The one-time-use sealing washer under the transmission pan drain plug. The catalogue is specific about this on the Gen 3: this washer is the transmission drain plug's, not the engine's — the engine sump takes a different number — so do not let a counter hand you "the drain washer" and assume it is the right one. It seals by crushing, so it seals properly once. Reusing it is how a clean transmission service turns into a slow drip on the driveway a week later, and it is the cheapest part in the whole job. The number, the fitment and the count come from the Montero specialist's own catalogue page, cited below — a parts catalogue is good evidence for what a part number is and what it fits, and it is not factory literature, so read every figure on this page as the catalogue's claim rather than as a service-manual specification.
