    4l60e to a 4l80 w ckperformance D3 valve body

    Has anyone here done the swap with the ck performance D3 valve body? what am i missing? the issues I am having is the scanner is showing in the D1 position but the current gear shows 2nd. and my speedo is only reading half the mph that i am really doing, so I am wondering if i am missing a setting for the second speed sensor. I did do all the wiring conversions at the trans plug as well as the ecm.

    What size of tires are you running? Your tune says your gear ratio is 3.73.

    Ok so now i have done segment swap is there anything i need to change in the settings, to make it work with the Ckperformance D3 valve body? I only ask since with the D3 you have to disconnect the EPC wire from the ecm , cause with this valve body that wire is now the trans brake activation wire and the trans pressure is set at 220psi in all gears.

    Not sure about that valve body,I'd run it and see if it pops a code.
