I think source of the comment about this not being relevant is the fact that the guy in the video referenced that the aftermarket TCM he bought interfaces with the Mopar PCM. This makes it sound like the only way the TCM is useful is if you swap a Gen3 Hemi in at the same time.
But I am betting the manufacturer built the TCM to work with a non-EFI motor as well, if certain sensors like a TPS are added. In which case I would say it is a useful video, if not as informative as one where a guy swapped the 8 speed behind a carbureted LA.
But I haven’t check into whether the TCM needs a PCM or not. Just guessing.
