    4l80e segment swap completed, second set of eyes please

    I've completed a 4l80e swap into my 02 Yukon that had a 4l60e. I'm having issues with the trans being stuck in limp mode, 2nd gear and reverse only.

    I'd like to rule out my tune.

    Can someone take a look at my tune to see if I actually properly setup a 4l80e segment swap.

    I've attached:

    - Stock 02 Yukon ROM
    - Source 4l80e Avalanche ROM
    - The ROM I pulled from my Yukon PCM that should have the segment swap and other parts needed to command the 4l80e. Its named "Read_2_blah_blah....hpt"

    I'd really appreciate any input!

    -Eric

    Sorry to beg!

    If someone could verify I actually performed the segment swap correctly, I'd really appreciate it!

    Do you see the right meta data, tables and values?
