Michael, All ATF is wet clutch friendly, automatic transmissions all have wet clutches and bands. Not all wet clutch/band material is ATF friendly. Paragon and motorcycles use engine oil. Due to the fact that their clutch material is designed for use in motor oil not ATF. On the same thought some clutch material is designed for Dextron (type A) and some is designed for type F (Ford). If your transmission says ATF type A, Use it and nothing else or you will be buying a new transmission.
