The 4R70W is the evolution of the AODE, which of course came from the AOD. The number in the modern models' names indicates the torque they're rated to handle, divided by 10. So a 4R70W (AOD) can handle 700 lb-ft, & an E4OD (4R100) can handle 1,000. Since the E4OD is one of the longest & heaviest (& expen$ivest) transmissions Ford ever made, it's totally reasonable for them to use the 4R70W in the lighter trucks with weaker engines.
