    Hello Donald,

    The 4L80 came as original equipment in some GM vehicles in 2009 - but these used an E38 ECM. Your 2009 Colorado uses an E67 ECM.

    A Gen IV engine and a 4L80 is not a problem in a swap / or Hot Rod configuration, but may come with significant issues in your truck.

    Follow the link below and enter your VIN number.

    http://tis2web.service.gm.com

    Need to know the part numbers of the ECM OS, System, and Slave used in your truck. Also need to know all of the part numbers used by your current TCM.

    Will try and determine any possible OEM calibration compatibility with your truck and a 4L80 after you post this information.


    Regards,

    Yes - that is the ECM information. Now need the TCM information - OS and cal will probably begin with 242 .....

    OK … as always with these types of questions, there may not be a definitive answer - you may end up with a trial and error scenario.

    As a disclaimer, my so called area of expertise is Gen III conversions. Just getting up to speed on Gen IV applications - but am not offering these commercially yet. The focus of my R&D efforts has been with E38 ECMs - and I know very little about E67 applications. There maybe another Forum member who could offer an absolute “Yes” or “No” answer.

    The software in your E67 ECM is dissimilar to the E38 - including the Slave OS. On the positive side, the transmission OS and calibration in your TCM (T42) is very similar to TCMs that were paired with E38 ECMs.

    Your TCM uses OS 24243356 - which is the same TCM OS used by 2009 GM vehicles originally equipped with the 4L80. Therefore, you MAY be able to reflash your TCM to control a 4L80 while maintaining compatibility with your ECM and all of its functionality.

    If not, then you may be faced with running a stand alone TCM controller.

    The thread below is from a Forum member who began with a 6.2 L and 6L80, then changed to a 4L65 transmission. If memory serves, he ended up running a stand alone type setup. Obviously this thread is not directly applicable to your proposed swap, but should give you an idea of some of the potential obstacles.

    Good luck …
