Having problems with my tranny (4l60e)

My tranny is a 4l60e was rebuilt a year ago. 3 weeks ago i did a converter swap it a circle d 38 triple disc with lock up.. First when i started using it, It worked good for about a week, but then my partial lock up didnt want to kick in neither my towing hual i have to turn it off so it can work again.. I got a serives engine soon light. I took it to autozone and i got shift solenoids codes so i got the tcc and the other 3 new from decco.. And i im still having problems.. The stall is a 2e and im
Running nitrous 150 shot.. I know that converter is not for nitrous but it worked good in the track.. Idk if its my computer,tune or my stall

Was your PCM tuned for a high-stall converter?
If not, that is likely your problem.
The PCM is detecting slippage between the engine RPM and the tailshaft MPH and throwing various codes.

My vote goes to the tune as well, assuming the converter was broke in properly.
