Weird issues with transmission and intermittent loss of communication with other modules

[xp3]

Hello everyone, been having a lot of issues with my car lately mainly with the transmission and ABS. Most of the time when I shift it into reverse or drive/low gear it wont move unless I give it some gas which wasn't the case before, it would move by itself with the brakes released. Sometimes it decides to work like it's supposed to for a few seconds and then it goes out. Also the gear, ABS and airbag light flashes randomly for a split second then goes out. I've been chasing these codes U0401:00-6C , U0401:00-2F and P0480:13-2F for a while now to no avail. The ABS recently went out but it also used to drive by itself without the ABS (I had intermittent no communication with the ABS). I read the live datastream last night and some things that caught my eyes are the clutch A and B are fully OPEN, the measured clutch slip for both A and B is the same speed as the engine (1000), radiator fans come on at 108 C, module supply voltage is 13.791 V and battery is like 14.2 V, input shaft speed for A and B is 0 RPM, "Self Calibration Prevented - Actuator Supply Voltage" - YES, "Self Calibration Prevented - Clutch A (and B) Is Not Open" - YES, Shift Fork A Actuator Position - Measured(A) - First Gear (it's the same with Target), Shift Fork B Actuator Position - Measured(A) - Reverse (it's the same with Target), Transmission Gear Engaged - "----", Transmission Range Sensor A (and B) Position - Measured - P (it was in Park the entire time), Transmission Range Sensor Position Corrected - Park, Transmission Range Shift Lock Output Allow - NO, Transmission Range Shift Lock Output Allow Status - Yes Error. What does not make sense to me are the Clutches A and B are read FULLY OPEN but it can't self calibrate itself because they're not OPEN? And 108 C seems a bit high for the fans to turn on. Things to note are the MAF sensor is not connected (removed to make space for the transmission plug), transmission red plug does not lock in place but I tried to close the pins on it and force it inside so it does not move, the old ABS module recently died and I plugged in a used one I had laying around but it wasn't for this car, ABS intermittently has loss of communication with the airbag module. I've been working on this car for weeks already and I have tested about everything I could think of, I checked every wire from the transmission red plug to the other side and everything checks out.

You have a bad ABS sensor or a hub bearing going out, taking the ABS sensor (the one that looks for ring tone from the hub spinning) but if the ABS system is not talking to the PCM - there's your ballgame.

Car will get warm when brakes drag so it may have brake / wheel / hub bearing issues more than Transmission - which - if not diagnosed, will turn into a condition of both requiring service if this doesn't get resolved.
