@washerdude - you're correct. Whirlpool still makes the 3360629 transmissions for Direct Drives. Techs still buy and replace them and due to horriffic manufacturing tolerances by Whirlpool, they're nearly unusable or may last 3-5 years if the consumer is lucky. You're far better off to rebuild an old one that buy a new one for $250 from Whirlpool, they are just that bad.
I've had interviews with engineers that are designing this stuff, or know the engineers that are, at Whirlpool and other companies. I would get smacked with a Cease & Desist and lawsuits if I aired those interviews because of how damning they are against modern design theory on appliances.
To put it bluntly, they do FEMA analysis to design the machine within a very specific tolerance of years that the machine will last. Its maybe 5 years for a washer, 10 for a fridge. But if its after the warranty period (which they have very exact numbers on), they really don't care. That's why you see so many issues with the machines at year 2 to 3 that they don't solve.
Recently, I had a discussion with a product manager at one of the big appliance manufacturers. Once we finished the powerpoint pitch deck on their products and how they should be used, I asked them, very specifically, why their boards were failing causing issues XYZ (this company is consistently out of boards across their product lines and techs have been badmouthing the failures for a year or two now). The product guy had absolutely no clue they were failing. None at all, despite how notorious the system is.
Its a systemic issue. They don't know and don't care unless it costs them in the short term via a recall. But when you repair or help people fix things, you don't deal in that side of things.
So we end up getting stuck with short lifespan appliances. The other side of the coin of truth is that consumers usually don't want to pay for a well-built appliance often, either. You aren't going to get a reliable machine build for $500 in most cases in the US between tariffs, American manufacturing costs, and so on. If you look at any old classic machine that we know and love - Maytag Dependable Care, GE Filter-Flo, Whirlpool Direct Drives, ect, they cost well over $1,000 in current inflation-adjusted money for some of the mid-grade models (much less $1,500 for a higher end one like, say, a Lady Kenmore in matte black). So customer perceptions and demands have to change too. If the companies start having product failures because consumers don't want crap or extra features, the corps would pivot. But... They aren't getting that feedback from consumers sadly. Unless your Speed Queen and are OK with a 1% market share and don't want to go for the killing blow against the other manufacturers.
