Why this part
Paper gaskets compress unevenly and RTV leaves residue that contaminates fluid — neither belongs near a transmission you depend on. The steel core keeps this gasket flat and true, while the moulded silicone bead does the actual sealing work without sealant compounds. At $52.92 it pays for itself the first time you pull the pan and reinstall it without sourcing a replacement.
