Automatic transmission electrical connectors
- 1 - ten-pin connector for magnetic valves;
- 2 - speed sensor;
- 3 - Multi-function switch;
- 4 - gearbox speed sensor
Warning: Basic operations for removing and installing the gearbox are described in subsection 8.1.1. This section only covers differences related to automatic transmissions.
Removal
1. Lower the engine and connect it to the clutch housing.
2. Support the engine with a crane using the lugs attached to the cylinder head or cylinder block. Disconnect the electrical connectors from the gearbox (see picture Electrical connectors of automatic transmission).
3. Using a screwdriver blade, remove the cable end (1) from the lever (4), then release the retaining clip (3) holding the control cable sheath and move the cable to the side. Do not unscrew the bolt (2).
4. Unscrew the power steering support bracket from the gearbox.
5. Using clamps such as VW 3094, pinch the hoses going to the automatic transmission. Loosen the clamps and disconnect the hoses from the automatic transmission.
6. Unscrew the four bolts and remove the gearbox protective cover.
7. Remove the plug and unscrew the three nuts securing the torque converter. To access the nuts, turn the engine crankshaft.
8. Disconnect the drive shafts from the transmission. When removing the transmission, be careful not to let the torque converter fall out of the transmission.
Installation
1. Before installing the automatic transmission, measure the distance between the transmission flange and the bolt flange, which should be about 22 mm. If this distance is about 10 mm, then the torque converter is not installed correctly. If the torque converter is installed incorrectly, the leading part of the torque converter is destroyed when installing the transmission.
2. Further installation is carried out in the reverse order of removal, taking into account the following points.
3. To secure the torque converter, use the original nut, which must be tightened to a torque of 60 Nm.
4. To secure the gearbox support, use new bolts, tightening them to the required torque. Bolt A – 60 Nm + tighten by 90°. Bolt B – 40 Nm + tighten by 90°.

5. Adjust the automatic transmission control cable.
6. Check the condition of the oil in the final drive and gearbox.
