    Default 4l80e upshifting when held in gear

    Hi all.
    We are currently tuning a car with a 4l80e installed and when doing power runs the box will automatically shift from 1-2 and 2-3 when the shifter is holding gear. Is there a way to stop this happening? We cannot get the rpm we want before shifting manually. The box will shift automatically before 6000rpm.

    Thanks in advance.

    OK, did you figure out how to keep the 4l80e from shifting on its own?
    I thought that wasn't possible due to the design of the hardware.
    I would love to keep my tranny in the gear the shifter tells it to...
