So true. Some Paragons use motor oil. There are some transmissions set up to use the engine oil as their lube. If I remember correctly an Atomic four uses the same oil for both Transmission and engine. In fact the same pan on the Atomic four.
Other Paragons and Walters use 30 wt as well. After the 200 series the transmissions used ATF.
