Electric sockets of an automatic transmission
- 1 - ten-pin connector of magnetic valves;
- 2 - motion speed sensor;
- 3 - multifunctional switch;
- 4 - gearbox speed sensor
Warning: The main operations for removing and installing the gearbox are described in subsection 8.1.1. This section only lists the differences regarding automatic transmissions.
Removing
1. Lower engine and connect to clutch housing.
2. Support the engine with a crane by the lugs attached to the cylinder head or cylinder block. Disconnect the electrical connectors from the gearbox (see fig. Electric sockets of an automatic transmission).
3. Using a screwdriver blade, remove the cable end (1) from the lever (4), then release the locking bracket (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 transmission.
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 four bolts and remove a protective casing of a transmission.
7. Remove the plug and unscrew the three nuts securing the torque converter. Rotate the engine crankshaft to access the nuts.
8. Disconnect the drive shafts from the gearbox. When removing the gearbox, be careful that the torque converter does not fall out of the gearbox.
Installation
1. Before installing the automatic transmission, measure the distance between the gearbox 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 the gearbox is installed.
2. Further installation is carried out in the reverse order of removal, taking into account the following points.
3. To fasten the torque converter, you must use the original nut, which must be tightened to a torque of 60 Nm.
4. To attach the gearbox support, use new bolts, tightening them to the required torque. Bolt A - 60 Nm + tighten by an angle of 90°. Bolt B - 40 Nm + tighten by an angle of 90°.
5. Adjust the automatic transmission control cable.
6. Check the condition of the oil in the final drive and gearbox.
