Removing gearbox - vehicles with 6-cylinder fuel injection engine — AUDI

🧭 Before you start

After the battery, plenum seals and bracket set-up, the car is raised and the exhaust and catalytic converters, then the transfer box, are removed. Lower engine-to-gearbox bolts, the starter and the exhaust bracket follow, then the slave cylinder, coolant pipe bracket, reversing light switch connector and breather line are freed and the upper bolts reached with extensions. The gearbox support is fitted with its adapters and bolted to the gearbox, the wooden block from the transfer box removal is taken out, and the gearbox is lowered while the rear spindle is readjusted. The last bolt comes out, the input shaft is drawn out of the clutch, the selector cables are released and the gearbox is guided past the exhaust pipes, front final drive and subframe.

Fits: Audi Q7 (4L, 2005–2015)

Don't miss

• Get the radio anti-theft code before disconnecting the battery if a coded radio is fitted.
• Secure the bracket support with the retaining pins and split pins of the connecting pieces.
• Activate jacking mode on air-suspended cars before raising them.
• Do not open the slave cylinder hydraulic connections; tie it up intact.
• The plugs marked in the procedure must be installed after the gearbox goes back in.

2. With the ignition switched off, disconnect battery earth strap Electrical system27.
3. Remove profiled seals and seal for plenum chamber General body repairs, exterior55.
4. Set up support bracket10-222A with adapters10-222 A/22, connecting pieces T40091/3 and adapter T40093/6 on wing mounting flanges.
5. Insert threaded rod of short spindle10-222A/10 through slot in adapter T40093/6. At the same time engage hook on rear engine lifting eye. [Note: The support bracket10-222A must be set up so that the spindle10-222A/10 does not contact the plenum chamber (arrow).Use thrust pad from assembly tool10-222A/10 to keep the spindle3301 straight when it is turned.]

6. Attach remaining parts of support bracket as shown in illustration. Set up adapters T40093/3 on metal flanges of longitudinal members. To do so, push refrigerant line (left side) slightly to one side.

24. Unclip pipe/hose line from retainer (2) on gearbox.
25. Remove bolt (1) and pull out slave cylinder to the rear.
26. Tie up slave cylinder (do not open hydraulic connections).
27. Remove bolt (3) and detach bracket for coolant pipes (4) from gearbox.
28. Unplug connector (1) from reversing light switch F4(arrow).
29. Unclip breather line (A) for gearbox from bracket (B) and pivot breather line downwards.
30. Remove top engine/gearbox securing bolts (arrows). [Note: These securing bolts are accessible from behind the gearbox with the appropriate ratchet extensions.]
31. Insert gearbox support3282 in engine and gearbox jackV.A.G 1383 A.
32. Align arms of gearbox support according to holes in adjustment plate.
33. Secure adapterVW 771/40 on left side of gearbox in threaded hole for securing bolt for slave cylinder.
34. Screw adapter3282/54 onto front left post of gearbox support.
35. Position engine and gearbox jackV.A.G 1383 A with gearbox support3282 under vehicle.
36. Secure gearbox to gearbox support3282 using bolts (A) (M10x20) and (B) (M10x30).
37. Now raise gearbox enough so you can remove wooden block (A) (inserted between gearbox and subframe when removing transfer box).
38. Then lower gearbox carefully with engine and gearbox jackV.A.G 1383 A. [Note: While lowering the gearbox, keep readjusting the rear spindle10-222A/10 on the support bracket10-222 A. Use the stepladderVAS 5085.]
