Anyone have a T42 program for a 4L80E?
I didn't see one on the drop box location, referenced.
TIA,

What year specifically? There's a 2007 Van tune there. I have a 2009 G3500 Van tune I posted in my 4L80E thread ... also the 2007 tune was uploaded un same first post

I'm looking for T42 for 2011 6.0L Silverado 2500, but I'm kind of worried thinking that all that was out there then was the 6 speed automatics. I'm trying to figure out if I can use my dad's 4L80E with the ecu or if I have to switch the tune and possibly eliminate the Cylinder Deactivation by changing out the cam and components before I put the motor in his truck. It has the E78 ECU with it
One of my buddies has access to a 2011 4x4 dually at his work ... will just need to pull tune if I drop by there one of these days.

They never made any 2007.5+ 2500/3500 pickup truck with a 4L80. It is/was either 6L90 (gas) or Allison 1000 (diesel).

many thanks to Ross and Paul
