    What Operating System For My L92/6L80?

    Little background. I have installed a L92/6L80 into a 1965 Buick Skylark. Here is the problem. The motor and ECM are out of a 2007 Escalade as I found out later. The 6L80 transmission is out of a 2010 vehicle with the code of OCAA on the sticker. Probably something like an Escalade, Tahoe, Silverado or something along that line. The operating system in the transmission is 24254909. I don't know the VIN# of the transmission.

    I need to get an E38 that can communicate with the transmission and work with my motor. I would love to have an ECM out of a 2010 L99 Camaro as that is basically what my motor is now with the modifications. TSP VVT-3 camshaft, LS3 intake, LS3 throttle body and a card style MAF. From what research I have done I think I need a E38 with a service number of 12633238 as that seems to have been used in a lot of 2010 vehicles and later ones as well.

    Open to suggestions.

    Update: Maybe E38 OS 12635863 would work. I think this version is available in a 2010 L99 Camaro. It also appears to work with TCM 24254909. Just need confirmation before making a purchase.
