OVERVIEW
Genuine VW/Audi Transmission-to-Engine Shoulder Bolt M12 × 67mm
N-904-954-04 is an original Volkswagen Group fastening component that secures the transmission case to the engine at the assigned mounting positions. The confirmed Passat profiles below identify the original gearbox arrangements and fastening locations that specify this exact part. One individual bolt is supplied.
Technical details
- OEM number: N-904-954-04 / N90495404.
- Catalog identity: Shouldered hexagon-head bolt.
- Factory specification: M12 × 67; 12mm nominal metric thread diameter and 67mm nominal catalog length.
- Profile visible in the original photo: external hexagon head and integral seating collar.
- Assembly: Assigned engine-to-transmission mounting-hardware position, as detailed in the fitment table.
- Supply: One individual component; related bolts, nuts, washers, sleeves and brackets are separate items.
A mounting assembly can contain several similar-looking bolts with different lengths and assigned positions. Using the specified bolt preserves the intended seating arrangement at this location; the nominal M12 thread size does not make another transmission bolt interchangeable.
Common reasons to replace
Common replacement reasons include a damaged or rounded hexagon, stripped or corroded threads, a distorted collar, or missing hardware. Inspect the component during transmission removal and refitting, and follow the applicable original instructions where hardware renewal is required. Correct fastening hardware helps restore the intended assembly at the specified mounting point.
Check the complete mounting joint before selecting replacement hardware. Incorrect alignment, damaged mating threads, worn alignment sleeves or a distorted seating surface need their own repair. Replacing this part alone will not correct those conditions. A transmission noise, vibration or starting concern is not sufficient evidence that this particular component has failed; diagnose the complete assembly and identify the affected fastening point.
Installation and service notes
Verify the full OEM number, installed gearbox code and exact original fastening position before purchase. Engine-to-transmission mounting arrangements can vary by gearbox and drivetrain, and parts at adjacent catalog positions can have different specifications. Keep removed hardware organized by position rather than choosing replacements by appearance alone.
Inspect the bolt's receiving threads and any associated alignment sleeve. Start it by hand and verify that its seating collar bears against the correct surface. Do not use the mounting bolts to pull a misaligned engine and transmission together. Follow the applicable service procedure for access, component support, assembly sequence and final tightening. Tightening values and any renewal requirements belong to the complete original joint and must be taken from the vehicle-specific procedure. Do not substitute a generic torque or add an unverified thread treatment.
