    4T65e FWD ---> 4L60e (RWD) on a 2000 Pontiac GTP. 3800 L67 (SC)
    -I edited for clarification, on the Pontiac GTP
    edit: Yes i have a STROKE, be nice to me.....My words don't always mean what i want them to..
    Yup in new-ish to this, ive done OBD1 alot (burners, chips etc.) but new to this OBD2 stuff
    *I have bought HPtuners
    and i have some other bin stuff, guides etc.
    This is for my jeep, 4L60e transmission, yes i know, its matted up....
    So...
    This is not as easy as liked, i 'thought' they would be a 'segment swap' and id be done.....
    with a little bit of mucking around.
    nope....
    so.... what the best way? and the hard way to do this ?

    I would probably run a stand alone 4L60e control box and then have the bonneville computer run the 3800.

    You can't use the segment swap on the 3800 computers.

    Or you could maybe get fancy and see if you could use a holden computer because those are RWD from the factory. But then you'd need the wiring harness from that car too and I'm not sure if they used the exact same transmission.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    Look like i going go with a 'top swap' with a camaro/firebird.
    They also came w/the 3800, but with out the Supercharger.
    I appears that they have all the same tables for a SC, just not filled out or as much.
    There is a flag that basically 'turns on' the SC
    I know that they have more/less the same intake/injectors just dialed down.
    Then its just cutting/pasting in my motor.... back in, over top of the camaro...
    ..
    Anyone had to do this ? Sounds right ?
