    E46 5.3 LS swap with 4L60E auto transmission

    Hi guys,
    I am currently getting things together for a LS swap into a 2003 E46 coupe.
    The majority of people douing this swap use the T56 6 speed and there seems to bee a good bit of information about this swap. What I am looking for is more information and ideas on using the 4L60E auto transmission.

    Is there anyone out there that makes a kit for the swap using the auto trans? Specifically the headers, seems the CX Racing headers will not work due to the transmission pan on the auto.

    What parts of the CX racing kit will work? I assume engine mounts will, and I would like to use the Holley oil pan.

    Can anyone link me to others that have done the same swap (non turbo)?

    are you planning on modding it at all? would highly recommend the 4L80E over the 60...


    Can't help with the CX stuff in e46 though but i'm sure others can

    Well, it will probably be a long term project that will evolve over time. My engine is about 400HP at the crank so obviously I need to support that. I was going to get an upgraded 4L60E with the stronger sun shell and whatever the other standard upgrades are. My concern with the 4L80E is physical size, its already going to be a challenge using the bigger auto trans and I would like to keep tunnel modifications to a minimum.

    If I go crazy down the road (years from now) and go turbo I will have to pull the engine for upgrades, so I could upgrade to the 4L80E at that time.
