'll take me a week or three to get it installed as I'll only be working in the evenings, so I have at least that long to get the new segment loaded into my program.

I've also had a custom crossmember made up, and the shop that made it is planning to sell them once we verify that it works in mine. I can post up pics and a link to the shop once it's finalized for anyone interested. This is not a modified stock crossmember like what PATC sells, it's (at this time) a one-off piece formed of square tubing. I won't post pics until it's been installed though, in case there are any bugs to work out.

Thanks in advance, guys.
