4MN Q8 (2019+): 8-speed ZF 8HP75 on 3.0T TFSI 55 TFSI and 60 TFSI. SQ8 (2020+): 8-speed ZF 8HP on 4.0T V8 TFSI. RS Q8 (2021+): 8-speed ZF 8HP on 4.0T V8 TFSI (590 hp). All Q8: Quattro with air suspension and 4-wheel steering.

ZF 8HP75: ZF LGF8. Change every 40,000 miles (30,000 for RS Q8 with performance driving).
ZF 8HP valve body: 1–2 days. Full rebuild: 4–5 days.
