Unable to read TCU 722.9 transmission

Hello Guys,
I've been having intermittent transmission issues, the P/D on the instrument cluster keeps dissapearing and appearing, when it dissapears the car goes into limp mode, sometimes it won't even engage any gears and will not move, it also causes the check engine light to come on and makes the engine run rough.
when the P/D dissapears it also makes the diagnostic tool not to be able to read the codes from TCU and says TCU NOT EQUIPPED during diagnosis.
I managed to get the codes when it reappeared and took screenshots
I got the diagnostic codes below:
