A B5 S4 manual swap is a complex but feasible conversion from the factory Tiptronic automatic to a 6-speed manual transmission, requiring a complete set of donor parts and specific electronic reprogramming. The project is often undertaken by enthusiasts seeking better performance and control.
Required Parts B5 s4 manual swap
A complete swap requires numerous components, which can often be sourced as a full conversion kit from specialized Audi parts suppliers or gathered individually from a donor vehicle.
- Transmission: A 01E 6-speed manual transmission is the standard choice.
- Clutch Assembly: Flywheel, clutch disc, pressure plate, and all associated bolts are needed.
- Hydraulics: Clutch master cylinder, slave cylinder, and the associated fluid lines.
- Pedal Box: The complete manual pedal assembly.
- Shifter Mechanism: Shift linkage, shifter, shift knob, and boot.
- Driveshaft: A manual-specific driveshaft is required, often needing modification to fit correctly.
- Differential: A matching rear differential (typically 4:11 ratio for the B5 S4) should be used.
- Axles: Manual-specific front axles may be needed.
- Engine to Transmission Spacer: A specific 11.2mm thick spacer is crucial for correct fitment.
- Electronics: Specific wiring pigtails for the clutch pedal and a tuned/re-coded ECU and ABS module to eliminate check engine lights and ensure proper function
