Let's not forget that even though the full-size direct drive washers were fully discontinued in 2011, the stacked sets were produced all the way through 2017. so I would think this means, and someone feel free to correct me if I am wrong, that even though machine-specific parts like timers will continue to become unavailable through Whirlpool, they will still offer their major parts that go in all their Dd machines, i.e., coupler, clutch and gearcase, until at least 2033. That's another decade, as noted above.
That said I heeded the warnings of individuals on here who told me the new gearcases are crap and went with a rebuilt one when my bro-in-law repaired my machine over Christmas.
