Q: What does code P232A mean?

TCM Request Forced Engine Shutdown. P232A means the transmission control module (TCM) has sent a formal request to the engine control module (ECM) to shut the engine down, usually to prevent damage from a severe transmission fault. The ECM stores this code when it receives that shutdown request over the controller area network (CAN) bus, indicating the TCM has detected a condition it cannot safely manage.
