Front wheel drive vehicles
Withdrawal
1. Place the vehicle on jack stands so as to provide free access to the engine compartment, as well as unhindered work under the vehicle. The gearbox is removed downward.
2. Disconnect the wire terminal «masses» (-) from the battery.
3. Turn out three top bolts of fastening of a transmission to the engine.
4. Disconnect the wire «masses» (-) from the gearbox.
5. Disconnect the speedometer and reversing light switch connectors.
6. Remove the wire harness clamps and disconnect the lambda probe plug.
7. Remove the engine mudguard.
8. Disconnect the front muffler pipe from the intake manifold, as well as the catalyst from the additional muffler..
9. Disconnect the rear transmission support beam (see illustration).
10. Disconnect the shift fork rod from the gearbox.
11. Disconnect the procon-ten safety cables from the gearbox.
12. Remove protective covers of semiaxes.
13. Disconnect the right and left axle shafts from the gearbox, having previously secured them so that they do not fall. Turn the steering wheel all the way to the left.
14. Remove the clutch slave cylinder. Do not disconnect the hydraulic hose.
15. Disconnect from above an arm of the mechanism of a gear change.
16. Support the engine to prevent it from tipping forward or backward.
17. Place a lift under the gearbox.
18. Disconnect the bracket of the left transmission support and the front engine support.
19. Turn out the bottom bolt of fastening of a transmission to the engine.
20. Press the gearbox away from the engine with a mount.
21. Lower the lift with the gearbox lying on it.
Installation
22. Before installing the gearbox, clean the splines of the gearbox input shaft shank and lubricate them with molybdenum paste or VAG G000 100 grease.
23. Make sure the thrust sleeves for centering the gearbox on the engine are in place.
24. Check the operation of the gearshift mechanism after installing the gearbox in place. Adjust the mechanism if necessary.
25. Cars with a six-cylinder engine. Finish the crankcase on the left side at the top with a 30°chamfer. Otherwise, the reception rude will rest.
Over time, the transmission may become noisy. In this case, first check the oil level in the box.
If, when one of the gears is engaged, a howling sound appears, which changes depending on the position of the accelerator pedal, then the reason for this may be the wear of the teeth of the pair of gears corresponding to this gear.
Noises in all gears are caused by a defect in the main gear or axle shaft bearings.
A sound similar to the work of millstones, which appears when the engine is warmed up to operating temperature, is a consequence of the beating of the synchronizer blocking rings. As a result of the dilution of the oil under the influence of temperature, it is pushed out by the blocking rings.
Attention! Workshops rarely agree to repair or overhaul the gearbox. When the box fails, the workshops offer the appropriate unit from the exchange fund. In most cases, costs can be reduced by installing a used box, which can be purchased at car recycling stations. In this case, make sure that the marking of the used box, stamped on the top of the case, matches yours.
