PRY gearbox Audi S1 ​​manual transmission 6-speed 4WD 2015 63km

Transmission Type: 6-Speed Manual (0A8 Family)

Mileage: 63 km (Delivery Mileage / New-Old-Stock)

Year of Manufacture: 2015

Drive System: Quattro All-Wheel Drive (4WD)

The PRY is the heavy-duty 6-speed manual gearbox exclusively paired with the 2.0 TFSI (CWZA) engine in the Audi S1 and S1 Sportback. Unlike almost every other modern “S” model, the S1 was never offered with an automatic S-tronic option, making the PRY the definitive transmission for this “pocket rocket.” At 63 km, this is a rare find, essentially offering factory-new mechanical tolerances for a vehicle produced over a decade ago.

Technical Specifications

• Gearbox Family: 0A8 series (Magnesium housing for weight reduction).

   

• Torque Rating: Specifically valved for $370\text{ Nm}$ peak torque.

• Internal Ratios: * 1st: $3.357$ / 2nd: $2.087$ / 3rd: $1.481$

  • 4th: $1.088$ / 5th: $1.097$ / 6th: $0.912$

• Final Drive: $3.944$ (Gears 1-4) / $3.087$ (Gears 5, 6, and Reverse).

• Quattro Integration: Features a specialized output flange for the longitudinal prop-shaft leading to the rear Haldex-based multi-plate clutch.

Key Performance Features

• Short-Shift Geometry: The PRY is known for its exceptionally short and precise gear throws, designed to match the S1’s agile 2,469 mm wheelbase.

• Low-Ratio Bias: Gears 1 through 4 are stacked closely to keep the EA888 engine in its peak power band ($1,600\text{–}3,000\text{ RPM}$ for max torque).

• Quattro Architecture: The transmission includes the bevel gear unit required to send power to the rear axle. Because the S1 uses a specific rear-axle layout (Four-link independent suspension), the PRY’s output is calibrated for this unique subframe.

Professional Installation & Maintenance

1. Fluid Specification: Requires Audi G 052 171 A2 (SAE 70W-75).

   • Pro Tip: Even though it has only 63 km, if the unit has sat for years, we recommend a fresh fill to ensure any internal condensation is removed and the synchronizers are properly lubricated.

2. Clutch Pairing: It is designed for a $240\text{ mm}$ single-plate dry clutch. For a 2015 S1, ensure the Dual Mass Flywheel (DMF) is inspected; if you are installing this “new” gearbox, a new clutch kit is highly recommended to ensure shift quality matches the gearbox’s condition.

3. Bevel Gear Oil: The front transfer box (Quattro output) often uses a different fluid than the main gear-set. Check the fill levels on both the main housing and the transfer unit separately.

4. Shift Linkage: When installing, the shift cables (Part No. 8X0 711 721) must be reset to the “neutral” position using the locking pin on the gearbox selector tower to prevent grinding into 1st or Reverse.

Interchangeability

• Part Number: 0A8 300 044 H

   

• Compatibility: Directly interchangeable with the CWZA engine code. While it physically fits the A1 chassis, the PRY is specific to the 4WD S1; it cannot be easily used in a standard FWD A1 without massive modifications to the floor-pan and rear axle.
