The planetary gear transmits torque from the engine at various gear ratios. The transmission fluid, which is under pressure, engages and disengages a number of hydraulic clutches and servo brakes in the planetary gear, thereby changing the gear ratio. The fluid pressure in the system is maintained by a separate pump. The transmission is controlled by a selector lever, which is fixed in 6 positions. In position D of the selector, automatic change of 4 speeds is ensured. For automatic switching of the transmission to a lower speed (increased gear ratio) when the throttle valve is fully open, a kick-down device is provided. In selector position 2, the car can move at speeds corresponding to the first two gear ratios, and in position 1 - only the first gear ratio. It is prohibited to switch the transmission to positions 1 and 2 if the speed exceeds 110 km / h. The selector has a button for switching the overspeed mode (engine braking or overload). Under normal driving conditions, this switch should be in the ON position, and when driving downhill or uphill, it should be in the OFF position. Any transmission repairs should be performed at a service station.
Removal
1. Raise the entire vehicle and place it on stands.
2. Move the selector to position N.
3. Remove the front wheels.
4. Drain the coolant, tighten the drain plug.
5. Remove the battery.
6. On GE16DE vehicles, remove the filter air duct.
7. Disconnect the wires from the dual switch and solenoid.
8. Disconnect the kick-down cable from the throttle valve.
9. Unscrew the nut and remove the cable from the bracket and clamps.
10. Disconnect the cable from the transmission lever, remove the bracket and remove the cable.
11. Clamp the coolant hoses, unscrew the fittings and disconnect the hoses.
12. Disconnect the axle shafts (see subsection 10.2).
13. Remove the exhaust pipe.
14. Remove the starter.
15. Remove the lower transmission housing cover and unscrew the torque converter bolts while turning the crankshaft.
16. Suspend the engine on a hoist or lift it with a jack.
17. Roll up a lifting platform and support the transmission.
18. Loosen the nut and remove the rear engine mount clamp bolt.
19. Unscrew the three bolts and remove the bracket.
20. Remove the restrictor ring.
21. Loosen the nut and remove the left engine mount tie bolt.
22. Unscrew the three bolts and remove the support and cushions.
23. Secure the torque converter.
24. Remove the transmission mounting bolts, having previously marked the location of each bolt (the bolts are of different lengths).
25. Make sure all necessary parts are disconnected and cannot interfere with removal.
26. Carefully move to the left and roll out the platform with the transmission.
27. Remove the pins if they become loose.
Installation
1. Installation is carried out in reverse order.
2. When installing the torque converter, check the distance from the bolt holes to the transmission split plane (A), which should be at least 21.1 mm.
3. Replace axle shaft seals, adjust kick-down cable.
Disassembly
Self-repair is not recommended, as it requires high qualifications and special tools. A car with a faulty transmission should be taken to a car service for diagnostics of failure codes and repair. The transmission can be removed only after reading the diagnostic codes.
