    OK, do you know of any plans to have the 6L included? Thanks.

I don't see Holley or anyone else taking on this challenge, since it can not be done with simple PWM solenoid control like a 4L transmission.

    The 8L transmissions should be slightly easier since there's not an internal TCM, but they are still clutch to clutch shifting, so shift timing & torque management are very important to their survival.

    If you want to use a 6L transmission, I suggest you contact PCS directly and order the TCM-2650. You will need to wire the TPS, RPM & speed sensors into this module separately, since Holley doesn't make the CAN info available, and they talk at different CAN Bus speeds. -Greg
    Sounds good, but it's NOT simple. It isn't just a PWM solenoid. The new transmission PCM requires a torque signal from the PCM to the transmission to shift, and as of now GM & PCS are the only two that have it working.
