    Default 4l80e Swap with COS5

    I have a turbo F-Body that has already been converted to OS 2020005 and I am looking to swap my 4l60e to a 4l80e. Can I still just do a segment swap from a truck with OS 12212156 since that is was 2020005 is supposed to be based on or do I need to go about it some other way? Also, if I can just segment swap it, does anyone know where I can get one for 12212156?

    Thanks

    I can send you a 0202005 COS5 with a 4l80 already segment swapped.

    Will a 5.3/4L80E work or do you need a 5.7 or 6.0 engine segment?

    It's a 5.7 but it shouldn't matter if I'm gonna have to copy over all the tables from my engine tune right? Actually, shouldn't I be able to export the trans segment and swap it with my current tune?

    This one also has the Min TPS TCC disabled So when you let off throttle it wont unlock converter like a stock 4l80 tune.

    To answer your original question, you can do the 4L80E trans segments (2 segments, the trans segment and the trans dtc/error segment) on top of your COS5.

    But be sure to check/compare your tables before/after.
