MASERATI QUATTROPORTE VI M156 8-speed automatic transmission

Maserati Quattroporte VI (M156) is equipped with the world-class ZF 8HP70 8-speed automatic transmission. This longitudinal unit is widely regarded as one of the best automatic gearboxes ever made, balancing lightning-fast shifts with the refinement expected of a flagship Italian sedan.

Because the Quattroporte M156 is available in both Rear-Wheel Drive (RWD) and All-Wheel Drive (Q4) configurations, the transmission housings and output sections differ significantly.

Technical Inspection & Installation Notes

As a specialist, ensure your team or the buyer follows these “Maserati-specific” protocols:

1. Oil Pan / Filter: The ZF 8HP70 uses a plastic oil pan with an integrated filter. These are prone to warping or weeping over time. It is best practice to install a brand-new pan and gasket kit during the swap.

2. Fluid Specification: Use ONLY ZF Lifeguard 8 or the official Maserati-branded fluid. Using incorrect fluid will cause “shudder” and premature clutch wear.

3. Adaptive Learning: After installation, the vehicle requires a “Service Adaptation” via a diagnostic tool (Leonardo, Texa, or Maserati DEIS) to allow the TCU to learn the new clutch bite points.

4. The “Park” Release: Ensure the manual park release cable (located under the car) is properly seated during installation, or the vehicle may remain stuck in Neutral.
