What is it that you surgically removed? I'm curious as much as George.
Is it aluminum spinning assemblies?

The only diet I've given mine is the deletion of the go- cable, Moroso fabricated aluminum oil pan and various titanium and aluminum bolts for certain things like the pan bolts. Oh, and the convertor inspection cover got the boot as well, it weighed 1/2 lb.
My trans is heavier than most out there because of the rear pump with these push button/cable drive transmissions, but I do have more shift pressure for firmer shifts.
