2016 mustang 3 relay tansbrake

So im working on a 2016 ecoboost mustang, tied to use a 3 relay transbrake, that exhanges SSB and SSC signals and cuts lpc to raise line pressure, the result wasnt good, the transmission goes into some sort of limp mode after i activate the transbrake once and it does not go away until i turn the car on and back on again.

it started throwing codes, first it was lpc circuit open, i set it to "no error reported", then shift solenoid B and i set it to "no error reported", then shift solenoid C andd also set it to "no error reported, after that it would not show the wrench light but still got into the limp mode.

what changes do you guys do to make it work on your cars?
