Installing gearbox - all vehicles with 6-cylinder engine — AUDI

🧭 Before you start

Fits: Audi A6/A7 C7 (4G, 2011–2018); platform code 4X

• Opens: gearbox oil
• Renewed: needle bearing in drive plate

Don't miss

• There is only one inspection hole at the periphery; turn the clutch module accordingly.
• (Items 2 and 3) can be disregarded.
• The following step is essential to ensure that the clutch module makes even and proper contact on the drive plate and does not cant.
• Items marked (2) and (3) can be disregarded.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Position gearbox on gearbox support T40173 and secure with tensioning strap (1), as shown in illustration.
2. Check input shaft for scoring around bearing in drive plate (arrow). Renew needle bearing in drive plate if necessary 13Cylinder block (gearbox end); Renewing needle bearing in drive plate.

21. Raise gearbox further and tighten bolts (arrows) for tunnel cross member .
22. Detach engine and gearbox jackV.A.G 1383 A with gearbox support T40173 from gearbox.
23. Remove support bracket10 - 222 A.
24. Remove tensioning strap T10038 from engine/body brace.
25. Tighten remaining engine/gearbox securing bolts (3 … 5). Tightening torques
26. Remove transportation lock T40170 and assembly aid T40169.
27. Engage 6th gear by pulling out selector shaft (1) and shifting gear selector lever (2) forwards in direction of (arrow).
28. Fit both front wheels but do not torque down wheel bolts. [Note: The following step is essential to ensure that the clutch module makes even and proper contact on the drive plate and does not cant.]
29. Turn both front wheels together in one direction until the clutch module has turned through one complete revolution (360°).
30. Install first bolt (arrow) and tighten hand-tight (2 Nm). — 2 Nm (1.5 lb-ft)
31. Turn both front wheels so that clutch module turns 180° further in direction of engine rotation.
32. Install second bolt and tighten to specified torque .
33. Tighten remaining five bolts (including first bolt installed), turning crankshaft 60° further each time. Tightening torque
34. Secure intermediate steering shaft to steering rack Running gear, axles, steering48Steering column; Removing and installing intermediate steering shaft.
35. Attach electrical connectors (1) and (2) on power steering control unit J500.
36. Install subframe cross brace Running gear, axles, steering40Subframe; Exploded view - subframe.
