well...TCI probably does not make anything in the kit....just outside vendors...tci does not make clutch disc....raybestos and borg wargner do....tci does not make the steel disc...see first answer...
sealing rings...Transtar or transtec makes them....they all just rebox the vendors parts...
some transmission companies are willing to make a kit for you....add or remove parts .....other you get what is in the box...
