Don't miss

• Before fitting a replacement gearbox, always blow through the ATF cooler and ATF lines with compressed air (not more than 10 bar) .
• Before installing, it is important to clean any residue from threads in cylinder block using a tap.
• There is only one notch at the periphery; turn the torque converter accordingly.
• Check whether aluminium bolts for engine/gearbox connection can be reused and mark bolts if necessary .
• The following step is necessary to ensure that the torque converter makes even and proper contact on the drive plate and does not cant.

🔩 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. Before fitting a replacement gearbox, always blow through the ATF cooler and ATF lines with compressed air (not more than 10 bar) .
2. Before installing, it is important to clean any residue from threads in cylinder block using a tap.
3. When fitting a replacement gearbox: attach gearbox support, gearbox mounting and tunnel cross member to new gearbox .
4. Position gearbox on gearbox support T40173 and secure with tensioning strap (1), as shown in illustration.
5. The following preparations must be made before joining the engine and gearbox:

6. Turn torque converter until hole is visible next to notch (arrow) in recess in bottom of gearbox housing, as shown in illustration. [Note: There is only one notch at the periphery; turn the torque converter accordingly.]
7. Insert transportation lock T40170 into gearbox housing from below and clamp onto flange shaft (1).
8. Check that dowel sleeves (A) for centralising engine/gearbox are in the cylinder block; install any missing dowel sleeves.
9. Check whether aluminium bolts for engine/gearbox connection can be reused and mark bolts if necessary .
10. Coat end seal (1) with lubricant before fitting.
11. Bring starter (2) and end seal (1) into installation position. To do so, use plastic/rubber wedge (4) to position starter in installation position while supporting starter on engine support (3). [Note: It is important to ensure that the end seal is in the correct installation position relative to the starter, as otherwise the securing bolts for the starter would be difficult to fit and the sealing function of the end seal would not be assured.] [Note: There are several different versions of this end seal (according to engine); for correct version refer to Electronic parts catalogue]
12. Insert top starter bolt (2) in gearbox.
13. Fit spacer sleeve (arrow) onto bolt (2).
14. Join gearbox with engine and tighten bolts (6 … 11).
15. Tighten starter using bolts (1) and (2), making sure that end seal is in correct position.
16. Remove transportation lock T40170.
17. Disengage spindles10 - 222 A /11.
18. Raise gearbox and tighten bolts (arrows) for tunnel cross member .
19. Slacken tensioning strap and move engine and gearbox jackV.A.G 1383 A with gearbox support T40173 out from underneath gearbox. [Note: The following step is necessary to ensure that the torque converter makes even and proper contact on the drive plate and does not cant.]
20. Press torque converter (2) slightly against drive plate (3) in direction of (arrow) using lever (1).
21. Secure torque converter to drive plate as follows: [Note: Use ring spanner insert, 16 mmV.A.G 1332/14, to tighten bolts.]
22. Install first bolt (arrow) and tighten hand-tight (2 Nm). — 2 Nm (1.5 lb-ft)
23. Turn crankshaft at vibration damper 240° in direction of engine rotation using counterhold tool T10355.
24. Tighten bolt (arrow) accessible in this crankshaft position to 60 Nm. — 60 Nm (44 lb-ft)
25. Turn crankshaft 120° further each time and tighten remaining two bolts to 60 Nm. — 60 Nm (44 lb-ft)
26. Tighten remaining engine/gearbox securing bolts (3 … 5).
27. Install ATF lines .
28. Install selector lever cable .
29. Secure steering column to steering rack Running gear, axles, steering48Steering column; Exploded view - steering column.
30. Install subframe cross brace Running gear, axles, steering40Subframe; Exploded view - subframe.
31. Secure drive shafts (left and right) to flange shafts of gearbox Running gear, axles, steering40Drive shaft; Exploded view - drive shaft.
32. Install heat shield for drive shaft .
33. Install propshaft Rear final drive39Propshaft; Exploded view - propshaft.
34. Install exhaust system and perform stress-free alignment 26Exhaust pipes/silencers; Exploded view - silencers.
35. Install noise insulation General body repairs, exterior66Noise insulation; Exploded view - noise insulation.
36. Connect battery Electrical system27Battery; Disconnecting and connecting battery.
37. ⚠ Overvoltage can cause irreparable damage to control units.Do not use charger for boost starting. — Check selector lever cable and adjust if necessary .
38. Check ATF level and top up as required .
