Thread: Upgrade Terminator EFI to have transmission control?

    Default Upgrade Terminator EFI to have transmission control?

    I have a V4 Terminator EFI kit on my 496 big block Chevy running great. After blowing up a few 700R4 transmissions, it's time to upgrade to a 4L80E. So what I'm asking, can I plug an upgraded ECU with transmission control into my current throttle body/wire harness and just add the transmission side harness? If this is possible, can you point me to the correct parts I need? Thanks.

    Yes, you'll need the Holley Dominator ECU & the J4 transmission harness.
