Automatic transmission type «A5S 440Z»
Replacing the hydraulic control unit of automatic transmission type «A5S 440Z» must be done in the following order. Remove the automatic transmission oil sump. Holding the clamping sleeve (1, fig. 9.59), loosen the nut (2).
Using a screwdriver, remove the lock plate (1, see fig. 9.49) and remove the cable (2) from the bracket. Unlock automatic transmission control loop and disconnect (undock) his.
Press clamp to the right (1, fig. 9.60) and remove it from the ShS case. Press the housing of the ShSa inside the automatic transmission case.
Loosen the screw, remove the bracket (1, fig. 9.61) and remove the sensor (2) speed from the automatic transmission crankcase. Loosen the bolts and remove the oil filter from the automatic transmission hydraulic control unit.
Remove screws (1, M6x30, 5 pcs.) hydraulic unit mountings (2, fig. 9.62). Remove all large head bolts (16 pieces, black dots, fig. 9.63), except for the bolt in the middle of the block (1). While holding the hydraulic unit, remove the last bolts (1) and remove the block from the automatic transmission case.
Installation of the hydraulic unit should be carried out in the reverse order, while making sure that the centering pin is present, which must go into the hole (1, fig. 9.64) on the gearbox housing.
When installing the hydraulic control unit, it is necessary to wind the leash (1, fig. 9.65) selector disc into the groove of the spool thrust (2).
Hex socket head bolts (M6x60, 17 pcs.) fastenings of the hydraulic control unit tighten to a torque of 8.0 Nm (0.8 kgf·m). Peripheral hexagon head bolts (M6x30, 5 pcs.) fastenings of the hydraulic control unit tighten to a torque of 8.0 Nm (0.8 kgf·m).
Replace O-rings of circular cross-section (1, fig. 9.66) oil filter (2) and lubricate the new ring with Vaseline. Oil filter mounting bolts and speed sensor mounting bolt, tighten to 5.0 Nm (0.5 kgf·m).
Replace the O-ring (1, fig. 9.67). Lubricate the O-ring for ease of installation (1) vaseline. When installing, the lock of the AL body must go into the groove on the automatic transmission crankcase.
Adjust control box lever. Upon completion of work, check the oil level in the automatic transmission.
Automatic transmission type «A5S 390R»
hydraulic block (1) automatic transmission control type «A5S 390R» shown in Figure 9.68.
Replacing the hydraulic control unit of automatic transmission type «A5S 390R» must be done in the following order. Remove the automatic transmission oil sump and disconnect all loops from the hydraulic control unit. Remove the temperature sensor from the holder (1, fig. 9.69) automatic transmission. Since April 2000, the temperature sensor is built into the wiring harness.
Mark the location of the bolts, as they have different lengths. bolts (1, 2 pieces, fig. 9.70) do not turn out. Loosen all other screws (arrows) mounting hydraulic control unit with outer dimension «Torx E8» and remove the hydraulic block. Installation of the hydraulic unit should be carried out in the reverse order, if necessary.
Blow out all threaded connections with compressed air. Screw in the set screws (1, fig. 9.71) from the sealing kit, into the threaded holes.
Bolt length (1 and 2, fig. 9.72) is 68 mm, the other bolts are 58 mm. Install the hydraulic control unit on the two set bolts and secure it with the remaining bolts by hand-tightening. Remove the two set bolts and install the mounting bolts in their place, hand-tightening them. Tighten all bolts (M6) fixing the hydraulic unit in the order shown in Figure 9.72 with a torque of 11.0 Nm (1.1 kgf·m). screws (1 and 2) until tightened.
Install guide (1, fig. 9.73) automatic transmission switch into the retaining spring (2).
Attention! Leash (3) disc selector must be in the groove (4) spool pulls.
Insert probe (1, fig. 9.74) between fixing spring (2) and selector dial (3) and adjust the distance to 0.80 mm by moving the fixing spring (2).
Tighten the screws (4, M6) torque 11 Nm (1.1 kgf·m). Upon completion of work, check the oil level in the automatic transmission and, if necessary, add it.
