> Those latter two are, in modern cars anyway, lubricated for "life".

I don't believe there is a modern gearbox where the manufacturer of said gearbox says it never needs oil changes. The vehicle manufacturer might say that, but not the gearbox manufacturer.

Case in point - my 2021 Wrangler has a ZF 8 speed auto that Jeep says never needs an oil change. ZF says it needs an oil and filter change every 100,00km.

"Life" is open for discussion and definition. Going with ZF, the 8 speed is a great gearbox, saves the gearbox. Going with Jeep gets you a warranty replacement.

By the way, it is still possible Jeep modified the gearbox in some way, most OEMs do.
