    has anyone else successfully done this? My 4l60e is on its way out, and instead of throwing in another ****ty "4" speed I think having the 6 speed will be wonderful especially with the i5 motor, having more gears to go through would be a big difference! So far, if i understand correctly, i will need to buy that adapter plate for the trans to mate with the i5, a 6l80e trans, a new spline shaft, and the TBMS harness/computer. then just bolt everything in.

    If your vehicle has a TCM, then yes this is all is needed plus a torque converter.
    Offcourse the trans needs to come from an AWD 2007/2008/2009 and maybe up to 2011 since the valve body of the 6l80e was revised sometime during that period.

    08 up has an E67 pcm and T42 Tcm. The kit made by tbms adapts the T43 of the 6l80e to the T42.

    I have an output shaft that will be here any day now and will be sending that off to get resplined. Once I have it swapped, I will have a core output shaft to send to the next swapper to get resplined.

    The 6l80e wasn't adapted to an I5.

    They actually make an adapter plate that allows you to bolt it up!

    Really? Wouldn't the 6l80 need its input shaft replaced to also bolt up (if the 4l60 needs work to convert from an I5 specific 4l60 to a V8 specific 4l60 i would assume the 6l80 will need work to adapt from a V8 to an I5, besides the custom bellhousing (unless there is a oem bellhousing for the 6l80 on the I5).

    You will need a TCM and somehow modify the harness to incorporate the input speed sensor on the trans (06 models have an output speed sensor only at the transfer case).

    I believe you are correct the input shaft would need to be swapped, and if you go to page one of this thread you can see that adventr posted a link to tbms website with the adapter plate for the i5.

    I took a look at that link and yes they have an adapter plate but thats for the transfer case to bolt up in the correct location to the the transmission.
    Also, the input shaft they mention is the transfer case input shaft.
    They don't mention the transmission input shaft nor bellhousing.
    Since all H3s have the same transfer case body, this adapter will work on all H3s.
    But bolting the trans itself to the back of the engine requires a trans/engine specific bellhousing. For a 6l80 this is available for all LS platforms.
    What im asking, is there a bellhousing to bolt the trans to the back of the I5?

    Did some research

    http://gmtnation.com/forums/threads/...ter-kit.13828/


    This adapter will somehow allow to bolt the 6l80 behind the atlas engine (3.5/3.7) but will require modifying.

    Below is a link for the manufacturer:

    http://www.emtechmotorsports.com/block_adapter.html

    But, tbms only makes the harness to adapt the 6l80 to 2008+ H3 models (they use an E67+T42) and not the 2006/2007 model
