1. Disconnect the ground cable from the battery and remove the battery and its holder.
2. Remove the air suction hose.
3. Place the front of the car on supports or drive the car into a viewing hole.
4. Disconnect the switch valve cable harness plug on the automatic transmission and disconnect the reversing light switch cable.
5. Disconnect the shift cable on the side of the gearbox and disconnect the throttle actuator for the gearbox on the engine side.
6. Drain gear oil.
7. Remove power shafts as it is described in the Head Clutch and drive shafts.
8. Disconnect the speedometer cable.
9. Place a lift under the engine. A hydraulic lift is best suited for this. Insert a piece of wood between the lift and the oil pan.
10. Install a mobile jack under the gearbox and lift it up slightly.
11. Disconnect the hoses from the oil cooler on the underside of the radiator. Collect the leaking oil.
12. Unscrew and take out a starter.
13. Unscrew the middle suspension carrier of the power unit and remove it. Make sure that the engine and gearbox are securely supported.
14. Unscrew the cover on the back of the torque converter housing and unscrew the drive plate bolts from the torque converter. At the same time, rotate the engine to get to all the bolts. The transducer must be held with a screwdriver so that it cannot turn.
15. Remove the mounting bolts between the engine and gearbox and separate the units from each other. Mark the torque converter with a scriber so that it can be installed in its original position.
16. Remove the left suspension bracket of an automatic transmission.
17. Slowly pull out the mobile lift with the gearbox on it. Be careful not to damage surrounding parts.
18. Installation of an automatic transmission is carried out in the reverse order.
19. Slide the torque converter onto the shaft and check that the distance from the end of the converter to the surface of the gearbox housing is 15.9 mm. Measurement is taken from the end of the box surface to the front of the transducer (illustration below).
When installing the torque converter, measure dimension A as shown using a steel straightedge (1) and measuring ruler (2).
20. Check that the labels on the transducer match.
21. Lubricate the threads of the driven disc bolts with grease, tighten the bolts in order. It should be remembered that the bolts have different lengths and tightening torques. In addition, some bolts hold the gearbox to the engine, and some vice versa hold the engine to the gearbox. Fastening is carried out as shown in the illustration below. As an illustration, consider the following:
Mounting the gearbox on the engine in the variant with the injection system
Bolt length "I": 1 - 55 mm; 2 - 65 mm; 3 - 35 mm; 4 - 45 mm
Tightening torques: 1 and 2 = 70-80 Nm; 3 and 4 = 16-21 Nm
- Bolts in positions (1) on the upper side and directly below them are 55 mm long and are tightened with a force of 70 - 80 mm.
- Bolt in position (1), bottom right (see illustration above) has a length of 50 mm and is tightened with a force of 70 - 80 Nm.
- Bolt in position (3) has a length of 35 mm and is tightened with a force of 16 - 22 Nm.
- Bolt in position (5) has a length of 45 mm and is tightened with a force of 16 - 22 Nm.
- Bolt in position (2) has a length of 65 mm and is tightened with a force of 70 - 80 Nm.
22. Fill the gearbox with oil (type Dexron II).
23. Connect the shift cable and adjust it (see Section Automatic transmission adjustment).
24. Check the oil level in the final drive.
