brand new PCM sent in for unlock - question

so i sent in a brand new engine controller module for unlock vs the one in my truck (2019 ram 2500). when i ordered up the unlock service i attached an engine read only, not the engine and transmission.

i asked support if i made a mistake and they never answered my question, just instead told me that it shipped out today which i already knew.

hopefully someone on here can answer as i've been trying to get them to pull the outbound shipment if needed so i can send a full read of the truck (and you of course cannot call them and speak to a real person). did i make a mistake by only attaching an engine .hpt file to my order when i sent in the brand new PCM for unlock? or is the transmission controller a separate piece of hardware?

thanks,
