I've been looking at the EPC to determine which parts to order for my transmission, but am confused--if a part has been replaced by a newer one, but the applicability of the newer part is for a transmission number higher than mine, which part do I order? Can I/should I order the latest part, even though the applicability is for a number higher than mine? Or must I stick with the part associated with my transmission number, even though the part has been "replaced by...". BTW, I'm looking at B2 valve parts.
