    6.0l w/ factory iron heads will not bolt up to a LS1 style 4l60e. I assume that is the question you're asking.

    That's strange,my iron headed 6.0 bolted up to my 98 4L60E with a simple slotting of the flexplate holes,AFAIK should be the same for a 95,not sure about the electronicsthough.However,it will NOT work with a 1999+ LS style 4L60E...

    You are correct, you'd have to use the older style LT1 compatible transmission. Edited post for clarity.

    thanks guys. i belive the electronics wont be a problem. THe 4l60e is not a ls style trans. ITs is the early syle one that came in the truck. I will get another trans and mock it up before the
    lq4 goin in the truck.

    The new computer will not be able to control the old trans...

    why wouldn't my old 4l60e work. IT has the 13 pin trans connector. I work at a dealership. We have a tech that did this same swap in his 95 k1500. He used a newer 6.0 but he had no problem with the electronics. shift and drives great.

    im not getting a new transmission. My 4l60e is built to handle a lot more power. I am not using this truck for a race truck. this will be a daily driver. basicaly leaving the motor stock.

    Correct me if I'm wrong, but none of the 95 trans's came with a 13 pin, so if alterations were made, then that would change the landscape a bit.
