Gearbox 4X4 Audi S4/S5 3.0Tfsi built in 2017 code SHP with 4,914km

Transmission Type: 8-Speed Tiptronic (ZF 8HP55 / AL552)

Mileage: 4,914 km (Near-New / Grade A+)

Year: 2017

The SHP is a high-performance 8-speed automatic transmission manufactured by ZF for the Audi B9 platform (S4 and S5). In 2017, Audi moved away from the 7-speed S-tronic dual-clutch for the S-models, opting for the ZF 8HP because the new single-turbo $3.0\text{ TFSI}$ engine (EA839) produced a massive $500\text{ Nm}$ of torque from very low RPMs, which the torque converter of the 8HP handles with superior smoothness and durability.

Technical Specifications

• Gearbox Family: ZF 8HP55 (Audi designation: AL552-8Q).

• Torque Rating: Officially rated up to $700\text{ Nm}$, providing massive headroom for Stage 1 or Stage 2 tuning.

• Mileage: 4,914 km — This is a “Museum Grade” unit, essentially a brand-new gearbox removed from a low-mileage demonstrator or insurance-loss vehicle.

• 4×4 System: Integrated Quattro permanent all-wheel drive with self-locking center differential.

Key Performance Features

• Lightning-Fast Shifts: Despite being a torque-converter automatic, the SHP features optimized shift solenoids that allow for gear changes in under 200 ms, rivaling many dual-clutch systems.

• “AMAX” Mode: When Launch Control is activated, the transmission enters AMAX mode, which allows for shifts at peak torque with zero power interruption, optimized for 0–100 km/h sprints.

• Fuel Efficiency: Features a decoupling vibration damper and an ultra-wide gear spread (8 gears), allowing the $3.0\text{ TFSI}$ to cruise at high speeds at extremely low RPM.

• Reliability: Unlike the earlier 7-speed S-tronic units that suffered from mechatronic failures, the ZF 8HP is globally recognized as one of the most reliable performance transmissions ever built.

Professional Installation & Technical Notes

At 4,914 km, the internal clutches and gears are barely broken in. However, the electronics and software require precise handling:

1. Component Protection: The SHP gearbox is linked to the Audi Immobilizer system. Once installed, it will enter “Emergency Mode” (limited to 3rd gear) until the Component Protection is cleared via Audi ODIS and the unit is adapted to your vehicle’s VIN.

2. Fluid Verification: Although the mileage is low, if the unit has been sitting since 2017, the fluid (ZF Lifeguard 8 / Audi G 060 162 A2) should be checked for moisture. It is standard practice to use a new filter-pan and fresh fluid during installation to guarantee “factory-fresh” shift quality.

3. TCU Adaptation: The Transmission Control Unit (TCU) has stored “adaptive values” from its original engine. After installation, use VCDS or ODIS to perform a “Reset of Adaptation Values.” This forces the gearbox to re-learn the clutch kiss-points for your specific engine’s torque curve.

4. Hardware: The mounting bolts are one-time use stretch bolts. Always use new bolts (Part No: N91153101 for the main mounts) to ensure the transmission stays perfectly aligned under heavy acceleration.

Inventory Tip: This SHP code is specifically for the B9 S4/S5. While it looks similar to the 8-speed units in the A6 or Q7, the gear ratios and internal clutch counts are specific to the S-models.
