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.
- hef19898 3y ago"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.
