Does anybody know any links that will help answer some of these questions?

After a little more research I think the tranny I have is actually a w55.

you want the R154, overall its a stronger transmission and can take a lot more power than the w58 can.

there is this forum, Supraforums, and SupraMania - Powered by vBulletin. stay between these three forums and youll be fine for all the information that you need.

there were diagrams of a w58 and r154 to tell them apart, but i dont have them bookmarked or know offhand myself...im automatic. ill browse for em, but cant promise ill find them.
