    04 gto m6 to 4l80e OS swap?

    Swapped the m6 for a 4l80. We are running a Fast EZ TCU. Do we need to swap the OS from a manual to auto??

    You won't need the OS change as long as you're running the standalone EZ-TCU.

    With that just need tach signal for RPM, TPS and VSS… 80e will shift with that info programmed into the Fast system
