Automatic transmission «A5S 440Z»
On automatic transmission «A5S 440Z» two speed sensors are installed - the output shaft and the turbine. Before replacing the speed sensors, it is necessary to remove the automatic transmission oil pan. The automatic transmission output shaft speed sensor must be replaced in the following order.
Remove the screw (arrow), remove bracket (1, fig. 9.86) and remove the sensor (2) from the gearbox housing. Disconnect the AL of the cable harness from the sensor.
When installing the automatic transmission input shaft speed sensor, the screw (M5) fasten its bracket to tighten with a torque of 5.0 Nm (0.5 kgf·m).
Replacement of the automatic transmission turbine speed sensor must be carried out in the following order.
Remove the screw (arrow), remove bracket (1, fig. 9.87) and remove the sensor (2) from the gearbox housing. Disconnect the AL of the cable harness from the sensor.
When installing the automatic transmission turbine speed sensor, secure the cable harness with a holder, screw (M5) fastening of the sensor bracket tighten to a torque of 5.0 Nm (0.5 kgf·m).

Automatic transmission «A5S390R»
Structural arrangement of sensors on the automatic transmission crankcase «A5S390R» shown in Figure 9.88.
On automatic transmission «A5S 390R» two speed sensors are installed - the output shaft and the turbine. Before replacing the speed sensors, the automatic transmission oil pan must be removed.
Replacement of the automatic transmission output shaft speed sensor must be carried out in the following order. Remove the automatic transmission oil sump and disconnect the loop (1, fig. 9.89). Remove bolt (2), remove the bracket and remove the sensor (3) output shaft from the automatic transmission crankcase.
When installing the automatic transmission output shaft speed sensor, the screw (M5) fasten its bracket to tighten with a torque of 5.0 Nm (0.5 kgf·m). Upon completion of work, check the oil level in the automatic transmission and, if necessary, restore it.
Read information from the fault memory of the ECU-KSUD and the EGS system. Check stored fault messages. Troubleshoot and erase information from the memory.
Replacement of the automatic transmission turbine speed sensor must be carried out in the following order. Remove the automatic transmission oil sump and disconnect the loop (1, fig. 9.90) from the turbine speed sensor. Remove the screw (2), fixing the bracket and remove the sensor (3) from the gearbox housing.
When installing the automatic transmission turbine speed sensor, fasten with a screw (M5) fastening the sensor bracket by tightening it with a torque of 5.0 Nm (0.5 kgf·m). Upon completion of work, check the oil level in the automatic transmission and, if necessary, restore it.
Read information from the fault memory of the ECU-KSUD. Check the fault messages entered in the memory and eliminate them. Erase information from memory.
