I have no idea how the tranny works in the truck, but in my mind it just seems like if it was mispositionned then it just wouldn't filter properly no ? kinda like an air filter ?
No, the main sump filter has a snout that sticks up into a bore in the pump housing. If the filter is mispositioned, so that the snout comes disengaged from the pump bore, then the pump sucks AIR (from around the filter snout) rather than sucking oil (up through the snout). That gives you no drive (or very little drive).
We typically do not see issues with the spin-on (cooler return) filter (which is also inside the trans) coming loose or falling off (although I have seen a few reports). Problems with the main sump filter are much more common, although usually they result from a botched fluid and filter change (not from misinstallation at the factory).
