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.
Q8 is Audi's flagship SUV - ZF 8HP work requires proper tooling and VCDS programming for adaptation after valve body service. RS Q8 V8 applications demand more frequent fluid changes due to sustained high-temperature operation.
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.
Fluid service and inspection complete the same day. Solenoid or sensor replacement: 1 day. Torque converter or seal repair: 2 - 3 days. Full rebuild with road test: 4 - 6 days. Time estimates assume parts in stock - call (312) 626-8759 to verify availability for your specific vehicle.
Every vehicle needs diagnosis before anyone can promise a repair path. These are the situations we help organize before you decide what to do next.
Tell us when it happens, whether reverse still works, and if warning lights are on. A scan and fluid check come before guessing at a rebuild.
Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.
A failed solenoid, valve body, converter, or internal clutch problem can lead to very different repair paths. The goal is a clear diagnosis and written estimate.
ZF 8HP solenoid or valve body wear - common at 60 - 100k miles without regular fluid service.
The RS Q8's transmission will overheat in sustained track use - it's designed for road use, not circuit racing. An aftermarket transmission cooler is recommended for track days.
4 - 5 days.
Same ZF 8HP platform, different torque spec for V8 applications. Same failure modes, similar repair costs.
Yes - VCDS programming handles all adaptation including air suspension height correlation.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
