Seals and gaskets are an easy one given the advancement in plastics. On parts, aftermarket transmissions pan comes to mind. I just replaced my TH350 pan with a cast aluminum one with fins and a drain plug, along with a Moroso rubber over steel gasket that is reusable. It's a lot better that the flimsy gasket that came with the pan, and better than cork that absorbs the very fluid it's supposed to seal. The cast pan provides a smooth machined gasket surface for better sealing. The drain plug is for convenience and the fins may improve cooling.
