ALL replacement engines have the AT in the serial number.
The AT replacement engine is technically a rebuilt unit, but almost everything in it is new.
The serial number will be at the bottom of the engine block, just above the oil pan cover - see this picture from my engine:

if no AT, then it is the ORIGINAL engine.
